Re: Booting problem - is this unit dead?
I suspect this might be a power supply problem, but what's the correct method for measuring the voltages? The lead batteries were very old and I have removed them. I suspect this unit has never been serviced. I'm doing this just as a hobby and this area doesn't even have landlines anymore (most of F...

DECM4 sync problem on 4200e 3.0
Hi I'm trying to make this old unit to work and it seems to be ok, but this DECM4 board is unhappy and just keeps the red led lit. AC board has the X4 jumper installed and still no luck. I do not have CKIBS or a board to mount it. What i have is this: CM, AC, DLC8 (3boards), SOTO4, SLC8 (2boards), T...
