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.
