Hey everybody, It is that point of 12 months for #doscember #DOSCember2022 once more! I’ve put collectively a enjoyable little mission with some 386 …

Thanks hey everybody again once more and it’s that point of the 12 months it is dos Simba and um yeah all of the YouTubers get collectively and do some dos tasks and uh that is mine it is a case in the mean time however um yeah I must put some components into it and I’ve

Been amassing just a few bits and items over time so uh yeah I am doing one other construct now this mission goes to be a form of 386 construct um I have not had a 386 machine earlier than the final time I used one was in all probability oh will need to have been highschool the off casts

From the previous laptop labs and issues ended up behind my science classroom and um yeah acquired to play with them there however that was 2004 or 5 so yeah it has been some time and I have been that means to attempt to um pack a motherboard up and you understand do

A construct with one however you understand they’re getting a bit costly as of late uh however yeah I will get into that extra later however uh for now we have got to form of assemble this case which I’ve had um form of sitting round in storage for fairly just a few years really

Uh this has been one of the vital form of in-depth uh builds that I’ve achieved but um so it may be a little bit of a protracted one so you understand seize a drink or no matter you guys have gotten going and sort of sit again and benefit from the mission

Effectively after getting the case hinge uh Clips put again in place I moved on to the duty which I had been dreading which is uh getting the facility provide fitted uh so this case have to be for like a 80 uh nicely it isn’t an 80s model case however like

An XT or one thing equal uh it is acquired a date code of like 93 on the again there uh yeah it did not match aside from the motherboard it did not match any energy provides or customary you understand 80 or 80x energy provides so I needed to do a little bit of

Quote on quote fabrication to make that each one work which I will present right here later and this uh form of made the mission fairly a bit more difficult and nicely for me a bit extra attention-grabbing as a result of I really needed to do some work to make all of it match

So I borrowed some instruments for my flatmate Reuben um and yeah we did some work on the again panel fortunately it unscrews so here is the problem you’ll be able to see right here that The Jug wire or the IEC port or no matter you wish to name it um

Is simply too far down to suit between the Hole and in addition the screw holes don’t line up with the again panel so very irritating and that is why this case has been sitting round for 2 to 3 years as a result of Eric’s going to require fairly a

Bit of labor to make all of it match however I’ve form of had it in reserve able to go for a construct corresponding to this so what I am doing is attempting to line up the screw holes with the ATX energy provide that I wish to use for this construct

Um so I am utilizing a cotton bud with some Loctite on it so it would not form of evaporate and it leaves the markings on the again of the panel actually nice thought in concept till you do not line issues up fairly proper however nothing {that a} file cannot kind on the market so to get began

Drilling the holes out for the facility provide it’s a must to form of use a faucet form of factor or punch sorry that is what it is referred to as you’ll be able to inform I am actually good with my instruments right here um yeah simply to assist information and seat the drill piecing it was a little bit of a mission

As I mentioned to get this all to work however we’ll mark out the 4 holes that I would like after which Reuben right here helps me maintain the piece as a result of this Vice is a bit damaged whereas I drill out the holes oh yeah I informed you it’d grip yeah how a lot without end we acquired

Someone the lunches oh you go backwards oh I’m too what an fool Simply knocks these massive chunks off yeah so after drilling the proper approach round um it is only a matter of submitting down among the Burrows and issues like that and to assist therapeutic massage the screw uh holes to line up so subsequent is form of the larger job which was

Um ensuring that we may match the facility provide in between that gap the place Reuben’s thumb nicely was uh form of within the left there the place the facility wire goes in so for that um we acquired out the massive instruments overseas Thanks Sure I did use ear and eye safety on that one it makes an terrible racket however yeah prevent guys having to hearken to the submitting right here as a result of it appears like now’s on a chalkboard it simply wanted a bit extra massaging as a way to get the

Energy provide to suit form of correctly in there I ended up utilizing a mix of washers as nicely to attempt to area these on the market was one factor that I forgot to do which I will get to later which was mounting an influence change as a result of I’m utilizing an ATX energy provide

