I purchased an Intel 310 chassis from eBay in March 2013. This board contained an iSBC 286/12 SBC, a Matrox processor board, and several boards marked as Flight Simulator boards. I had no use for the Matrox or Flight Simulator Boards and traded them for two operational iSBC 208 FDC boards.
The ROMs appear to be standard Intel boot ROMS. There are 2 27256 EPROMS. Here they are: U46-176024-001.bin. U79-176024-002.bin.
