Port of Grant Searle's MultiComp to the MiSTer.
Updated by S0urceror to use MiSTer image files, use all 4 machine types and have the MiSTer UART connected to serial interface 2 of the core. The latter allows to use the core remotely.
The MiSTer OSD allows the access to four machines:
You can now use both an external SDCard and/or select the image file within MiSTer. Whatever you like.
For convenience you can use the Multicomp FPGA - CP/M Demo Disk from Obsolescence Guaranteed: http://obsolescence.wixsite.com/obsolescence/multicomp-fpga-cpm-demo-disk
After you have flash the CP/M Demo Disk to the SD Card you will have to use the secondary SD Card on the MiSTer on I/O Board: https://github.com/MiSTer-devel/Main_MiSTer/wiki/IO-Board

PLUS my additional implementations here (making it version 4.7b):
HEX$(nn) - convert a SIGNED integer (-32768 to +32767) to a string containing the hex value BIN$(nn) - convert a SIGNED integer (-32768 to +32767) to a string containing the binary value &Hnn - interpret the value after the &H as a HEX value (signed 16 bit) &Bnn - interpret the value after the &B as a BINARY value (signed 16 bit)
