Schematic for RAM Disk Board?

Postby tranter » Mar Mon 10, 2014 10:40 pm

Unlike the rest of the Altair 8800, the CD doesn't include a schematic for the RAM disk board. Could that be made available? I don't have a pressing need for it, but I would be interested in seeing it to better understand how the hardware works.

The T* utilities (TREAD, TWRITE, etc.) also don't seem to have source code available for them. I know they are written in C - I'd be interested in getting the source code and possibly modifying it to add new features.

I used the BDS C package for the "T" utilities. There is a small library of routines common to the utilities and also a few assembler routines to do direct RAMDisk I/O as the overhead of using the C runtime library was just too much of a performance hit.

I've been meaning to make the sources available, but I'm currently away from home until late next week. When I'm back I'll see if I can get the RAMDisk image that has the sources zipped up and posted.

Garry: Did you get a chance to dig up the sources for the TUTILS?

Not yet, but I think I'll be able to free up some time, hopefully this week. I apologize for the delay, but things have been quite hectic this last month or so.
