I could use a few new ones.

I scored a load of about 100 of them on ebay a couple years ago. I
have been giving them to whoever needs them for any use I consider
legitimate like that.
IE, they aren't replaceable, so, I won't just consume them for
something dumb, but for repairs of old machines and maybe a small
number of programming jigs or something. I gave some to a museum to
have in inventory for repairs. If I die and still have 75 of them and
someone else keeps them and dies with still having 60 of them, and so
they are available for repairs for the longest time possible, and 50
years from now there is still a box of 50 of them... that is my ideal
goal.
Hi Brian, I have been looking for one of these to make a basic rom for
my PX-8. Would you be prepared to send one to Australia?
If so lease let me know how much you want including shipping.
Thanks,

I said before maybe you meant the carrier not the socket, but I guess
you would want a socket too, so that you could re-write an eprom without
bending the chip legs again. Also for copying old original roms. No problem.
But just for the record, here is another option. I made a version of
Teeprom that has a standard 27C256 pinout instead of the special Model
100/102/200 pinout.

It's more complicated than just putting a dip chip on a carrier, but the
point is it has a re-writable EEPROM on it instead of a UV EPROM, and
you can write it with a generic SOIC-28 test clip instead of the special
Molex socket. The test clips are a bit expensive at $35, but the point
is they are at least a generic standard replaceable thing where anyone
can get one any time.
