If anyone is interested in old GPIB adapter hardware and has a USA mailing address, I can offer for free:
- HP 27209-60001 GPIB 8-bit ISA card, or
- IOTech Micro488/EX Bus Controller (this is a bi-directional RS232<-->GPIB gateway), w/power adapter and manual
Either (or both, if you can use both), would be for the cost of postage on a USPS flat-rate box. You would email me a label.
Either can be used to do the cal backup, and communicate with other GPIB/HPIB/IEEE-488 equipment. They're not doing anything here except collecting dust for years. Please contact me off-list if interested.
