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.
