- Some years ago I started to write a emulator for Z80 based
- CP/M systems (I have still a PC1715 which was certainly the
- most used computer in the GDR). But then I did not know why
- I should continue, so I left it.
-
- Actually the processor is nearly full emulated, except
- interrupt handling (it is not needed for a CP/M emulation).
- Only very few BDOS and BIOS calls are implemented, and no
- disk handling. But Turbo Pascal, a Basic interpreter and some
- other programs that do not necessarily need disk accesses run
- without problems. And well, it thinks it has a German
- keyboard, so z and y are swapped on english keyboards.
-
- I supply it with the basic interpreter, so you can play a bit
- with it. On a A3010 it should reach nearly the original speed
- of a 4MHz Z80, and on a Strongarm it is about as fast as a
- 100MHz Z80. To run it, type cpm:basi/com if the program asks
- you for a name. If you want to leave, type "system".
-
- I only plan to use this program for emulating the environment
- for the Z80 cpu I will use to control my self-built amplifier,
- but if you feel you could need the source, feel free to
- contact me via email.
