When you removed the old socket did you carefully examine the legs of

What did you do to clean off the corrosion? I hope you used a mild acid
such as white vinegar to neutralize the alkaline (base) leakage then
rinse off with water...

What did it do when you had a video card and
keyboard installed? Was
there a beep code?
Black screen, no beeps. I get the same POST code sequence with the VGA
card in as I do without it.
The Dallas chip is probably dead (battery), have
you tried reworking it
with a coin cell?
Not yet -- the chip isn't that old, I'd have thought it would still be
good...
Also, the board packed in after I cleared some corrosion (from an old,
leaky nicad battery) from the PCB and replaced the old dual-wipe RTC
chip socket with an Augat turned-pin socket. Now the board is DOA...
