I agree that many PDP-8s have the problem that peripherals are unobtainium.

I haven't had too much trouble amassing paper tapes and paper tape equipment
from eBay.  (I hope to make a contribution to bitsavers "real soon".)

I have also done some boards to interface some older PDP-8s to "modern"
(RS-232) peripherals, which allows at least some of the experience to be
preserved.  (Though loading paper tape images at high speeds over RS-232 is
qualitatively different than noisy 110 baud TTYs.)

I am also doing an RX01/RX02 interface board (debugging that is the other
project on the "real soon", pile).  That would allow you to run OS/8 with
peripherals that are still somewhat available (but "vintage", in that they
were actually used with some of the later PDP-8s).

There are also a few other projects I have been working on to replace all
those missing peripherals.

That's why a community is so useful.  (Not everyone should need every
skill.)

Now, if I could get these plastic switch handles to come out the right color
and get the little hinge tabs the right shape (and get my taxes done, etc.
etc.)...
