I am speaking from an "actual" collector value point of view. I use the
drives too.. No one wants them, DEC made too many of them so they are not
rare, hence , they are worth no $$$$$. They are not even worth the shipping.
The PDP-11/45 in 1972 was shipped with RF,RS, PC05 type devices. People want
the *original* configurations.. not a bunch of *new* peripherals. Ie: SCSI
boards, etc.

Exactly, they are worth "use" value.. they just have no $$$ value - which is
what I am after.

Yikes. Again, collectors like the original stuff *when* it was available.
There are a lot of 3rd party devices that are worth $$$ (8 peripherals).

Exactly, so if you wanted one then it would cost you considerable $$$. Same

Unfortunatly, PDP-8As aren't worth much $$$ (maybe $100 - so not worth
restoring) so they would be stripped and the cards would be placed in an 8E.
BTW: I have an 8A I stripped for the interfaces if anyone wants it for the
cost of shipping. [that's box PDP-8/A-500, CPU and memory]
