Hi my name is Diego, im from Brazil.
There are some time that i dont practice, sorry my bad english.
Im a reader of this forum for a long time, but this is my first post.
I got recently a 386sx40 motherboard, but i cant find any information about it.
Does someone recognize this board?
Thanks!
Hi Diego, welcome to VOGONS
While I can't help you identify the board, that area near where the battery was located seems to require immediate attention due to leakage of battery acid.

Hi shock.
I removed everything around the battery, cleaned and patched a couple of lines.
Its not beautifull, but its clean.
I noticed that there is printed "Opti-291" on the board.
A google search led me to this page: http://www.opti-inc.com/my_html/part_mb.html
On were there's a link for FCC-Code searching: http://transition.fcc.gov/oet/ea/fccid/
If there is any FCC-Code, you can try to look it up....

I noticed this 386SX board has Cache (64k?). Very nice.

Hello there, Diego!
What's the weather like in Brazil? Today it's warm and sunny in Siberia, only 10°C below zero 😀
You got a nice board there, and good job on cleaning up the acid.
You might want to check out this database, a lot of boards are documented there: http://museum.ttrk.ee/th99/
This motherboard support up to 64K cache and 16MB Ram. Appear to be a nice board, i'll make some benchmarks.
idspispopd its very similar , thanks a lot.

OMG, that's hot!
Cache does wonders on a 386, and this must be the fastest 386SX-40 board around here at least. It's interresting how this board features only 2-chip bank due to 16-bit SX bus. I imagine it being a huge pain in the butt to buy three of these chips in a store, as they were used (and probably sold) in sets of four. Correct me if I'm wrong 😀
