According to my Horizon manual, "... can be used in any standard S-100 bus computer and will operate in conjunction with nearly all other S-100 bus boards." If you need docs or a schematic let me know. I have used a Morrow DJ2 with my Horizon quite successfully.

I have a weird question. Could a Northstar MPU-A be used in a normal S100 bus chassis with other cards to provide console, disk, i/o, memory functions? If no, why not? If yes, what issues can arise from doing this? The reason I ask is that I have a nice clean empty TEI chassis, a Northstar CPU cards, some memory boards, an SMB multifunction i/o card and a Disk Jockey 2D. I'm sure the thing would end up being fairly weird, but I don't care about that. Just exploring ideas for misc hardware sitting around my basement. Anthony Clifton
