Spitballing… could an Arduino or RaspberryPi or some powerful PLC ever
be programmed to substitute for the StrongArm? I could see the core
code blazing, but having its serial communication throttled
appropriately.

Could the SA-1110 be added in and have the Arduino or the Pi or the
PLC be the translator sitting between the 1110 and the SA-110?

…or would the best approach be about asking Apple nicely enough for
the ROM source?
