Re: HP-41C non working Message #3 Posted by Raymond Del Tondo on 14 June 2005, 5:46 p.m., in response to message #2 by Artur - Brasil
Hi,
I've seen several malfunctional HP-41 CPU boards.
In most cases so far there were one or more defective memory chips,
in two or three cases a bad ROM chip.
Remarkable is that it always was ROM 1,
or in other words, the second ROM chip.
Too bad one of the boards with a bad ROM chip is a CX:-(
Best Regards
Raymond
