Help w/ EPROM emulator

[Eric Aos]

Check the Archives. Right after GMECM got started there was a lot of
talk about doing an emulator. The most complete plan was something with
a dualport ram chip, that could keep talking to the car while it was
being updated by the laptop. A Pic Micro or similar to manage the
writes, and a max232 to interface with the laptop. I've got one
breadboarded right now... just trying to find time to write the firmware
for it.
