Hi all,

I have a good offer for that 286 board (see attach). Board is in the pretty good working conditions - at least BIOS is functional.

The question is - which manufacturer? Anybody familiar with that board? Unfortunately, I didn't find any similar on the retroweb. Also I can't see a battery socket on it - I have only guess that it is soldered on a back side somehow.

Any details would be much appreciated.

Thank you.

It probably had external battery connected to the headers to the right of power connector.

There isn't much going on with this or similar 286 boards. If it runs, it's OK. I don't see a reason for much more info.

Looks very close to this one with some sockets populated differently...

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
