Thanks for the advice everyone. I will try dumping it again tonight as if it were a 28-pin 27c256: Filename Screen Shot 2018-03-22 at 12.36.21 PM.png File size 166.08 KiB Views 2489 views All these variants of the 28-pin! Filename 512.png File size 84.49 KiB Views 2474 views

So it's a SPST toggle switch which has to be replaced with a momentary device. There's probably a part which is the same style of switch but the mechanical is momentary. You'd swap it out then. Filename switchswap.jpg File size 46.83 KiB Views 455 views

Can you elaborate or share photos? ATX cases have power switches. This AT one does not have the pair of 0.1" machine pin receptacles?

Thread: yes. Because hacking together a custom powersupply is cheap and easy today thanks to low noise dc-dc converters from china. As long as you know the voltages for each pin and supply enough current. It doesn't have to be perfect. I made my own ATX to AT adapter which worked alright. No reason …

Cut part of the back out for IO. Make the sure standoffs line up with card slots. Plug in the switch wires to the ATX board's pwr_sw header.

The only other chip I see in there is the 8042 keyboard controller. I don't have any ISA cards except for the VGA one--so no way to run software on it, otherwise I would compare the two methods. Could the BIOS be compressed? I see strings like "virus defense activated" "mr bios" and a list of the …

No, as in I have not flashed what was read back into anything and tested. But there are readable strings in it so at least some of it looks correct. The board posts on what it had originally. Here's my photo from the thread showing a 28-pin parallel eeprom (like the model keropi mentioned): https:// …

Very cool that someone did this! It is a photoshop joke. Over a decade later someone went all-out and had a custom PCB made to support all of the surface mount chips taken off other video cards. The only functional part of the card is the LED blink. The software is all scripted animations. The only …

I dumped a MR BIOS rom a few months ago here: Forgot how much old hardware I had I don't think it got put anywhere else yet. Last week I got a VGA card from ebay and confirmed the board POSTs.

Now you see for yourself that resolution does not indicate surface size of the picture display.

Do you know why you want higher than 800x600? (If even that works for gaming in a VM) It's going to depend on each game, most of which from that time, the answer is no. You should know that resolution does not indicate surface size of the picture display (because you're talking about 4K with Win98). …

Win98 era games were played on 4:3 CRTs at 640x480 and 800x600. A VM may not perform well enough for this. The Windows desktop resolution is not going to set the game to that or indicate that the game will scale appropriately. Black bars would be normal on the sides. Some games support modding or …
