I could kick myself. I tossed out thousands of chips.

Thanks for the offer CPUShack. I'll get there.
I just found one small box with everything from resistors, trans and chips in it. Looks like stuff swept off my bench.

Most of the chips that were in original shipping tubes are gone. I found one box of misc but they look newer and mostly memory and some logic.

Hey Neon, speaking of things I forgot. I found some old circuit boards from initial research designs dating to about late 70's early 80's. It was a helicopter ultrasonic based warning and blade de-icing system. We called it the 'Moose' because of how the array mounted on top of the rotor, looked like a set of Moose antlers. This system or rather it's modern equivalents you can see today on military and rescue etc. Heli's used in cold climates. Heli's are very different from planes and the icing issues because of the lift and rotation airflow is one. Only on top centre of the rotors is the air quiet enough to get good data. Kinda proud to have been part of that development history and to see the products produced from that research saving lives. ahh Memory lane.

I found
ICL8038CC Precision Waveform Generator/Voltage Controlled Oscillator
Intersil ICM7217AIPI 4 digit presettable up/down counter and LED driver (100ma). Wouldn't take much extra current/voltage drive, to marry it to nixie tubes JAC

JAC. I still haven't found any Nix yet. I thought my old Heath/Schlumberger (say that fast) Freq. counter may have had nixie's but it is very early 7 seg led's where you can see the discrete points of light from the diodes to make up each seg line instead of just a solid line. Kinda cute. and the counter still works. I went through one box of tubes, sorry no luck.

If anyone is into ultrasonics I have various parts including some custom hand built transducers tuned for various frequencies. I have various computer peripheral chips as well but not yet sorted to see what is there. Some form the old IBM XT and 386/486 days. As for old CPU's of that vintage, a few but most got tossed.

This is going to be a long project well into winter I suspect. So I'll leave off for now and get more organized. I'll go look at the lists some of you people have posted here and see what I find and learn more about what goes on here. It will be a while though.
I'll see about making those pic clearer later today.

boards are of interest as well, so show the moose please:-)

[Terry]

Well wepwawet they don't look like very much other than a pcb. Perhaps I'll take one of an early wire wrapped boards from the same project, to show the younger crowd how we used to prototype in the old days.

But here is one that may interest some of you. Here is that DEC 16k core memory board from an old PDP 8 or early -11, if memory serves. Those blank areas are supposed to be there. It's not damage. If you zoom in you can see the wires crossing and each one are finer than a human hair. DEC was the world leader in this kind of tech back then. Right up there with IBM. This board is one of the better ones I've seen a picture of recently. 16k was pretty impressive and I bet it still works.

I think I'm getting better at scaling. The picture should zoom better as well. That is genuine 70's dust on there as well As for size. It is sitting on my scanner. It was to big to scan. So it is several inches bigger than a legal size piece of paper.

[JAC]

Ah, that core memory is very nice. I am hoping to pick up a board like that one day.

[kosmokrator]

i think i the biggest core memory board i have ever seen....
interesting stuff!!!

[Terry]

It is actually colorful and may I say quite pretty in it's own right, when you look at it close up. It's amazing in how it was constructed and it definitely is one of those rare technical items that is worth framing, as a work of art.
