Wow the screen on that one looks great! I'm glad it was just the RTC battery that was stopping yours from working the same as it now does mine - I got a 4/25E which was a 486 with the active matrix monochrome display, but the only replacement board I could get was the 3/25 so now it's a 386 :) The …

Would 16MB sGram be even possible? Yeah I'm pretty sure it is. It's got some empty pads at R22 and R24 that look like my MSI MS-6168 v2 board - with options to connect Chip / Bank Select either to the A10 address line (R22) or Chip Select (R23), with another pad (R24) to hook Chip Select on the RAM …

There's evidence of corrosion in a few spots near to where the caps have leaked. Look at IC8 M51132L, I assume that's an amplifier or something? The solder joints don't look good and specifically the trace by the letter C of IC8 Similar thing with some of the pins / traces on IC3 as well, that …

Can also confirm that a Ti 4200 can run with a passive heatsink. I'm using a Zalman fanless cooler, which is basically two giant heatsinks connected via a heatpipe. Also have a couple 140mm intake fans that help push air towards it for good measure. Good that you've got some air blowing over it, …

Yep, that should work 😀 I can definitely run most of my laptops using a 65w power bank and the cables I made. That cable works the same way as the ones I made and will put the DC jack power output to 15v when plugged in.

Read this thread! https://www.vogons.org/viewtopic.php?t=76990 That POST code tester card design does *not* work for ISA and could cause damage to the computer if connected to the ISA slot. Probably fine in PCI though, but it's not a good POST code reader. "0000" might mean no code, the reader I use …

The 386 model can not power up if the RTC battery is dead. To change that you'll need to take it apart and pull out the systemboard which is in a big aluminium shell. The top case comes off and upwards by prying some plastic clips around the sides and maybe some screws in back? Not sure, mines in …

So I thought I'd update the bios using my TL866 programmer. It was all going great until I put the EEPROM in backwards. The POST analyser card now only shows "--" with it. The rom still reads okay on the programmer and I was very worried I'd killed the board? since the ROM connects directly to the …
