I will check this out, hopefully this weekend.=A0 Out
of curiosity, is ther=
e an extender or some other way of probing these boards while powered up?=
Extender boards are very rare. JHP never intneded thse machiens ot be
reparied to compneent-level in the field so there was no official set of
extender baords. And they carefully put the conenctors for different
boards in differnet positions so you would really need an extender for
each board.
However, there are several workarounds. The PSU will run with nothing
else in the machbine -- and with the other boards removed it's easy to
get to the track side of the PSU PCB. For times when you have to work o
na board with those around it fited, what I do is to solder a few wires
onto lilely testpoints, put he board in the machine and porbe the free
ends of the wirs.

By the way, does anybody know the number of the mating plugs to make a cabl=
e for the 9866A printer?=A0 It looks like a 19-pin cannon connector.=A0 The=
se seem expensive, so at least it would be nice to be confident I'm seeking=
the right model.=A0 Any info on plugs and cable would be welcome.=0A=
It _is_ a standard connector. I haev seen it described as a 'MIL-C-26482'
connector with a size 14 shell and 19 contacts. They are still available,
for example Farnell sell them in the UK), but they are NOT cheap.
If you have the machine and the 9866A printer you basically have 2
options. Bite the bullet and buy a couple of the plugs and wire them
together. Or wait for a cable to turn up on E-bay and hope it doesn't
sell for more than the cost of 2 plugs. The formwer is generally easier...
