We have created a printer interface card (based one the last rev of the
M8571 plus all relevant ECOs) for an LP20 in the front end of our Tops-10
system (a DECSYSTEM-2065). ?It turns out that the other cards in the LP20
are not entirely defect free, so we need to hook up a logic analyzer to
see where things are going wrong. ?We have no Unibus extenders, so we can't
do things like cool suspect delay pots.
We'd really prefer not to have to try building these. :-)
