Found a TC59 (PDP-9, PDP15)

[gnupublic]

Hey,
today I had a look at a nice controller. It is a TC59 for PDP9 oder PDP15 for connecting tape drives.







there is also core for the PDP15, I think more than 12 (16?) 4k ensembles (core with five G100).
Who is interested? Please contact me.

All the best,
Volker

Volker,

There are only a few PDP-9s and PDP-15s left. One of the PDP-9 owners who may be interested in your tape controller is on this board. I repaired a TC-59 for the PDP-9 at the Rhode Island Computer Museum.

Your TC59, and probably the memory, came from the PDP-15/50, S/N 562, at the Institut für Strömungsmechanik (ISTM) at the Karlsruher Institut für Technologie (KIT) in Karlsruhe, Germany.

The PDP-15/50 was equipped with KE15 EAE, FP15 Floating Point, and a KW15 Real Time Clock. It had two MM15-AA 4kW core memories, S/Ns 1469 & 1472, and two MK15-A 4kW expansion core memories, S/Ns 1010 & 1179, and a KP15 Dual memory Bus, S/N 755. The TC59, S/N 5122 was connected to a single TC10 magnetic tape drive, S/N 5204. It also had a TC15, S/N 250, connected to a single TU56 DECtape drive, S/N 6903, an RP15, S/N118, connected to two RP02 10 MW disk drives, S/Ns 606 & 3, a BA15, S/N 687, control for the PC15, S/N 5526, connected to a PC05 paper tape reader/punch, S/N7668, an LT35, S/N142430 connected to a 35 ASR Teletype, and a LP15-FB 300 LPM printer. The entire system shipped in June of 1972.

That's interesting! But how do you know that in this detail?
This controller was in the barn nearby Göttingen. So that's quite far away from Karlsruhe (for Germany). I did not find any parts from PDP15 there. Maybe only in from of FlipChips.

A summary of the 18-bit maintenance contract summary from 1972 is available. It contains all of the details of the machines and options, including serial numbers.
