============= 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:
| Model | Description | File | Revision |
| M100/T102 | Installer/updater | CPMUPD.CO | 1 |
| M100/T102 | CPM.CO | CPM.CO | 1 |
| M100/T102 | CPM for 2MB REXCPM | CPM210.BK | 1 |
| [ or ] | 1 | ||
| M100/T102 | CPM for 4MB REXCPM | CPM410.BK | 1 |
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.
