** Replace this message with your line ** I own a trs-80 model 16a, and wish to use the z80 -> 68000 IPC, but have no real useful documentation to work with. I may have enough information to dope it out, with the combined efforts of a teach ref manual + two service manuals + some letters from tandy, but it would clearly take me a great deal of time and effort to do so. So, my request is that if anyone out there has done the great amount of work involved in doing IPC on the mod 16a without an OS, or has written some sort of z80/68000 OS they would be willing to share, PLEASE send me a message. Most of you know tandy, and know tandy's excuse for documentation, so I would venture to say you can understand why I don't wan't to find the bugs in there documentation trying to find out how to do IPC on this thing. All help is greatly appreciated. Areas of most interest: z80 -> 68000 IPC 68000 -> z80 IPC z80 device I/O (ttys, floppies, lpr-port) trs-80 Hard disk I/O + control DMA unit Interrupt controller (special att to the RTC) Anything else you can think of that would be useful to learning more about the machine. This is of course, just a wish list, but if you can fill in any piece, (especially the top two) it would be a great help to me. Thanks in advance.
