Actually, the first HP _handheld_ with a card reader was the HP65, which came out a couple of years before the HP67. I have both machines, and they're very nice :-) I have a _few_ cards, but they're not up for grabs. I have an HP9100B (a _real_ calculator ;-) that uses them and one day I'll get round to replacing the card reader roller and using said reader again. The machine is perfect apart from that. -- -tony ard12(a)eng.cam.ac.uk The gates in my computer are AND,OR and NOT, not Bill

[HP9100's] Uh-Oh... _Another_ project goes on the list.... Which reminds me. Where (in the UK, preferably) can you buy Magnasee, either as a spray-on stuff, or as one of those little bubble magnifiers? I would like to obtain some for various repair/preservation jobs. What do you know about the circuitry. I think you're right, BTW, based on the info in the manual and the appropriate HP journal, but I wondered what else you knew. In fact, I think it's one clock track in each direction. I suspect the HP65/67 cards also have a clock track on them. I'm pretty sure the HP71 ones do. Should be possible. -- -tony ard12(a)eng.cam.ac.uk The gates in my computer are AND,OR and NOT, not Bill
