I've checked the wiring of these "proprietary" slots; first half (closer to rear) seems to be ordinary 8-bit ISA bus, but second half has nothing in common with 16-bit ISA. I am not surprised: there are not so much contact lines to put additional 16 bits of data bus, at least additional 8 bits of …

I've spent plenty of time working on XT in 1990s, so fed up enough (at least for a moment). On the other hand, Pentium with its PCI and DIMMs is "too fresh" for me. So, 286 and 386, perhaps a bit of 486, meaning the "era" is 1986-1995, DOS + DOS4GW.

Corrosion is cleared, of course. I had to desolder one ISA slot in order repair several thin traces. Not sure about the KBD, did not check the connector itself (as I expected the board won't start at all) and hope it has just to be re-soldered. BTW, there are two black wires on the back that seem to …

Merry Christmas, guys! I've got such a board, which has VIP TAM 20-II (maybe 11, not ii ?) model on it. Corrosion damage supplied, of course :( Backside label 89'48 says it was made more than 33 years ago! Managed to get a memory board VIP I301020 (also EMC/8M sign on it) which carries 72 M5M42256AP …

I dont plan "USSR-themed" PC, especially with this, US-born, hardware. However, I was working on soviet ES-1840 (8086, 512KbRAM, 2x5.25FDD (720k), NO HDD, b/w CGA) until 1995 or 1996 and this machine did a huge amount of work - documents, educational programming (I was a lecturer) and plenty of …

Mentioning the size - "Athena" is quite small: 39cm (15") depth x 41cm (16") width x 10cm (4") height. I am pretty sure everybody knows Norton Commander. Volkov commander is a USSR clone with some enhancements, I cant remember exact difference between NC and VC actually %)

Hello everyone! Recently salvaged this 1990 PC, which seems to be a kind of IBM/PS2 clone - at least it uses PS/2 mouse and keyboard, 30-pin SIMMs and similar board design. Not an Asian or European clone, though. Motherboard incorporates COM, LPT, floppy and IDE controllers and even a VGA! Never …
