Here is a nice Intel iSBC 88/25 MULTIBUS Single Board Computer

It has the FPU option installed (with a D8088 and C8087-3) as well as the EPROM Expansion (Complete with Extended Temp w/ Burn in screening LD27128 EPROMs)

Board has some minor corrosion it appears on the left side but otherwise is a nice board.

$49 and its yours

I'm interested, but can I see the corrosion you're mentioning? The pic resolution is too low.

Documentation at http://www.nj7p.org/Manuals/PDFs/Intel/143847-003.pdf and https://archive.org/details/bitsavers_inteliSBC1HardwareReferenceManualOct81_2990758

Now if I could find the RAM expansion module iSBC 302; that would increase the amount of memory available up to a whopping 12kB. Smile

(or maybe I can make one, since the hardware reference manual above has full schematics of the board and the EPROM and RAM expansion modules)

I really like that they have full schematics, makes mods/repairs simpler
