Has anyone seen this type of cache connector before? I would normally expect to see the static DRAM sockets on 486 motherboards but this one has a weird connector almost for some type of module.

Let me know what you think.

I've seen that layout before but it wasn't cache it was a main memory upgrade for a PC-98 series. (Sold in Japan only.)

I found another person who appears to have a very similar motherboard with just some variance with the onboard memory.

Has quite a few pictures on his site. Didnt see any information on what type of module was needed for that cache socket though. 🙁

Like this, but the ones I had were two decks with the RAM soldered onto the PCB.

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 which makes sense. If anyone stumbles across any info about this board or has any advice on how to locate it I would appreciate any help you could provide.

Thanks in advance.

Do you have the BIOS string?

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.

I hate to revive such an old thread, but I recently acquired an Acer Acros with similar cache sockets. Has anyone seen these types of sockets before? I was hoping to add some cache.

EDIT: did some poking around and came across some documentation on a similar board that has similar labeled cache sockets.

Unfortunately these proprietary cache boards will probably be almost next to impossible to find.
