After removing the PROMs from my RX02 controller and attempting to extract
their contents, I've discovered that the Unipak for my Data I/O System 19
has a failure. It's returning Error 70 whenever socket 6 is accessed.
Of course socket 6 is the one the 7643 PROMs need to go in. Error 70
means something's wrong with the "bit supply".
Data I/O built a "calibration extender", P/N 910-1521 that was used
to enable probing of the Unipak while it was raised up and out of the
main chassis. It would sure make it easier to work on this thing if I
had access to said extender.
Does anyone have one they would be open to loaning out for a short while
while I attempt repair of this unit? Or, better yet, does anyone have
one they want to sell/trade?
