But why would someone find that particular part of a keypunch so
desirable? I have many small parts of a verifier I broke up for spares
for my keypunch. At silly prices someone could make a career buying
keypunches and breaking them up for selling on eBay.

*BUT* is that's what's really inside the plastic package?
I would really like to talk to someone who bought one, and
actually fired it up.
Not all of the fake electronic stuff comes from China :^P

Hi Tim,
Good Eye,
I had to look inside but I found a sticker for a Ball Brothers Model TV-50 :-)
The main logic card is in fact a generic Digital VT-100 logic board. Although
I would guess the proms are different.
Unfortunately the CRT neck is broke :-(
Was not packed very well at all by the shipper
I guess I can search around for a CRT somewheres unless anyone has a idea. ??
So I guess between this and that SB-11 (And a TU-58 I don't have) we have the
makings of something interesting for sure. This system did at one time reside
in the custody of a Harvard professor according to whom I got it from. Wish I
knew a little more about what it was used for back in the day.

Ahh well no Line time clock is a gotcha. :-) Would have been a little easier
to Divine its true use if the complement of cards were still in it.
Well then what use would this be to a hobbyist other than the obvious hollow
it out and stick a PC MB in it and create some Sim pdp11 thing ??

Hi,
now I got some "models" a guy is offering me but I'm not sure about their
interface:
IBM 1615600 MOD 1 10SR-1
IBM 62 PC
Magnetic Peripherals 47073251
Seagate Sabre 368 (92651505)
Seagate ST43200K
The Seagate Sabre seems to be SMD (I'm looking for SA1000 and a friend of
mine is looking for SMD disks)
Anyone else knows the interface of the above listed disk drives?

Go too far down that road and you just have a KL10 cabinet with a PC-clone
emulator inside. At which point you may as well have kept the KL10 original
and just had a PC-clone running an emulator too.
Seeing as how the major operators of KL10's in the 80's were already
retrofitting switchers in, I don't think that putting switchers in today
would be the worst thing to do. But I bet the KL10's owner went out
of his way to find one as original as possible, possibly passing over ones
that had been retrofitted 15 or 20 years ago.
One of the most enlightened attitudes is that since all 10's after the KI
were already emulating (via microcode) a PDP-10, why not just do the
emulation on a little PC-clone and call the operating system and emulator
package "microcode"?
Tim.
I asked this before, however, I am repeating my request since
I don't seem to have received any responses.
I would like to purchase about 8 TU-58 tapes.
Sincerely yours,
