Emulate UCSD p-System for IBM PC
To try out the IBM PC version you can use an emulator for the IBM PC (the original one, not a later version!)
An emulator that makes this possible on Windows and Linux is PCEM (https://pcem-emulator.co.uk/).
A version that works is version 1.6 as you can see in the following screenshots.
To try this do as follows (Windows)
1. Download and unpack e.g. in C:/pcem, PCEM, here a local copy
2. Download the ROMS for the IBM PC, local copy here
3. Unpack and place the ROM file in C:/pcem/ROMS/IBMPC
4. Download the IMA disk images and unpack in a convenient location
5. Start c:/pcem/PCem.exe and load the disk images as drive A: and B:
6. Reboot the emulator and wait a long time (for me it took minutes!) to see UCSD p-system appear on screen.
