Now, when I said "not critical" it was in the context of using a different
processor, not of controlling the hardware via registered mail... :-)

The USB link you use is adding a lot more latency than a directly attached
microcontroller would suffer.

Those of you wanting to look at the firmware can use the "PyRevEng" project
I have made on github.  You just need a HP5370B rom image (google is your
friend, if your memory fails you) and a python runtime and you're all set.
