Bought the following:
HardMPU MPU-401 card
DPT PM2022 EISA SCSI card
2x LT1084CP VRMs for my Socket 5 board
Pack of 10 SOJ-40 LIF sockets for easier RAM replacement
Nice, that HardMPU is really excellent for DIY hardware, it's 'just worked' with everything I've thrown at it so far with my MT-100 and SB-155 (the less cool MT-32 and SC-55). You've got the proper one that ab0tj made so it should work really reliably 😀
This has been a really fun christmas, I got some laptops in; 3x Thinkpad 600 laptops (a 600, a 600E and a 600X) with various faults. Also a really cool 486 laptop with a DSTN screen. The hard drive was dead and the screen hinges were phyically destroyed (all the screw mounts cracked off so the screen flopped open & closed). That was fixed with some thermo plastic stuff to rebuild the screw mounts for the hinges. I was going to fix it more properly but this works surprisingly well, the hinges work again 😀
This PMD-5500 laptop is really cool since the screen can flip around like Creepingnet's NEC laptops, just without the touch screen. This is my favourite 486 laptop so far, no L2 cache, but it's got an Intel 486 DX4-100, an 11.3" DSTN screen that is in surprisingly workable condition and a soundcard with a Game/MIDI port. It's 60mm thick, one phat laptop!
The CMOS battery needed to be replaced, a VL2330, because the laptop wouldn't boot with a flat CMOS battery. The original battery wasn't holding its 3v charge anymore, but I'm super happy I had a replacement in the flat 😁
It's got a temperature controlled fan on the processor, so mostly it's nice and quiet 😀 And the guy that made the page for the PMD-5500 laptop was kind enough to scan the manual, which has solved a lot of mysteries.
