Yup, all 90 are marked SY6502. Honeywell? Wonder if my Honeywell

still uses a 6502 core. :)
I've got 90. If you only want a few, I can forget about the 30 cents
each and
just go for shipping. I can also hook you up with CMOS 65C02s for about
$7 each, via Jameco, if I'm going to be shipping stuff to you anyway.
With Jameco, sometimes you get a WDC65C02 (14 Mhz), sometimes
Rockwell 65C02 (2 Mhz I think). So far nothing as old as 1984 though!
I recommend at least one CMOS version since some code is written for
the 65C02, as you're no doubt aware. Daryl Rictor's SBC2 board (I've
built up 5) is one example. (What a nice board, by the way!)
Nope, looks like it's been in some sort of dry warehouse all these
years. Aside from
some dust on the outside of the tubes and the date codes, I could be
fooled into thinking
these babies came right off the assembly line last week. :)
Oh, okay. I guess I could offer to test them if and only if they want
me to.
I plan to keep quite a few for myself, but 90 is so ridiculous that I'll
be happy
to help out homebuilders like Philip with onesey-twoseys basically at
shipping.
Maybe later I'll ask for a buck each or something.

Hehe, you're imitating the inimitable E-bay style perfectly. :)
I have some Synertek NMOS 6502s from various
weeks
in 1984, still in their (original?) Synertek static tubes.
(At least, "Synertek" is stamped on the tubes.)
Ooh! That'll be good to up the value on Ebay a few dollars... Let's see...
L@@K!!!!! R@RE!!! SYNERTeK Sy6502 ***IN MANUFACTURERS PAKAGING*** ***NR***
:-) :-) :-)
A few "boy are these stupid" questions:
1. Does anyone have any cool Synertek lore they'd like to
share with the group? All I know about them is they made
the SYM-1 and were a 6530 second-source. I guess it's safe
to conclude they were also a 6502 second-source. :)
I think I've got some e-mails from a guy who used to work for them. From
memory, Synertek were a Honeywell subsidiary who signed a license with MOS
Technology to second-source the 6502. MOS used the part numbers "MCS6502"
and "MPS6502", Synertek used "SY6502".
From what
I've read, there were three licensees for the 6502 -
MOS Technology - later
bought by Commodore to become Commodore
Semiconductor, logo changed to ugly Commodore chickenhead logo
Synertek (see above)
Rockwell - I've got a full set of d-sheets for their parts.
2. Is this a "Find" in any sense? (I
paid all of 30 cents
each for them.) My motivation is to have enough replacement
parts to keep all my 6502-based hardware humming for years
to come. Though in this case I have several lifetimes' worth.
:)
I would call it a find. How many have you got? Would you be interested in
selling me a few?
3. Is there any reason to fear that these chips
will "go
bad"
at any significant rate as they age? Is there any way I
could
store them (reasonably, I mean, no vaccum or outer-space
suggestions, please. :) to maximize their lifespan?
They should be fine. If they've been drenched, expect some pin corrosion.
Any corrosion on the pins can be removed with a bit of contact cleaner.
My plan is to come into work some evening and suit
up with
the full anti-static treatment at an EMI bench with my
little
SBC (retrofitted with a 40 pin ZIF socket to avoid bending
their machine-straight little legs), and test them all in
rapid-fire succession. Is there anything inherently dumb
about powering them up?
They'll lose their "L@@K R@RE UNUSED" status, reducing the value by a
few
cents a piece :-)
Later.
