From: Ronald G. Fowler Re: CP/M Disassembly Date: 7 March 1984 02:30-EST Didn't mean to imply in my previous message that it was I who was doing the disassembly; actually, it's Clark Calkins (C.C. Software, 2564 Walnut Blvd. #106, Walnut Creek, CA 94598) -- he's the guy who sells MP/C, a disassembly of CP/M 2.2 (reviewed by Pournelle in the Sept. 83 Byte). He sent me the CCP, and figured he'd have the banked and resident BDOS disassemblies in early March (at the time, he was about 80% through the disassembly), so I should hear from him Real Soon Now; he plans to sell the whole package for $55, which has to be the bargain of the year (his 2.2 disassembly was $29, the bargain of last year). The way this thing works is that you have your CCP.COM, RESBDOS.SPR, and BNKBDOS.SPR files on the logged-in drive, and his program disassembles them (using encrypted data files he provides with the package). Thus, he doesn't violate DR's copyright, since you have to have the package to get the disassembly. You might want to give Clark a call, and see if he's selling the package yet (tell him I sent you). --Ron  .
