Found acceptable dimensions. Looks like a good fit on the loose side so you don't have to hammer it down. Some kind of "handle" would be great on the roof part, but it would also make printing much more difficult. I think it's fine as it is for a couple of glue jobs.

Sweet! Lookin forward to what you figure out :p thanks! Case fitting could be two tents narrower. Lid fits but is a bit on the tight side. I think it would be perfect after some scraping with knife. In the end it should work well enough. Just made a quick sketch of the "two piece idea" and it …

Ooo sweet!!! Anyone with a printer able to send me one? I’ve been doing a bunch of these. And could use it! If you are sure it fits, post the file and I’ll add it to the guide. I'll test it properly next week. I can make a draft today with another printer to see is there hope. If it fits I'll post …

We need a 3d printed alignment tool for reinstalling the ihs squarely anyone able to make one? Something really basic like this one? CPU on flat surface and set this on top of it. Height is a few tenths less than CPU so you can add some weight on it. I haven't printed this yet but on next week I …

Is a broken CDROM drive nothing but scrap? Not necessarily. I need black 5.25" adapter for my Wyse because HDD fronts are also black so I came up with this idea. Designed and printed a new faceplate to CDROM drive chassis to mount a floppy drive in. Original was already lost. There are some full 5. …

I hate to say this but that is actually a "subwoofer". Also common port for stereo speakers would be just stupid. http://standardtelephone.com/gigagon/et/accspk.htm You can even rotate it 😁 There are also modern models f.ex. here https://www.quietpc.com/kama-bay-speaker-ace-bl

Re: Mounting an old 80486 motherboard in an old metal case
Posted on 2022-03-05, 13:09
A picture would help. Mounting an AT-motherboard usually needs these "slide in" stand -offs. Then there is one or more metal stand-offs to secure the board. So basically I just snap in all stand-offs and then slide the motherboard upwards in place. Then secure it with M3 screw.

Build 4P4C to DIN5 keyboard adapter used in Wyse 2108 and works perfectly. Some issues though with the system itself. Weird but after about 5mins system locks up. MFM low level format locked at about 90%. CPU gets really hot, cannot keep my finger on it. Also 80287 gets really warm. System doesn't …

The case is OK, not the worst for sure. After cleaning it should look great. Speeeeed display is set by pressing reset button, at least in the one I have.

(V): (ASUS/GIGABYTE) 12V: null/null 5V: 0.6kohm/1.2kohm 3.3V: null/null That looks like null is "over range" and results seems to be OK. Your looks like general garage level MM and results may vary when comparing. Yes, layout is a bit different. Looks like the bottom transistor is rotated 90 …

If that is correct, I am only reading a resistance with my multimeter on the 5V pins (all of them) and ground, and nothing on any 3.3 pins or the 12V pin and ground...not what you expected it seems? Well, sometimes I should look into mirror :) picture corrected. It depens what do you mean with " …
Re: P3B-F stopped working...need help

Here comes what I would do. Put multimeter to resistance mode, auto range or 1k should be fine. Touch 3.3V pin with red cable and GND point with black one. Resistance should start from low value and rise over to hundreds ohms and more, that just fine (resistance increases because multimeter is …
