Re: Richard Wilder, hp 9100 Calculator

hi,

I am trying to locate a Richard Wilder, who repaired an hp 9100 Calculator years ago. Richard's adventures on this repair are logged in some of the Old Forum Archives, ... but the hp 9100 photo's and details have been deleted from those links.

If Richard is still extant, I would appreciate a contact email or PM, in hopes of recollections, notes or discussions for troubleshooting my hp 9100.

Particularly, a list of the transistors, etc. used to replace the failed HP transistors in the 9100, or other hints.

thank you,
rick
