Hi all,

I have a spare MOS 6502 that I am putting up for sale on eBay. It is datecode 5176 and has the earthstrap.

Listing here : http://www.ebay.com.au/itm/White-Ceramic-MOS-6502-CPU-MCS-6502-Apple-1-II-e-IIgs-/182019364143?ssPageName=STRK:MESE:IT

Given that it has had some repair to a couple of the pins, but does work and looks the part when in a board, do you think my starting price is fair?

Should I put a buy it now price on there and any idea what would be fair?

Thanks,
Dean

Dean,

Welcome to the board!

Very Cool.

If I might ask...where did you lay your hands on that zif socket?

I have never seen one like it.

Hi Steven,

I salvaged the ZIF socket from a PIC programming adapter I had lying around. The pins on the bottom werent really long enough to be able to use it directly into a mainboard socket, so I soldered some veroboard (stripboard) underneath, to which I soldered 2 x 20pin headers (offset 0.1" from the zif pins).

Then after all that I found that the pins on the header were a little thick and would stretch the IC socket a bit more than I would have liked, so I pushed a spare 40 pin IC socket onto it and used the legs of that to go into the mainboard socket.
Some pics that better explain:

I have done something very similar. ZIF sockets have bigger pins than normal so putting them in a dual swipe socket makes it safer when testing chips so you don't ruin your board.

Personally I use a Briel replica-1 to test 6502 (and 6820) just incase. I don't like risking something vintage like an apple II.

Cheers,
Corey

Here is a recent sale on ebay for reference: http://www.ebay.com/itm/MOS-Technology-6502-White-Ceramic-Apple-1-Kim-1-1976-/301853927333?hash=item4647e567a5%3Ag%3A7TYAAOSwuYVWoWtU&nma=true&si=yV7AF%252FIWy5BX%252FLVjpTIDZd4yxC0%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557

With the repaired pins you should expect a bit less.

I purchased one of the same style and vintage about a year ago in good condition except a bit of corrosion on the gold plated pins for $900 USD

Wow - those examples make mine look like a bargain then, though in better condition.

It's a pity about the pin design they used on these chips - there is very little material at the bend which does seem to make them much more fragile than regular chips.

Be interesting to see what I get for it assuming it sells - I'm hoping to raise funds to help me complete my mimeo.
