Micro/Sys CP/M User's guide - several tens of pages, majority source code. Micro/Sys SB8420 dual serial card reference manual -dozen-plus pages,=20 schematics, code. Micro/Sys SB8341 DMA controller reference manual - dozen plus pages,=20 schematics, code Micro/Sys SB8510 Floppy controller reference manual - tens of pages, schematics, code= . Do you not want the 8341 DMA controller? It's not that big. I don't know=20 if the CP/M and 8510 reference use of DMA. The CP/M guide mentions the=20 8085 and Z80, so it's surely CP/M-80. I'll work on these in the meantime. I'll see about Pro-Log hardware.
