except a 186 and 8085, both of which never saw any real use as microprocessors

Hmm; didn't the RM Nimbus run on an 80186?  Reckon there were a fair few of those kicking around in the UK educational market in the late 80s through to the early 00s...

Gigantic HD68HC000 chips like that I've seen in arcade cabinets. Also the Mostek 68k chips. Just interesting since we mostly consider them a Moto part.

In the products I worked on, both 8085 and 186, we always demux'd the address data bus so we could use off the shelf memory.  In MHO, the 186 was the smartest processor Intel ever designed.  Those 3 timers and memory chip select in the peripheral control block made this a supper easy to use processor for imbedded design.  The 80386EX was a real nice upgrade to the 186, yes again for embedded applications.  There they added the first memory management unit, and SMM system management mode (supervisory mode in the 68000), which I always wanted to see used but we could never got the OS operational before the application ran out of gas with the processor.
I just retired, so I guess this is for adults only.

Did I see some Z80's in there? 

[codeboy2k]

I recently tossed a whole bunch of vintage chips in the trash, I couldn't sell anything.. I had a few z80's, 8080s, 8085s, 2716s, 2732s, 2102s, 2114s, lots of 74LS series TTL chips, etc...I put them on eBay. eBay started charging $1.00 for every item for every month it's listed, after 3 months and several free dollars to eBay I took them down and threw them out.

I still have some of them, but nothing like I used to have.

I think I still have an Altair 8800, an old KSR-33 teletype, and a bunch of S-100 boards back at my childhood home.  I used to have Microsoft 4K Basic on punched paper tape back then, around 1976.  I wish I can find that one.  Bill wrote it himself, I was only 12, and I was disassembling his 8080 code to figure out how it worked, and then I added a whole bunch of my own BASIC keywords to his code, since I had 32K of RAM

[SeanB]

Still have a box of pulls, assorted chips, eproms and such. A lot of 8255's as well.

I also have some old hardware, most of this is from some navy navigation/computer systems...

so.. rather than keep paying to try to sell them you immediately just threw them away instead of say giving them to someone on here provided they pay shipping?

Unless you were planning to pick them up locally, you are asking codeboy to volunteer time to get the parts to you. This can especially be a hassle for international shipping. Note that Dave stopped shipping the uCurrent internationally, even though he did get paid.

I hope you are talking sh it because if you really threw ICs away - especially 74LS ones (which I always need) then I have to say that would definitely put you in the running for a "xxxx of the year" award

If this qualifies for your 'xxxx of the year' award, then you either have some seriously screwed up priorities or live a very sheltered life.

[SeanB]

Saw one old bombing computer this weekend, if I had the cash I would have bought it......... Might go back next week and see if it is still there and haggle a lot.

I want one, I used to work on the later versions.

That's a pity, if you posted them on CPU-world forums, the trade section, I bet you'd have many takers in just few hours. Most people just collect them but some like me get them to eventually build some retro project. I didn't use PC in the pre Pentium days so it's exciting to get working some of the older stuff, I just treat everything as microcontroller system

Speaking of disassembling 8080 code, I'm trying to reverse engineer firmware of one Metra multimeter. It uses Czech 8080 clone (for main computer board, there is slave 8748 in the isolated analog section but I didn't read back that one yet) and I don't have experience with this architecture. Turns out 8 KB of machine code is a lot I think just labeling the subroutines would be a great progress. Experienced 8080 users would probably recognize some parts right away or at least give me some hints. So if you or anyone else can help me a bit, I can send you the schematics, manual (only in Czech), tell you the memory map, 7-segment character encoding and such what I found so far. I have to make some project page for this, didn't start one yet, now I have just the git repo on bitbucket: https://bitbucket.org/jnd/m1t-380-firmware/overview, it has the current disassembly listing.

it really isn't hassle - you're comparing Dave shipping out loads of something repeatedly to someone potentially having to ship one thing once that he would of been shipping if he had sold it on eBay anyway.. I'm not saying he should send them me specifically but there are loads of people like me who would have need for them and would have snapped them up outside of eBay, not everyone can sit on eBay for hours and hours checking to see if someone has put something cool on. it just pisses me off when people just throw good stuff away cause they are too lazy to give them away.
in the past when I haven't needed something I've offered it for free and was perfectly happy to post it to them if they paid shipping costs.

yes, as an agoraphobic - I have a very sheltered life - electronics is almost everything to me except for writing music. when you live inside of 4 walls you have no idea how little
priorities affect you - in fact it's pretty much - shower, breakfast,wait for the post, curse the postman for not arriving quick enough, speak to the postman for 5 minutes about the band he's in,lunch,soldering stuff, play guitar,internet, dinner more soldering, watch Ray Mears for the 3 millionth time that month, go to bed - repeat.
also you don't have to take banter insults on a forum quite so seriously.

