I thought I would start a thread for those of us that invest (waste) some money in interesting vintage components to see if there is a C4004 or other surprise chip inside.
The only purpose of the thread is to show what we actually find inside the metal boxes that we hope will hold a surprise.
Please feel free to post your finds here.
Here a some recent items I have opened up....and some I wish I hadn't.
I bought this 1991 APOLLO II Morrow Aviation GPS cheaply on EBAY, opened it up and found a NEC V25 CPU plus a socketed AMD N80C188-12. _________________ My collection list (growing) http://johnorun.x86-guide.com/en/collection.html |

This week I found this mid-1970's NOS EAGLE SIGNAL TRAFFIC CONTROL CONFLICT MONITOR LT 200 and spent $25 for it on Ebay.
C4004 chips were used in early traffic light controllers and this looked like the right type of box to take a chance on and the big gold-pin connector in the front told me a board must be inside.
Turns out the chips were from the 1970's...but no jackpot here
I may have to salvage the Gold connector pins to make some of my money back. (Anyone want some nice NOS Potter & Brumfield relays??) _________________ My collection list (growing) http://johnorun.x86-guide.com/en/collection.html |

Hey John, that's a nice idea which can save some money. ... and increase bids on some other boxes, lol.
I'll take a peak on my stuff, didn't buy boxes recently but will share what I know.
As a first hint - but already documented here - the Kienzle Taxameter 1140 works with P4004, as I heared from an old Kienzle engineer they never used C or D packages.
In early ones you might find Siemens clones, at least from a 4002-1 memory. |
