I decided to make a DiskOnChip board for my ISA retro computer. It's a pretty simple board, the video talks a little bit about the design:
Anyhow, myself and a few others were trying to guess at the purpose of the DiskOnChip. It came from eBay, so it could be out of anything. Best guess so far is that it's some sort of communications device, perhaps an access point or router. The DiskOnChip is running DOS 6.2, has a "PCTCP" TCP stack, and some program called CCUMAIN.EXE which other than being able to see parts of a Watcom runtime in it, isn't really clear what the application does. There's a HEX file as well, which my naive guess would be that it is used to program some bit of onboard hardware. Anyhow, speculation is welcome.
