Thanks... I'll have to recheck the manual, I guess I missed it. Now
I have to figure out what 'off' means... shorting pin 4 to what other
pin (shorted low or high).
I'm thinking of trying a KA630 as a coprocessor in a qbus pdp-11
system.
The KA650 manual mentions using the same board, but it says that only
the off-off configuration is supported. I wonder if the KA650 can
be a co-processor as well... But then, the KA650 doesn't have on-board
memory.
