Buttoned it up...put it back on the shelf, just waiting for the fan. this morning I came down to the shop and turned it on along with the 8601 and this is what greeted me on the display.
All voltages were fine. I'm just about done with this. I pulled out the counter board, the one with all the IC chips on it. It has lots of replacements. This board (and no doubt this machine) looks like it drove someone nuts in the past just as much as me. When I put this board back in place, It started working.
This is typical for this instrument. Days and days of normal operation...it gets put in service and bang...it stops working. It's just a turkey. I think I'll sell it as non working and wait for another to come up for sale.
