    SC/MP Processor Emulator

    SC/MP Processor Emulator

    Emulator of the ancient 8 bit microprocessor SC/MP 2

    Emulator of the ancient 8 bit microprocessor ISP-8A 500D/600D or more common "SC/MP" from National Semiconductor. The download contains all sources plus an executable Java Jar file to start right away. Some SC/MP hex dump examples are provided in directory "/etc" as well. The download also contains unit tests and some helping documentation (also in /etc). You may slow down the CPU operations, displaying the CPUs status register as LEDs, to watch the CPU working with its registers. The emulator also contains a VDU (video display unit) output / ASCII input simulation. There are some demos in /etc. And have a look to the NIBL / TINY BASIC interpreter in the TINYBASIC folder, most of the code is over 40 years old. Have fun, Theo Heinrichs
