Subject: Re: value of RK05
Fortunately, I am not, never have been, and never will be a collector...
Agreed.
I understand.
Already has.
Preservation comes in many packages. If I can use the peripherals from one
*new*, very common computer in an old one then I would prefer to increase
the value and use of the old computer. If the subscribers on this list tried
to preserve every computer they got then they would probably be using
COCO-2s for insulation in their homes ;-). My objective has always been to
preserve any computer built before 1973 - and I have saved well over 60 of
those since the beginning of the year from the dump, crushers, etc... Not
every computer can be preserved , ie: PDP-11/34. If I saw an 11/34 with an
RK11-D in it I would take the RK11 and any other *useful* interface and drop
it into some older unibus computer made before '73. I get quite a few 11/34s
in and *no* one wants them. By the end of this month I will have gone
through at least 25 34's and I am getting another 8 PDP-11/34 systems in
June - who wants the CPUs???
I guess it's different for folks who don't get a lot of old systems.

Again, IMHO, it depends. I remember spending considerable time/effort to
track down my RK07s. Yes, I seriously wanted them. Still do.
Agreed. You *wanted* RK07s for a specific use.
> The PDP-11/45 in 1972 was shipped with RF,RS,
PC05 type devices. People
want
Actually, my 11/45 is an early one (it has the older boards and power
cabling). I happen to know that the original configuration included an
RK11-C (which I have, the one it came with), one RK05 (I don't have the
_original_ one) and a number of DJ11 serial ports (I have some DJ11s, but
not currently on that machine). Paper tape was added early on, using 3rd
party cards and devices. There _may_ have been a DX11 in the
configuration as well.
> Yikes. Again, collectors like the original stuff *when* it was
available.
There are a
lot of 3rd party devices that are worth $$$ (8 peripherals).
I've said it before and I'll say it again -- I am not a collector!
> Exactly, so if you wanted one then it would cost
you considerable $$$.
Same
thing as
collecting/restoring old cars, boats, radios, ???
Well, I used to be interested in old radios, but when the 'collectors'
moved in, it all went out of my price range. So I've still got the few
sets I managed to get before that happened, I've still got the valve
testers, spares, etc. But I'm not likely to get any more.
Looks like computer collecting may go the same way.

Err, of _course_ they're worth restoring. They're a 12 bit DEC computer
for one thing. And they're interesting to work on.
12 bit computers were obsolete at the end of the '60s. A 12 bit computer
built 6 years after they were *totally* useless is not my cup of tea... and
from the number of DEC engineers I have spoken to -
thye feel the same.
> 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]
And just how does stripping the interfaces out of a machine relate in any
way to 'preservation' (which, IIRC, is the main theme of this list).
