I have an HP GPIO 98622A, Rev B (for 9000 series 300) and an HP 82306A (ISA GPIO for 82300 measurement coprocessor) need a good home. I'll post them on eBay in the next day or so if I don't hear from classiccmp subscribers. Some Info regarding the 98622 can be found at: http://www.tamsinc.com/support/gpio/theory.htm Info on the 82306 can be found at: http://ftp.agilent.com/pub/mpusup/pc/old/vp_gpio.html Let me know if you are interested, Mike
