Power for HP82162A Printer and HP9114 Disc Drive

Posted by Philip Isaac (Canada) on 3 Mar 2009, 12:02 p.m.

When I found I could no longer get battery packs for the thermal printer and disc drive I have in the IL loop with my HP41CX I wired them to run off a 6 volt tractor battery (from my 1957 JD420 crawler).The system works well. The HP7470A Plotter, also in the loop, uses 110AC so doesn't need the battery connection.
