Re: AC Adapter for old HP Calculators Message #2 Posted by John Ioannidis on 4 Nov 2005, 11:01 a.m., in response to message #1 by Bruno
No, there isn't.
Assuming you don't want to buy the real thing on ebay, your best option is to rebuild (if necessary) your battery pac and keep charging it on an external charger. Another option is to get a *regulated* 3.6V power supply capable of sourcing at least 1A and connecting that to the battery contacts (inside the battery compartment, NOT the AC adaptor socket.
Remember that you MUST NOT run the card reader on AC adaptor power only; you need a charged battery in the calculator for that.
