Speaking of which, I just took apart my Gateway computer.

I have a pentium II processor.

Its bulky, not square, and it looks like a N64 Catridge with a large heatsink attached.

Not sure if old enough.

Edit:
The TI Calculators have those old Z80 processors. http://ouden.org/z80.htm
And I have a lot of broken calculators from all those times I've dropped them.  :(

Catcher, yeah, PII's are kind of old (maybe 99). They're big. I have a box of them. Would not be good item to trade through mail. Thanks though.

jeckson, could you send me a list of what you have? Is shipping from Indonesia to US expensive?

Finaly got the beast out :-)
It is a 286 AMD so I guess it is not very interesting.
Here is a couple of pictures.

Interesting find. This is an AMD made 286 licensed by intel. It's probably later than 1984. Can you check to see if there are chips with markings like 8259A or 8237A in sockets? I bet this machine was a bit low end. The coprocessor slot is empty. Not exactly what I was looking for but if I can get the support chips like 8259A and 8237A, I may consider a trade.

any interest in a pair of Pentium pro 200Mhz chips? rooting around looking for an atx backplate I "rediscovered" them in my parts bin

Osgeld, yes I am interested in the trade. Will you PM me your address so I can send my board to you? Thansk.

well here are some pictures first

both have heatsink goop residue on them, and compaq part stickers on the underside, the one on the right has a slight scratch in the case and its pins did get a little bendy while being tumbled around in the bin, the one on the left has no bent pins or scratches so its just a matter of that old oem heatsink residue

Osgeld, they seem to be in better condition than some of my PP200MHz. I normally clean the processors with ethanol when I get them so no worry about the thermal paste. I'll get rid of it. I'm happy to trade with you.

First of all sorry for the late answer.

There was not any support chips like 8259A and 8237A.
If you are interessted in the 286 CPU I will be glad to send it to you free of charge, I just think it is nice somebody will collect and preserve something like this.
Please inform me, and if you would like the CPU, you can PM your address to me, and I will send the CPU as soon as posible.

Thank you Thomas. I've sent you a PM with my address.

I have some real odd balls... but I have no idea what they are worth.  Like  a beautiful AMI S6800 Ceramic.  Original Price (if you can believe it) of the 40-pin, ceramic, dual-in-line package 6800 MPU was like $350.00

Others examples of what I have:

Motorola: MC6809ES, MC146805E2P, MC68705U3S, MC68020RP25E
Intel: D8088, P8085A-2, P8088-1, C8751-8, D8751H, A80486DX-33, A80387DX-33
Philips: 80C31-3
Rockwell: R6502P3
NEC: D8748D
Zilog: Z80

My oldest CPU is an 8008.  125KHz Rules!

Catcher, sophos really doesn't like your avatar pic - it says it's a virus.

But the reason I'm posting is that I had a dream last night where I found half a dozen old processors in a box. :\

liuzengqiang

pwillard,

I'm willing to trade if you're interested. I'm interested in the AMi 6800. Does it have white/grey ceramic casing with gold stripes coming from the die to all pins?

I'm also interested in the rest but I think everything together is more than the value of even two PCBs.

Are you willing to trade with one fully assembled kit (including one hour of labor, LCD, RTC, 256KBit EEPROM, clock running on CR2030 battery) PLUS a bare PCB? What chips are you willing to trade with this offer? PM me.
