Today I have been having a go at getting my "untested" FIC 486 VIP IO2 working... It doesn't!
First of all, there's no resistor pack for the CPU - thanks to this thread - I worked out that mine are 8 pin, 4 pair, 0 Ohms resistor packs, verified with the muitimeter using the resistor pack for the keyboard controller settings. Then I remembered I'd bought a kit of breadboard jumpers, which fit nicely there instead, since I can't find 0 ohm resistor packs for sale.
Turning it on was a disappointment, the PSU, CPU and memory are all known good on other computers, but the ISA diagnostic card just shows "--,--", indicating there's no life.
This is where I'm very glad that I bought a TL866 programmer - reading the NM27C010Q BIOS chip, everything from 0x0000 to 0x7999 is blank, with some references to an NCR53710?
I tried to program it and that failed on the verify stage... is it broken?
Then realised it's a UV EPROM, not an EEPROM, so right now I'm waiting to see if my UV torch is enough to clear it 😁
Then see if it boots at all, fun!
I'll add some pictures tomorrow, maybe make a thread about this pesky motherboard. My quest for a 486 board with PS/2 mouse and VLB continues - my Asus PVI 486 SP3's VLB port doesn't seem to work and although it registers the L2 cache on boot, it's not using it 🙁
edit: bleh, my little UV torch didn't do anything, time to sort out a proper UV light instead, I assume it requires the dangerous to humans frequency rather than the sort you use to make white things glow?
