The early Z-158 CPU boards have been infamous in developing intermittant
parity problems. All chips on these boards were socketed and there were so
many mods that there is a rats nest of wires on the back of them. Most of these
parity failures defy locating because they are so erratic. Sometimes reseating
the chips helps. Best solution is to exchange the board with ZDS for the new
version. The new version card is P/N 181-6792. One old version is 181-5857
and I believe there is one other part number that is even older. You can
exchange the card through a service center or through Heath parts for about
$200.00.
Hope this helps.
