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.

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.

Memory dump

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