Thanks for all your advice....I've got my plan together....
What I've done thus far...
1) Study the schematics
2) applied only +5 volts to the board, isolated DMAGO (vector state
machine)
3) Saw a lovely watchdog bark! (woo hoo - signs of life!)
4) Pulled ROMS (version 2) and checksummed them :
Rom B1 checks to B2A4 - Appears wrong.
Rom F1 checks to 0000 - Language chip ? (where are the
vectorlist archives when you need them!)
All others check to the proper values.
So, I will burn up a new B1 (2716) and go from there!
F1 is the language chip right? (trying to remember Clays post of last week)
Maybe I should burn me a new one of those to be sure.
