============= PAGE UNDER DEVELOPMENT!!!================


What is M100 CP/M?

M100 CP/M is an implementation of CP/M 2.2 that is tailored to the TRS-80 Model 100 & Tandy 102. Now able to run the dominant operating system of the 1970s & early 1980s means a huge library of programming languages, text adventures, utilities, etc, can now run on these computers. M100 CP/M is free to download from Installation and Set Up.

In order to run CP/M, these computers need two changes to hardware:

  * RAM needs to be present in lower 32KB region
  * Some form of memory to act as disk storage

REXCPM is the device that achieves this. Developed by long-standing M100 hardware specialist Steve Adolph, REXCPM is a plug 'n play Option ROM board that provides the lower 32KB, plus either 2MB or 4MB of RAM-disk.

This package of M100 CP/M & REXCPM makes these computers a venerable CP/M machine with their small footprint, enviable keyboard, super-fast RAM-disk, long battery life, etc, etc.

Status

  * M100 CP/M is currently in beta testing

Installation and Set Up

Once your REXCPM board is installed & verified by running RXCMGR (REX manager) successfully, download these files:

ModelDescriptionFileRevision
M100/T102Installer/updaterCPMUPD.CO1
M100/T102CPM.COCPM.CO1
M100/T102CPM for 2MB REXCPMCPM210.BK1
[ or ]1
M100/T102CPM for 4MB REXCPMCPM410.BK1


Move CPMUPD.CO & CPM.CO to your M100. Leave CPM210.BK (or CPM410.BK) on the emulated-TPDD.

Issue CLEAR 60000 from Basic. In Main Menu, execute CPMUPD.CO.

Enter the 'Install filename', either CPM210.BK or CPM410.BK. As you have no existing CP/M disk, press 'y' to confirm.

M100 CP/M will install, taking over 4-lines of progress dots... (about 1min). On completion, you'll be returned to Main Menu. If there was a TPDD-error, the program will stop & display error message.

Acknowledgements

I would like to thank those that have contributed to the project:

Steve Adolph - for producing REXCPM hardware (which is a delight to program). For CASS/BCR video output, hi-speed Backup and technical support.

Kenneth Pettit - for VirtualT as this project would have remained a dream if not for VT.

Mike Stein - for alerting me to Geoff Graham's VT-100 Terminal project and for beta-testing.
