Thank Ya thank Ya Thank Ya
Nothing is marked on the board and I didn't really look to see if they were marked on the package. I will check though! Thank you for the reply. I do know that all the boards say they are made in 1981. Would there be a difference in these compacitors in design vrs the mlcc?Topher_osAUrus said:myfalconry76 said:I'm really interested in the little colored resistors or compasaters or what ever they are and of course the black chips?

Which colored resistors?
I believe i read that the rainbow colored (not exactly rainbow..) are tantalum capacitors, but i cant really tell from the picture.
Im sure most have markings by them, I.E. r01, r02, c11,c12
R is resistor, c is capacitor. There are a bunch of different other markings as well for transistors, quartz clocks, pretty much everything.
Its hard to tell what would be "worth" processing to you, but, i know i would certainly save all of the DIP packages, and all of the rainbow caps.
Ill see if i can find the website I was reading about all of the markings.
Hope this helps

As I said, a bit of a lottery, however I hope this helps.
Have you ever seen platinum plated traces on a regular board? Where have you found palladium traces?anachronism said:Some of the tracings on the boards- the exposed ones with no solder mask may either be lead/tin/silver or in some rarer cases they actually contain Platinum. The Platinum bearing traces are a dull darker gray.
