I have still to check my unit but I am afraid PROMS are soldered... I hope to
have some time over the weekend. Sorry for delay <grin>!
BTW, I also have an 'A' (working) and a 'B' (parts unit) and I can tell for
sure
that firmware is the same, because I swapped digital boards among them and
unit
works fine ;-)!

That's a pain:-(
I'm certainly not set up at the moment to remove ICs from PCBs without risk
of damage and don't have any means of reading the Proms in circuit.
I'll still take a look anyway if I can get access to the units.
