SC/MP Processor Emulator

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!

The C cross-compiler, written in Java, directly compiles C Code into SC/MP machine code. It follows the classical LL(1) recursive-descent approach and makes usage of the emulator math and I/O libraries.

Have fun,
