Doug, I hope you don't mean you need to replace the
chips with broken pins.
This happened to a ROM in my oldest PET when I was trying to reseat it (poor
contacts in sockets - I eventually replaced them with decent sockets). I
stuck
a thin piece of metal - a staple, as I recall - into
the socket where the pin
was supposed to go, and soldered it to the stub of the pin. Worked a treat!
I can understand doing this for a ROM but it's much easier for
me to just go out and buy new-old-stock chips. Here in the Bay area
a few of the electronic surplus stores also have well organized
selections of chips. I stopped this morning at one that's close
to work, Halted Specialities (HSC). The woman behind the counter
had never heard of a 8T-anything and continued to write "AT26"
until I wrote it out for her. But in less than a minute she
returned with a plastic drawer with about 200 in it. I had the
choice between "black" or "white and gold". Sixty eight cents
each and they are all Synertec parts with 1975 date codes.
A few of these places also have large collections of old data
books that are not for sale, but for customer reference.
