Productive day today. Managed to finish the 386 system I've been tinkering with for a while. It's become a right little beauty - as bare as I got it (RAM, CPU and I/O only, leaking battery and filthy case) as full it is now:
- cleaned the battery damage, in the end only lost the uppermost 8b ISA slot to corrosion.
- replaced the battery with an external 3x AAA NiMH holder stuck at the lowest point in the case.
- cleaned the case thoroughly
- added 121MB HDD, CDRom drive, Intel EtherExpress 8/16 NIC and Soundblaster 16 Value CT2770.
- got all that stuff set up and installed MTCP - yep, this old beast is on the internet 😜
As I'm not keeping it, that's as far as I'm taking it, but given the CT2770 has an IDE header, the CDRom could be moved there, freeing up the slave position on the regular IDE controller for a second HDD. And as well as good performance and great drivers, the EtherExpress 8/16 has a nice ROM socket that could take an XTIDE.
After that I took a 486 that was booting but not detecting any keyboards. Removed the motherboard battery, cleaned the inevitable mess and gave the area around the keyboard connector an extra clean too. Once it's dry tomorrow we'll see what's going on.
Finally re-capped an MSI MS-6340 (Via KM133 chipset, from a Packard Bell iConnect). After working on 1990-era leaded solder, it's a shock how hard (in every sense of the word) the RoHS stuff is again. But that's just a temporary irritation. Now it's sporting flashy new Nichicon, Rubycon and United Chemicon caps. Haven't had time to test it yet.
