This boot code and bios allow building a CP/M system that boots and runs on a Cromemco 16FDC.  The code is pure 8080, there is no Z-80 code and it assembles with MAC.  Tested on 7/5/2004, these do work.  The bios only supports 8" drives at this time (there are fragments in the code for future 5" support).  It also only supports single density.

This probably runs also on a Cromemco 4FDC and 64FDC.  It also probably runs on the CCS floppy disk controller, which was architecturally almost identical to the Cromemco controller, to the extent of being sofware compatible.
