Wordstar Emulator 64 Bits Host Environments

It can be built both on 32 and 64 bits host environments and should be easily portable to other platforms.

RunCPM is fully written in C and in a modular way, so porting to other platforms should be only a matter of writing an abstraction layer file for it.

Wordstar Emulator Code Modules Should

No modification to the main code modules should be necessary.

RunCPM emulates CPM 2.2 from Digital Research as close as possible, the only difference being that it uses regular folders on the host instead of disk images.

Making changes, recompiling MicroMumps and loading it onto a regular CPM emulator via a disk image every time I moved a bit forward on the restoration was becoming too time consuming.

So I decided to write something that would allow me to run the executable right away after making any modifications.

RunCPM then evolved as more and more CPM applications were added to its compatibility list.

It can also be built on the Arduino IDE and even on DJGPP for DOS.

If using the Arduino DUE, RunCPM also needs a SD (or microSD) card shield to place the CPM files in.

Some ESP32 and STM32 boards may need external SD card adapters.

It is theoretically possible to run it on an Arduino which has enough Flash (at least 96K) by adding external RAM to it via some shield, but this is untested, probably slow and would require an entirely different port of RunCPM code.

The name of the package providing it depends on the Linux distribution.

Some are named ncurses-dev, some ncurses-devel, so Google is your friend for that.

The 64K version CCPs will provide the maximum amount of memory possible to CPM applications, but its addressing ranges are unrealistic in terms of emulating a real CPM 2.2 computer.

The 60K version CCPs will provide a more realistic addressing space, by keeping the CCP entry point on the same loading address it would be on a physical CPM computer.

Other amounts of memory can be used, but this would require rebuilding the CCP binaries (sources available on disk A.ZIP).

The CCP binaries are named with their file name extensions matching the amount of memory they run on, so for example, DRIs CCP runnin on 60K memory would be named CCP-DR.60K.

RunCPM looks for the file accordingly, depending on the amount of memory selected when it is built.

This favors the porting of even more different CCP codes to RunCPM.

This also requires that, starting on version 3.4, new copies of the master disk A.ZIP, ZCPR2 CCP and ZCPR3 CCP (all provided here) are used.

The support of non-user-area disk folders has been dropped between versions 3.5 and 3.6, so if you are running on a version up to 3.5, please consider moving to 3.7 or higher but not before updating your disk folders structure to match the support of user areas (see below).

This is the user area 0 of disk A:, extract the contents of A.ZIP package into this 0 subfolder.

Switching to another user area inside CPM will automatically create the respective user area subfolders, 1, 2, 3.

Subfolders for the user areas 10 to 15 are created as letters A to F.
