So, recently picked up a Texas Microsystems N286 SBC. Neat looking little SBC with a harris 286-16mhz and a 20mhz crystal.

Anyway, spent a long time trying to bring it up. Eventually I dumped the BIOS.

Well its not a normal PC bios, it has a custom BIOS from what looks like a colour printer. The BIOS entry points, it has only the reset one, everything else is different. Its a 128kb bios. It doesnt boot up with a screen or do anything you would expect.

Basically, anyone have an N286 they can dump the bios from or a file of the bios??
