HP-110 Plus laptop power supply specs?

The HP Portable and Portable Plus use the same power supply that's used for most of the HP-IL devices. It's also used for the HP-71 and 75 calculators and the rechargable battery pack for the HP-41. It will also operate the HP-91, 92 and 97 but their ORIGINAL power supplies are slightly different. In the US the charger is a HP 82059 but they also make different versions to match the AC voltages and outlets in most other countries. The output on all of them is 8 VAC. I don't remember the current but it's about 150 Ma IIRC. Look at <http://search.ebay.com/HP-hewlett-82059_W0QQsofocusZbsQQsbrftogZ1QQfromZR10 QQcatrefZC6QQsatitleZQ28HPQ2ChewlettQ29Q20Q2082059*QQcoactionZcompareQQcopag enumZ1QQcoentrypageZsearch> for pictures. The batteries in the PP and PP+ are a pain. They're lead acid and they are individual cylinders. So if you let them run down for very long, it will ruin them and they're not an easy style to find. IIRC they're X size which is slightly larger than standard D size. Joe At 04:23 AM 6/28/04 +1100, you wrote:
