Pretty happy. Last year I bought a case to use for a 486 build I had gathered up parts for but to get a case I ended up with most of another 486 machine that wasn't functional. I couldn't find out the exact manufacture of this board but it is identical to the 486 vla models I have seen from multiple manufacturers like seritech. It's a vlb board.
I finally took a look at it this weekend. Found a bunch of bad radial caps, the battery had been removed but it had already leaked. I neutralized the acid and washed the board. My parts came in the other day so I replaced all the bad caps and got it to boot but no keyboard. Yesterday I managed to track the keyboard problem to a bad trace for the keyboard data pin and did a test repair to confirm. I bodged wire from the bottom of the keyboard connector then brought it back to the top of the board where I exposed the trace and attached it. It is now fully functional. I'm pretty excited. First successful repair. I'll be removing the keyboard connector once I get a better desoldering setup and then clean everything up better and do a nicer looking repair.
It came with 256k cache 8MB ram and an Acer L50 vlb io/VGA card which has 2 ide channels, floppy, serial, etc, and it's video is a Cirrus logic cl-gd543x series card. Which all is fully functional.
