Have had this for years but never found a manual. Is it very different from the Concorde-V. Has 30pin simm sockets where the -V does not. It works well with the 1Mb dip ram but want to add the simms and a mathco but cannot decipher the jumper and switch pack as they mostly lead to 74244 and 74245's before rerouting to the NEC DF12013 chip.
Sorry the full board pic is not better, bad light makes bad pictures.

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

Found one link but is thru google.books and requires permission to open it. Guess I need to start mapping the board out...

In the mean time, PM me that link and whatever we find can be added here:

bios dump is welcome too.

Ok sure ! I figured out some of the SW1 settings and also found some memory utils for it though untested but from DFI archive for the 286 Concorde series iirc.
Will have to pull the ROM and read it (not sure why I did not already but it has been near a year since I played with it wow time flies when you get old 🙁 )

I have that board, mine currently has no DIL chips installed and switch block is set to all on apart from 6 and 7 off, and I believe it was booting with 2 SIMMs installed like that. No Co-Pro installed, jumpers in the block set the same as yours. Mine has same silkscreen with no additional clues.

Edit: DIL RAM chips that is, other socketed ones are populated apart from 287

EditII: Ah found where the pic of it was, not the greatest beauty shot but bottom right here... download/file.php?id=115198&mode=view

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