It doesn't appear to have a traditional BIOS string visible on boot as I would expect. Here is a screenshot of the POST display and a pic of the BIOS Chip.

Here is an additional shot of the make/model, etc. I am not having any luck finding any specs or manuals for this acer model online. In the link above the other user with the same motherboard said that their model was an Acer Power so it looks like they used the same motherboard in different models …

Received the replacement caps and just finished installing them. VIOLA!!. The old girl lives again!! I really appreciate everyone who helped me out with this issue. You guys/gals are the best!!.

I did find an old technical reference manual for my Tandy 4000 online here: ftp://ftp.mindcandydvd.com/pub/tvdog/other_tandy_x86/4000trm.pdf On page 150 of the pdf there looks to be a schematic for the AT bus which looks like what I may be dealing with. In the lower right hand corner there appears …
