  • I cut the VG 4.0C Serial Monitor down to 1K. The I8251 code could be replaced with M6850 code. I'm not sure if there is enough that can be cut to make room for a MITS boot loader and still leave enough function. http://web.archive.org/web/20110720214308/http:/vector-graphic.info/Documents/40X.ASM W.Tom S.

  • The monitor initializes the serial ports. VG CP/M uses entry points in the monitor. A different monitor would be needed for use with a Flashwriter. The entry points would be the same. I don't think the Microp[olis controller is port driven. The controller is memory mapped. Older configurations exist for systems smaller than 56K. W. Tom S.

  • I just noticed the Bill's MITS controllers sold quickly on eBay. These controllers might be better labeled as 3202 controllers and not DCDD. These controllers used flat ribbon cable for the internal Altair mainframe cables. The external cable was likely a six foot flat ribbon with Ansley blue IDC. I agree that flat ribbon cable should be short. I think short can be somewhere over...
