Hi
A guy popped up on the vintage computer forums advertising his ebay
sales of surplus items. Some nice DEC and Sun gear:

The PDT-11 caught my eye, what is that thing? Some kind of micro-11
Cheers,
Pontus.
In one word Yes. PDT-11 is one of three possible configurations
The most popular is the PDT-11/150 with is a box with 2 8" floppies
(rx01 equivilent) that can run RT11 (cpu is LSI-11 + up to 28KW
of ram and up to 6 serial ports).
Next most common is PDT11/130 which is a Vt100 with base PDT11 CPU
but instead of Floppies it has a parallel interface TU-58 dectape
mounted. Each tapes are 256kb so it can store the same as RX01
Floppy and it can run RT11, but tape IO is SLOW.
Least common was the PDT11/110 with is the Vt100 with bast PDT11
cpu but NO local storage device. The expectation with this is
to remotely load it with MOP protocal from a host.