Um however anyway there’s nothing there one other um punch cannot kind out and a big drill piece however we’re gonna simply simply do a form of a mock match right here to ensure all of it traces up the case itself was very irritating to work with it is hinged and suited the entire lid

Simply coming off so it means my arm hold getting trapped within the lid I used to be mounting the facility provide very annoying very sore I’ve nonetheless acquired marks on my wrists from there um however anyway that might be worse however yeah you simply form of have to carry your

Hand in there as a way to mount the facility provide to the backing plate Thanks overseas Take this energy provide out and in just a few instances as I used to be becoming numerous parts into the case such because the motherboard and reminiscence and in addition the facility connector for the motherboard talking of the motherboard I discovered this one on commerce me an area form of Craigslist sort factor this motherboard

Is an elite group us 3486 that is sort of an attention-grabbing one it is a type of hybrid boards it supposedly helps a 486 and 386 CPU however as you’ll be able to see mine is lacking the 486 performance I sort of picked this one up for 2 causes um one it was

Form of low-cost it was about 75 U.S untested however um the opposite cause was it would not use a Vata battery so it will not leak all over the place it additionally got here with a 33 megahertz 386 CPU which may be very helpful as a result of I haven’t got of any of these and it is utilizing the UMC

Chipset it helps a most of 32 megabytes of reminiscence as nicely which is kind of a large quantity for a 386 or perhaps a 486 to be trustworthy um it got here pre-populated as nicely with 4 megabytes as you’ll be able to see no battery injury there on the header and I picked

Up the jumper consumer slash guide despite the fact that it was two pages from the Retro net mission I will hyperlink that within the description all proper subsequent job is to do away with the tantalum capacitors I imply they do not leak and you understand they usually will be

Fairly good I’ve had just a few explode on me earlier than and so I sort of wish to simply do away with them uh as a precautionary factor simply because after they explode you understand you’ll be able to’t learn the values off them as a result of the tops of them are ripped off um so what I’ve achieved

Um there was marking the capacitor places with a everlasting marker simply to form of present me the place I must go so I am like looking across the board and I am pre-tinning the um the leads of the prevailing capacitors and it will simply assist elimination of the prevailing ones

As a result of you understand lead three F3 versus you understand leaded photo voltaic so yeah simply helps you there with eliminating these And now I get to interrupt out my new favourite device which is the desoldering gun man this factor is superior overseas [Applause] Nonetheless getting the grasp of how the device works and you understand how to greatest observe it form of factor however um you understand I suppose I discovered by doing so just a few of those tasks and I believe I needs to be fairly good positively discovered that pre-tanning no matter you are attempting to take away helps

And giving it a great wiggle in fact not placing pressure on the board it’s kind of unruly this this one as a result of it’s kind of prime heavy however you understand it is all proper um however yeah I am doing these separately and the rationale I am doing that’s

As a result of lately I blew an influence provide up within a laptop computer as a result of I acquired the unsuitable voltages on the Caps combined up and yeah blew the tops off them so that you guys may see that um form of a failed restore however I will get to that later however yeah I am doing these

Separately and I had an attention-grabbing concern as nicely as a result of I do not belief among the silk display screen markings there’s two capacitors remarked incorrectly on the silk display screen for the grounding fairly essential with polarity for electrolytics I do not assume it issues a lot for the ceramic uh form of

Tantalum ones however um I might be unsuitable on that however yeah they had been marked form of incorrectly so I toned them out with my multimeter and carried on overseas International The connections for the facility connector and the keyboard simply due to the stresses they go below when you understand parts are being pulled out and in and issues like that I simply needed to ensure there was no breaks in there I do not assume it was vital however you

By no means know so I believed I’ve acquired the gun uh soldering iron out sorry I’d as nicely simply do it overseas Effectively after placing the whole lot in place it is time to minimize the leaves off all of the parts that is really fairly an pleasant half for me um I really went over the whole lot and double checked the polarity with my multimeter simply to be sure that I did not miss something like that may be

