Default Retro computer homebrew: Orton SC/MP emulator with NIBL

Hi All,

Well, here's my latest SC/MP emulator. This one approximates the SC/MP at chip level, i.e. you could build a system with real SRAM, EPROM, I/O ports etc.

It includes a boot facility which copies up to 4k bytes into low memory. Thereafter this memory is write protected so behaves like ROM. I use this to load NIBL into a 32k byte SRAM.

Nice - I really must learn about managing PIC chips as this seems a great way to play with NIBL on real hardware.
