HM1802A ?

[oldgoldman]

Can't seem to identify. Too afraid to remove from socket in fear of busting pins.

On a CPU board .. possibly EATON Mil Spec ?

Its a microprocessor, likely made/sourced by Raytheon. WEBFLIS is your friend!

5962-00-264-2000 is the NSN

Funny, it's got gold showing, but the DOD Precious Metal Indicator code shows no precious metals, meaning less than 10 grains of gold (<0.0228571429 ounces of gold).

Cheers,

Okay .. I couldn't find this one anywhere... even on WebFlis.

After years of looking at similar part numbers that was my first guess also on the 40-pin chip, a microprocessor possibly equivalent to a 6502. Although I'd have guessed maybe manufactured by RCA since that 1802 number kinda rang a bell (RCA 1802 COSMAC). This probably was not made by RCA though since they wouldn't likely miss the chance to stick their name on it.

The second photo with the smaller 24-pin chip is also a microprocessor, a MOS Technology MCS6503. Much of the 65xx family chips are virtually the same as their equivalent 68xx family chips. I don't recall who made what first but some of the same designers worked on both families for different companies, which I believe accounts for the similarities. They were very popular processors and multiple companies manufactured and sold equivalent parts such as MOS Technology, Synertec, Rockwell, Motorola. 6502 chips powered the Apple ][ computers and the Commodore Pets also.

Don't know if it helps any but it looks like you are dealing with old telecom equipment. I have several of those bigger chips with the gold labels that look like heatsinks and bunches of the little ones. The smaller ones with the plastic are made by texas instruments quite often as well.

Very handy, thank you!

the HM1802A is made by Hughes ( HM, HE, HCMP, HC )

These are HC1802

I had a microcomputer with an 1802 cpu. It's not the same family as the 6502. The code is completely different I used to write code for both. I suspect it's worth more as a collector's item than for the Gold.

I have repeatily read and believe that many components are worth more to collectors than the refining value. However I have yet to find a site that specializes in vintage electronic components or equipment. Watch me find something as soon as I post this but If I don't..... Someone please point me in the right direction.

Thanks,

I am always seing this type of vintage stuff on Ebay!

 

[philddreamer]

I did a search for one, Sun mach64 PCI part # 113-37701-111, (C) 1998
that I have, this outfit is asking $180.50 !?
I need to check these chips a bit closer...

P.S.
I think it might be for the whole card...

The cpu-world forum is where those folk hang out.

So I don't know if anyone else saw it, but a MCS 6502 Gold Top sold for $2,200 on eBay.

Assuming .. the MCS 6503 isn't a $2,200 Chip also ?!??

Any thoughts from anyone ?

That one .. what's the deal ?

I don't know. Collectors are funny. Just list the one you have to see if that buyer wants to add yours to his collection as well. You know, for $2200. Unless you feel like having a sale.
