41c with 785 registers?
I am rebuilding a HP-41 from scrap parts. I have gotten it to power up and it shows "memory lost" and immediately goes into program run mode. Holding down R/S shows "00 REG 785"

Has anyone seen something similar to this or can shed any light on this issue? My gut feeling is fried CPU board.
