Basically, via emulation for now. I got a dump of the PROM (U114) from Phil Bennett and wrote a little C program to exercise it, while emulating the 12 MHz clock source.
In the (near) future, I hope to get a logic analyzer capture from the real hardware. Hopefully it is very close
UPDATE: Warren Ondras made a capture for me from real hardware last night and I added it to my blog. It matches my emulated version perfectly
