HP Extender Cards, a pair; for just $29 !
These
HP Extender Cards are like new. I don't recall which instruments
they fit. It's possible that the 1900 series Pulse Generators is
one...but there are likely others of that era which used the same
connectors.
NOTE: added 1/24/09....Dave at Artek thinks that known uses for the 5060-0049 extender cards are, among others
> 5326A/27A
> 105B Quartz Frequency Standard
> 3570A
Chris Trask suggests that the 3330A is also a fairly definite possibility.
The HP part number is 5060-0049, as shown in the picture here....

Response
Time: We live in the mountains now, and my wife gets into town a
couple
times a week for mail and groceries (I don't drive much any more,
since my vision is failing). Expect about a week between
receipt/clearing of your payment and when the carefully-packed
instrument is dropped off at the UPS terminal or Post Office in
Medford, Oregon.
