Virgil Dupras 1a6a549857 Make the SPI Relay protocol support multiple devices Working on programming AVR chips exposes a glaring omission in my first design of the SPI Relay: not allowing multiple devices make this task hard. I constantly have to unplug my SD card before, plug the AVR chip holder, then play a bit, then unplug the AVR holder, then replug the SD card... My prototype for a SPI relay design is built, but I haven't tested it yet. I need to adapt the code first, which is what I do here. When the prototype is tested, I'll update the SDC recipe with a new schema.		3 年前

RC2014 emulation

This emulates a RC2014 classic with 8K of ROM, 32K of RAM and an ACIA hooked to stdin/stdout.

Run make to build.

Usage

Run ./classic /path/to/rom (for example, os.bin from RC2014's recipe). Serial I/O is hooked to stdin/stdout. CTRL+D to quit.

You can press CTRL+E to dump the whole 64K of memory into memdump.
