once this was rectified they all powered on with the 11 P powerup display.
if you have a battery on the motherboard, it may be low, and the memory may be corrupted,
you could try removing the backup battery and let the system totally power down for a few minutes, then re-connect the power supply
if you get 11 P then the issue is to re-load the presets
if you dont have 11 P then i am thinking there are problems in the power supply stage
as asked before, what do you mean by wierd display

Poly 800 mk1 doesnt support sysx dump ( until mk3-) ). May be would it
be similar with tape data loading ?
But I suppose it is not only sound-program lost. It looks like more
serious thing - may be mentioned power adjustment...
