30 July 93 Chuck - Enclosed are the three disks we discussed. The CP/M System Disk has an early version of CP/M 2.2 and boots on a Kaypro IV that I have here. The SWP Co-Power Loader Disk contains a later version of CP/M. If it does not boot - and the other one does - you will probably want to Sysgen that system to it. The MSDOS Disk should require no changes. Hope it works for you. Let me know, please. - don
