I have this 486PIG MP046 board which has multi I/O on board but weirdly enough, it doesn't have a floppy controller. I'd like to add a floppy drive (GoTek) so I have at least the ability to do alternative boots. I was thinking of taking any old multi I/O card, disable everything except the floppy …

LPX "Pizza box" desktops is my favorite, something about those dimensions. I agree. For systems that don't need major cooling, 286 and 386, I prefer LPX cases as well because it's easy to stack them. As a matter of fact, I recently build my 286 and 386 into two identical LPX cases: https://www. …

Today I installed that Creative 4x speed drive into my 386. Works perfectly fine. More pics of the drive itself: Re: Bought these (retro) hardware today

Recently won an Ebay auction on a Creative CD-ROM Upgrade Kit, brand new and sealed in-box. This will go well with my new(ish) 386 build.

Recently a seller on eBay was selling brand new Panasonic 1.2mb 5 1/4 floppy disk drives. Even though I have absolutely no use for it, since I don't have a single 5 1/4 disk anymore, I figured however, that my low-profile 286 build (brand new case) should have a 5 1/4 inch drive in it. So bought one …

I also got a Shuttle HOT 317 motherboard, with an AM386DX40 and cache. The only way to identify it was it says so on the BIOS EEPROM. It wasn't in such bad condition and may have booted / worked without cleaning up the corrosion. Now I've added in a coin cell instead of the NICAD battery. I …

I have this case, and it has quite a few openings for serial and parallel ports in the chassis. I have seen on other cases in the past that had these covers, either clip-on or with screws, but I'm not sure what to search/Google for. Does anyone know what these things are called and even better, …

Why do AT PSU's have this ground? connector and ATX PSU's do not? I'm saying "ground" with a question mark because I think that's what it is for but since I'm a total noob I'm using the question mark as a disclaimer... :) Also, if the PSU has this connector, is it mandatory to connect it? https://i. …

The M24 is similar: It's a motherboard on the bottom, an 'ISA backplane' on top, joined by the video card. I like it because it's weird. Als has the advantage that the leaking battery will not leak a lot on the PCB but on the case! https://www.vecchicomputer.com/wp-content/uploads/2017/07/olivetti- …

@Scali So, I did a bunch of reading and I tinkered something together. Inspired by the DoWhackaDo demo I have been trying to figure out how the logo was done (i.e. move behind and in front of the scroller) and I think I might have figured that bit out. It's basically a palette change but I'd love to …
