Re: HP-9x Power Supply Message #2 Posted by Raymond Del Tondo on 31 July 2003, 7:19 p.m., in response to message #1 by Gordon Dyer
Hi,
HP used the nearly the same standard wall adapter for many machines.
My HP-91 desktop calc came with an 82031A adapter,
some of my other machines came with the 82066B adapter.
They both have 8 volts output at 3VA alternating current,
so no difference from the electrical side.
However, the 82031A plug for the calc has a somewhat different housing, but both adapters fit and work with the HP-91. The 82031A won't fit into an HP 82161A, for example,
because the plug housing fits exactly to the HP-9x machines.
Regards,
Raymond
