cjl mentioned the usefulness of various components for repairing
PDP-8 boards.  The place where I work uses 8641 chips in manufacturing
Unibus and Q-Bus boards.  We paid $7.50/chip for a bunch of National-
Semiconductor 8641 chips.  I think that some could be made available,
perhaps at less than cost.  These parts are new and in the tube.
The boards that these chips were purchased for are not being
manufactured in the quantity that they once were (what Unibus hardware
is? :-), so there are more chips available that anyone here will
probably want to buy.  (One of the designs uses >6 chips).

If anyone is interested, I can go to my boss and see how much the
chips could be aquired for.  To make it easy on accounting, I
would concentrate the orders into one buy from the company and
divy up the chips into individual orders.  I can also include
data sheets.  I am not, however, aware of which DEC chips these
are pin-compatible to (if any).

I just checked the stock room... the other parts in needless
abundance are COM 5025 sync serial chips, 4164 DRAMs and 74LS374
octal D flip-flops.

Let me know... If anyone wants to make an offer, please do so; it
will make my job easier.
