Hi Jim, Yes there is a special LaddieAlpha that runs at 76800. John of course owns that. Right now the only software I have that makes use of the 76800 modified TPDD routines in M100 is the RXCUTL software.
Having said that, I've not touched it in 2 years, to either test or use. Should still be ok. as a reminder this is the speed improvement. Helpful. Backup/Restore processes can take some time; use this table for guidance. *Process* *Memory size* *Duration* *Duration* REXCPM either 19200 5:20 min CP/M 2MB 19200 13 min CP/M 4MB 19200 33 min REXCPM either 76800 2:10 min CP/M 2MB 76800 5 min CP/M 4MB 76800 13:15 min On Fri, Feb 24, 2023 at 12:59 PM Jim Anderson <jim.ander...@kpu.ca> wrote: > > -----Original Message----- > > > > Did you ever finish whatever it was you still needed to do for rexcpm? > > > > I don't remember what the problem was supposed to be by now, but I > > remember to keep watching for some update to either cpmupd or to the > > disk image every time I reload my rexcpm, and I only know that the files > > haven't changed. > > > > I guess for that matter the question should be "What was that problem > > supposed to be again?" > > Another chime in from someone who is still around but lurking :) > > I didn't want to bring this up because I have my own unfinished project I > feel guilty about, but I will answer the question.