I remember buying one of those and being blown away by how much faster it was than the IBM PC with its 8088 processor.

Too bad they weren't 100% PC compatible or they might have been a lot more popular.

Thank you for that link! Another fascinating and useful site I'd never heard of.

I too get a bit steamed about people who destroy/bin tech-relics because they are too unimaginative/unmotivated to find some easy way to pass them on to someone who'd appreciate them.
From codeboy2k's post it sounds like he ebay-listed his chip collection as many items, trying to maximize price. Then got annoyed when that didn't work, and almost vindictively binned them all. Can it really have never occurred to him to list the entire collection for $1 (starting price) plus pack and post?

[codeboy2k]

Wow.. I didn't realize I'd created such a firestorm here because I couldn't sell somethings and had to get on with my life.

As for those items, yes, I did have them, and I did list them individually, and in bulks of 5.  Not to try to maximize profits, but to try to actually make something usefully available for someone trying to find specific parts.  I didn't think a grab bag or box of unknowns would be meaningful to anyone.

I was in no hurry to sell them, and I would have happily listed them forever, until sold, but eBay wanted to charge me $1.00 for each listing, for every 30 days.   That made no sense to me, so I took them down and I needed to move on.  I just tossed what I thought must have had little value anymore.

Every single chip I tossed can be replicated on a single CPLD or FPGA all at the same time, in one package, wired anyway I want to without even lifting a finger to wire it.. discrete 7400 series and cmos 4000 series don't seem useful anymore, except to anyone repairing old stuff I guess. So perhaps thats the value I attached to them.  I've been working with 7400 and CMOS 4000 series chips since I was 12, and these days I have made the leap to micro's for control, CPLDs for glue, FPGAs for high-speed processing.

That picture in the OP's post just reminded me of what I used to have, so I posted a comment. Note that I have been carrying those items for many 10's of years already, across 3 countries and several homes.  I'm not getting any younger, and I needed to clean up my household.

I still have more old items here. When I find something interesting, I'll be sure to post in the buy/sell section here to see if anyone is interested.

Cheers!

I'll check that website next time.  Unfortunately I don't think I have any more CPU's.
I did manage to sell an 8080 and 2 8085s on eBay for about $9.00 each.

In that website, there was an D8088 ES listed and sold for $190.00 ... why on earth would anyone pay that price?? 

[amyk]

And here's an early 6502 on eBay that sold for $500+ : http://www.ebay.com/itm/111004383991

ES and other rare chips are much more valued.

I'm sure if you advertise free chips with local pickup on these forums, and don't live in the middle of nowhere, you'll get a lot of takers.

P.S. the Visual6502 project wouldn't mind getting some donations either, and not only MCUs too.

[codeboy2k]

I spent a lot of my early life on 6502 too, although I don't have any more CPU's or peripherals or even the complete hardware systems which I used to have ( I did sell those complete systems , not throw them away! )

Although I wasn't the original author on any of this, I did have a chance one time to work on the firmware in the D9060 and D9090 hard disk drives.  That was a fun point of my early career.  the D9000 series was a 5MB and 10MB 8" winchester drive, with a complete 6502 computer inside running a DOS, which shared a lot of its code with the DOS inside the PETs, the CBM series, the 4040, 8050 and 8250 dual floppies, the C64, the VIC20, etc.  They all ran basically the same DOS code, and bit banging the IEEE-488 over the parallel peripheral chips.

I think I might have some code listings around ... I'll have to look and see when I have a chance..

[jaqie]

not quite as old as the rest of the discussion here, but I recently built a 386 hotrod from (almost) era parts, am quite proud of it.  I was working on a 486/66 until the beginning of this month, too.

Here are a few pics of the 386. I hate the bodged case, but it's all I have and I think I made it work and look great considering.  Note since this pic set I have changed the SCSI card, changed the zip drive to a scsi one, changed the panasonic interface 2x cdrom drive to a scsi 2x cd drive, gotten a serial/lpt card, and replaced the ide card with it since I no longer need ide in the system.

My gosh! I think I might have some of those!  (Maybe, but too lazy to dig for them.)
