HP-25C needs chips to come back to life - Jean-Michel - 06-10-2010 Hello all,
my HP-25 I was given recently powers up and shows "0.00" on display, but unfortunately the keyboard remains non responsive. If anyone of you has some spare chips he could give/sell me, please contact me, I will give him the exact part numbers of the chips and the way to proceed. Before you tell me: I have already asked Randy (FixThatCalc). Unfortunately he does not have the parts.
Kind regards. Re: HP-25C needs chips to come back to life - Vieira, Luiz C. (Brazil) - 06-10-2010 Hi/ e-mail me. Chances are I may have one/some of these. linux underline lcv (at) yahoo (dot) com.br Cheers. Luiz (Brazil)

By the way... (was: HP-25C needs chips to come back to life) - Vieira, Luiz C. (Brazil) - 06-10-2010 Hi; did you read this post? That's the main reason I may have the chips you need. In fact, I have already tested two of the ACT units and they are not OK. I use an HP25 PCB with IC´s sockets so I can easily test any of them. Even the two IC's under the LED display are readily changeable. Cheers.
