CP/M Newbie Questions (Emulation and more)
Jack Strangio says: ...My hardware systems have long since gone. My first system was a North Star Horizon which I built from a huge box of components over about 40 hours of soldering and about another 10 hours of mechanical assembly. This started off with North Star DOS and then later used CP/M. Then followed a short-l

ANN: DX-Forth 4.00 for CP/M
Ed says: ...Thanks. I implemented this in the 90's and no longer recalled the source of the information (DRI ?). The optimization might be noticeable if the hardware was fast e.g. memory-mapped video. In my case it was only a matter of 6 extra lines of assembler.

My Sperry UTS-30 CP/M system is now functional again

These have been in storage for over 10 years because they were in-operable. The keybo

chaining submit files
John Elliott says: ... I wonder if the three were separated because of limited disk space on the drive used to build; each .SUB file builds a number of programs on drive J:, and then deletes the intermediate files. Under CP/M 3, SUBMIT files can be nested, but each nesting will load its own copy of the GET RSX, occupy
