Well, here's the before/after look :) https://i.imgur.com/bZDYBHjl.jpg?1 https://i.imgur.com/Opfop58l.jpg I've simply placed the new CR2032 battery holder in place of the old lithium battery. I even took the old battery's connector and velcro attach. So now the computer "future proof" :) Actually I …

Oh right !! I totally forgot about this. I shorted the ""+5V"" with GND using a 6.8K resistor that was laying around and it dropped to 0.02V. I guess there's nothing to worry about then. Here's the original battery

Tinnier cooler with a slightly different way of attaching should work. Maybe you can reverse just the attach so it doesn't get in the way ?

Don't forget the bragging rights, so you can tell everyone on the Internet that your gaming experience is of greater "purity" than everyone else's. :-P A virtual machine running XP appears to be a useful solution for running many older games these days, and for games that insist on Windows 98 with …

The cache chips used are pretty standard for 486 gears. You can try ISSI IS61C256AH-15N chips for example As for the JP5 usage, it's described in here in the "memory" category https://www.elhvb.com/mobokive/Archive/PcChip … 7_corrected.zip

If there's no other markings, from the color/design it looks like a Soyo motherboard that has lost its paper sticker (yes, Soyo is using paper stickers at the time as only means of labeleing/marking! ). This would mean we need the bios to wake up, for that you need to put back the oscillator that …

Ah I see, I was just wondering because I own this exact motherboard x) However 128MB for anything on socket 7 (even a K6-III) should be plenty 😀 (unless you aim to run Windows XP)
