Check the cable, if it's not the one you used with the other
serial port card.

Tony,
Thanks for the tips. The card may have bad component(s) but at least it
had not yet been previously repaired when the unit was in production. I
find "vintage" repairs from back in their day are often sloppy and caused
damage. I'd rather have a bad card "as-was" so there is a better chance to
restore today. It seems as if the 1488's go bad on these more often than
1489's.
The original cable, p/n is a 1700004-1 flat cable with Berg connectors on
either end so I had to find something compatible with a terminal instead.
I switched in the same BC03L-10 that I have been using to connect to a
25-pin terminal (with null modem adapter) using a newer DL11-W. (M7856).