Fairly essential until you want exploding capacitors um however yeah all of it checked out fantastic which was good um and I believed what I will do can also be as a result of I’ve acquired all of the instruments out is construct some voltage blasters um it seems the facility provide I used to be utilizing did not require these however principally

It offers a adverse 5 volt rail out of your adverse 12 volt rail as a result of some Fashionable energy provides don’t present that anymore particularly if you happen to’re utilizing an ATX to at adapter um so I figured why not construct these up I have not constructed any pcbs earlier than um so I’ve linked this within the description

Um Phil’s laptop lab and necro the place there is a mission teamed up and you understand developed this and yeah it was quite simple course of I form of adopted the identical directions that these guys did and acquired all of them printed out and Yeah inside two weeks they had been right here

I ended up selecting the black PCB for all of those simply because I believed it regarded actually cool you understand having the white textual content on the black you understand background actually sharp elegant wanting oh yeah and I constructed just a few of those up it is fairly enjoyable really with the ability to

Put one thing collectively like this somewhat than having to you understand take one thing aside you understand I haven’t got to get the desoldering gun out however yeah as I mentioned the facility provide ended up packing for the mission ended up had um a adverse 5 volt rail on it anyway so these

Had been a bit redundant however hey I’ve acquired them in inventory and you understand I’ve acquired just a few different boards and issues that might use them so you understand why not make them up and plus if anybody wants one in New Zealand you understand I’ve acquired just a few pcbs

Kicking round yeah quite a lot of enjoyable to construct and due to these guys for growing this and releasing it to the neighborhood it is good things and you understand your personal advantages from it so shout out to them Thanks International Questions overseas Put it off lengthy sufficient I’ve cleared the stuff off my desk after constructing these little voltage glasses however I believe it is time we take a look at out the motherboard and really see if the untested unit works yeah I let loose a fairly large sigh of aid and I noticed that motherboard really posted

At this level you by no means fairly know our enjoyable examined half so yeah with that I will keep it up with the mission and um yeah I forgot to drill out a gap for the facility change uh once you’re utilizing an atx280 energy provide form of adapter you want a

Energy change as a way to activate the you understand PSU to activate so uh once I was final in Christchurch out of city I picked up some switches from jaycar I am unsure if these require some form of like bump capacitor or one thing on the change to assist forestall them burning now

I am not a electrical man however anyway I am fairly certain it is low voltage stuff for this one so I simply mounted a plain energy change up I believe this one helps like 5 or ten amps or one thing proper off the again of it so yeah that needs to be all proper I believe

Assume that is what it mentioned uh however yeah so I will simply flip the leads of the change and we’ll Mount the adapter cables to it I considered simply pushing the terminals on however I did not need them coming unfastened so I really eliminated the terminals from the cables you’ll be able to see

Them right here and I am simply going to solder the wires on to the the change simply to ensure they do not pop off Okay Um yeah I do know I haven’t got a correct warmth shrink melting device so I am simply utilizing a you understand Candlestick form of factor there however uh there’s the adapter anyway all mounted up I might have proven extra footage of mounting the motherboard into the case however the actuality is I had

To make use of a lot of totally different standoffs and put some rubber ft below the case as a way to get the board to take a seat degree um it took about 40 minutes to an hour to make that sort of all work so I do not wish to present all of that uh and yeah as

You possibly can see it is sort of a ache to get the facility provide and it’s a must to sort of lean over it the lid of the case is crushing my wrist um however that is the way it goes with previous computer systems simply throw in a few zip ties on

The mess of cables that I am not utilizing and I can simply simply form of Tuck these away beneath the floppy disk drive fairly helpful uh place to maintain the cables for storage um which is nice as a result of this case ended up feeling a little bit bit crammed to work and

Um yeah I do not know what it was I I have not labored for a lot of circumstances on this form of kind issue for fairly a lot of years really I’ve all the time sort of had Towers so yeah anyway new challenges uh hitters went on fairly good um did not have too many troubles of them

