Anyone have any experience with these old IBM chips ?

Very nice board, I had some similar in this thread...http://goldrefiningforum.com/phpBB3/viewtopic.php?f=34&t=9585 Do you have many? I do regret I did not save some of the nicer ones. They really are works of art.

I only have 2 of this exact board so far .. but multiple smaller boards with similar chips on them. wondering if these chips off the board have very high value.. thanks for your input..that lot that you had was simply spectacular.

Looks like a board out of an IBM 3745 Comm controller.
I don't recognize the ceramic chips on the board. Who is the
MFG and do they have a part number?

They may have a gold plate on the bottom but you would have
to desolder the chips to see.

the one chip says: 66X2017 01 TCI17G100AY 0025 JAPAN 9614EA

they came out of a cartridge with either 3020 4MB .. or .. SCTL on the handle .. can't remember

i think you may be right about something on the under side of the chip .. there are no pins in the middle as evidenced by a blank spot on the bottom of the board beneath the chip center

thx
