I am curious how I'd attempt to use one of these.
Any thoughts?
I'd start by dumping and disassembling.
(If you need something to find out where in memory they are, I have
a register discovery program that sweeps the I/O page and lists all
locations that respond. It's probably 173xxx though, that's the
DEC-allocated spare for ROM.)