I managed to maintain all of it good and tidy as nicely for storage I had the selection of two choices this 545 megabyte model from a Seagate and a max-dore drive which was about 1 20 megabytes 120. I initially tried the 540 drive right here as a result of I believed a bit

Extra retailer storage can be good however in fact with the 386 uh form of error machines there is no laborious drive Auto detection so it’s a must to sort of set your cylinders and heads and stuff manually by both the labels which might be usually on the drives which these two that

I had didn’t have them printed out which is somewhat annoying or it’s a must to discover them on-line the second possibility that I went with um nicely for the secondary Drive is a compact flash to IDE adapter I actually needed to have the flexibility to take stuff

On and off the machine simply because I haven’t got a CD-ROM drive fitted or a community card and this does that is simply the following neatest thing actually uh IO is dealt with by this um form of Acer impressed mio-400 multi-controller it is a 16-bit card and I am simply wiring up the entrance header LED

For the laborious drive exercise and I discovered that it’s a must to sort of put the ribbon cables on for the drives first earlier than mounting the cardboard in as a result of it is actually laborious to get them in whereas the cardboard is form of mounted into the machine however yeah anyway I had just a few points with

That drive and I believe it was the settings I used to be placing in I do know that arduous drive works so ended up going for this Mac retailer unit made a 1992 April my God I am stunned it nonetheless works to be trustworthy nevertheless it’s a little bit bit quieter

Than the Seagate drive it makes a pleasant form of little hum it makes a little bit good chirping noise which you guys will hear quickly um however yeah it really works good as gold really each of those nonetheless work and it is superb contemplating how previous they’re and the way lengthy I’ve had them simply

Sitting round in a field however yeah not proud of the mounting system however I am assuming that shall be fantastic it nonetheless works till it eats itself aside however yeah get it plugged in and configured and provides it a take a look at actually I reckon I additionally added a compact flash card as nicely

Which is about one gigabyte in measurement far too giant and would not is not supported by this board however I simply halved my cylinder depend hopefully that is ok to work I do not know if that is what you are imagined to do nevertheless it detected a 512 Meg partition so yeah makes getting video games

Onto the machine quite a bit simpler overseas Making all the proper sounds is what you wish to hear out of a 386 so as a result of I haven’t got a bios battery put in or something like that to maintain the settings once you flip it off all of this will get misplaced it’s a must to reset it in however here is all my cylinders and heads

And issues like that that I needed to arrange for the drives and there is this device I discovered on a vogon’s hyperlink which I’ve put within the description as nicely for a device referred to as IDE data you set your drives as not put in then run this device from a Dos boot disk

Um makes it very helpful and it tells you all of your settings at this level now it is just about simply formatting the laborious drive and putting in MS-DOS it is a fairly customary of worry actually I ended up going with DOs 6.22 and I believed yeah that needs to be ok

Um and within the formatting of the drive despite the fact that it is solely a 120 megabytes you will see right here from the timer once I form of began the recording um yeah it takes some time to get via it it is gradual however you understand it will get there in the long run and I am stunned actually that the

Drive nonetheless works so yeah so after just a few brisk minutes it is just about simply keep it up with the setup as traditional sorry for the display screen adjustments right here I’ve had a hell of a time attempting to get this um footage captured as actually painful due to such a video card it

Simply regarded horrible it doesn’t matter what I did could not make it look good so yeah we’ll simply ignore that and keep it up uh simply feed the three floppy disks in after which we have got uh mstos 6.22 put in I am unsure if that is in all probability right for such a machine

Um I will need to allow you to guys inform me if the 6.22 was the best way to go uh however yeah apart from that it is just about simply going via and organising MS-DOS um as sort of like prayer that supplemental information that I did a pair

Of months in the past the place I arrange a mistos set up one in all my go-to’s is the Dos key interpreter as a result of you understand he can Tab out instructions and issues like that so yeah after a reboot of auto exec bat all of it labored out and I did a scan disk as

