Hello, I have several of these boards pulled from what seems to be a vintage dumb terminal (large housing consisting of a keyboard and CRT screen with no apparent I/O ports). There are 8 boards in this unit of three different types. All three types have gold-plated finger connectors.

Board #1 is all IC chips with a few caps and resistors.
Board #2 is similar to #1, but has some IC chips with gold legs
Board #3 has a few gold-capped ICs and others with gold legs. Has the label "Memory" on the upper corner"

Thanks!

So, terminal boards #1 and 2 are going to be at least CGF boards, might go as high as High grade tele. Terminal board # 3 is going to be a gold cap chip board. For verification I would wait on lost or ccussins to post a reply to this. Good luck brother and nice boards!

Based on similar boards I posted that Chris and Lost graded and cross referencing Lost's post on CPU/IC chips.

#2 Should have no problem going High Telco with the ceramic ICs with gold legs and gold fingers.

#1 I'm leaning High Telco but an opinion from ccussins would probably be good. The ceramic ICs with gold legs on #2 helped me go high telco there, but this board doesn't have that so may not make it, not sure a board like this would make it in the clean GFC category or not so could be as low as low telco.

#3 Easily Gold Capped Chip board.

~~edited to correct for my swapping board order~~

Thanks for all the input. Just for clarification, Board #1 does not have any chips with gold legs. They're all just regular IC chips.

Not OP, but just wondering, what grade would these boards get if you were to trim the gold fingers?

Chris says that board 1 is High Grade Telecom.
