Just curious, is there by chance a removable eprom or other programmable
device on these boards?

Assuming a fairly verbose scpi like command interface, I've occasionally
had luck reverse engineering a command set by looking through an eprom dump
for a list of commands?

Also, does this by chance respond to the standard scpi commands like *IDN?
and *TST?