Effectively on the laborious drive simply to ensure there was no unhealthy sectors as soon as once more apologies for the horrible jailbars and video high quality it was simply as I mentioned a nightmare to get this recorded uh so transferring on I believed um 4 megabytes of RAM is a bit

Poultry so and why not add one other 4 um the identical man I acquired this motherboard off I acquired two others from as nicely for future tasks um and it had these little reminiscence modules already put in on uh one in all them so yeah I took all 4 off and now

We have eight megabytes of RAM and people checked out as nicely which I am tremendous blissful to see that there was no lifeless reminiscence transferring on to sound I pillowished components from a components machine um I am beginning to get low that is really my final ISO bass sound card uh

Sure it is a virus 16 however you understand it is ok for this machine um you understand it would not should be too fancy um however yeah apart from that it really works a deal with so you understand that is all the time helpful and now for the roles I have been placing

Off which is cleansing the case uh this was very marked off it is acquired quite a lot of scratches and dents and issues like that over it so I simply used the glass cleaner to get it began excellent place to begin takes quite a lot of the grime and stuff

Off the case in plastic so glass can cleaner is unquestionably a uh a great possibility to start with overseas I used to be sort of hoping the CRC stuff would loosen the sticky tape off a type of um 5 inch Drive Bay covers nevertheless it did not work so we went with a traditional

Which was simply the Magic Eraser sponge right here and uh took it off um there’s nonetheless a tiny little bit left nevertheless it appears to be like quite a bit higher than what it did earlier than and I simply went round the remainder of the case with this as nicely simply

Um over any marks and stuff to attempt to take away them it could actually take away textured supplies so um yeah simply be form of cautious when utilizing the Magic Eraser sponge subsequent up my colleague gave me a few of these um rainbow coloured pin header cable issues uh actually helpful for stuff like

This as a result of I needed to Route the PC speaker sound and thru the sound card so I may seize the audio and put my headphones on and stuff like that however yeah that was the final {Hardware} merchandise to wrap up all of it went very simply contemplating and I believe it is time we

Crack into some video games and see how the machine runs the 2 you are great From time to time you will hear sort of this beeping sound it is from the keyboard for some cause I am unsure if anybody else has had this concern however with this specific recreation uh it might be like a key would get caught and you’ll see right here that I am simply going proper and also you

Cannot transfer the participant after which once you respawn you retain going proper after which unexpectedly it should sort of simply cease after which will let you sort of transfer round after which I had quite a lot of bother exiting the sport as nicely as a result of the important thing

Would not work so yeah a little bit of a wierd one and I believe I’d attempt joystick or one thing on this one subsequent time thanks International thanks Thanks International overseas Hey overseas [Applause] overseas [Applause] overseas [Applause] This needs to be one in all my new favourite video games it is referred to as reptide and you understand you go round you have to shoot the enemies and stuff in your submarine however you’ve got acquired your little co-submarine referred to as Jason I believe his identify is you are gonna go round and choose up gadgets and

Open doorways off and stuff that your largest submarine cannot match via however yeah quite a lot of enjoyable taking part in this one overseas Thanks International International International Yeah the top of every degree you get a password as nicely it is sort of neat to throw in nicely that wraps up my dossimba construct on this one the primary ever 386 machine that I’ve constructed and owned so it has been a very long time since I’ve used

One as I mentioned however yeah hope you guys loved it it was quite a lot of enjoyable placing this one collectively it was a bit extra concerned with my traditional tasks and builds however that is the best way it goes uh however yeah with that I will catch you guys

Most likely within the new 12 months with some extra tasks and issues like that hope everybody retains secure and nicely over the vacation season as nicely and uh massive shout out to Reuben my flatmate he is acquired a YouTube channel which I will hyperlink within the description if you happen to’re into Subaru’s and

Automobile content material he does quite a lot of that however yeah thanks for watching catch you guys quickly companies
