;	The following code is supplied to customers who
;	purchase a hard/floppy disk system from CompuPro.
;	The intent of the following code is to illustrate
;	how to create a CBIOS for the user supplied
;	CP/M 2.2.  In order to actually assemble this
;	source, the Sorcim ACT assembler is required.
;	The following CBIOS was developed and
;	tested using the following hardware components.
;
;	CompuPro IEEE 696 Floppy Disk Controller.
;	CompuPro IEEE 696 chassis and motherboards.
;	CompuPro IEEE 696 Dual Processor board.
;	CompuPro IEEE 696 RAM 20 boards (2).
