The battery is Nicad and seems to hold a charge, lets see after some hours of charging.
What about that ext io module to access the whole 720 k of the floppy, is this thing obtainable or should I forget.

Hi Erik,

What do you mean by "the right printer cartridge"? From the HP Computer Museum:

Quote:The original ink cartridge for the ThinkJet printer was the 92261A. This cartridge had to be used with HP's special JetPaper to achieve an acceptable result. In the following years, additional ink cartridges were introduced to work with the ThinkJet and QuietJet printers. The plain paper cartridge was the 51604A. Single color cartridges were also introduced and required HP's JetPaper to achieve an acceptable result: 51605R (red), 51605B (blue) and 51605G (green).

The ink cartridge in the pic looks like the 51604A which is the modern one. Note, the paper included with the printer is the now hard-to-find inkjet paper and standard pinfeed paper, for use with the 51605A cartridge, in boxes smaller than 2500 sheets is also hard to find.

The printer does use a battery pack comprised of six sub-C NiCd cells. If you need to refurb the pack you can use either NiCd or NiMH cells with tabs.

Regarding the XIO module, I'm a 71 guy so I'll pass on that one, but XIO modules have sold recently on eBay. One included a 41CX.
