The Retro-Computing Society of RI has acquired a complete pdp-10.  On
22-AUG-2001 we transported it from Sikorsky Aircraft in Stratford, CT to
our facility in Providence, RI.  Information about the system and images
taken during the move can be found on the RCS "works-in-progress"
website

http://starfish.rcsri.org/rcs/DECsystem/1090/  

It was used for helicopter simulation from 1985-1994.  It was part of a
hybrid computer facility that also included two AD-4 analog computers.

This DECsystem-1090 is configured with 1.5M word of memory.  The
following image shows the three cabinets that comprise the KL10
processor and the six 256KW core memory cabinets.  The tall cabinets
span about 23'.  A pdp-11/34 based remote station can be seen at the far
end of the row.  Behind the band printer there is a general purpose
parallel interface cabinet.  (note: the images are about 1/4 MB each)

The KL10 contains a pdp-11/40 front end processor.

There are three 178MB removable disk drives and one 508MB fixed disk
drive.  A disk pack can be seen on top of the fourth cabinet; it is 10'
to that point.

The four blue trimmed cabinets contain two more pdp-11/34 based
communications processors and related interfaces.  Next is a 9-track
tape drive.  The five cabinet are 11' wide.  The fixed disk drive can be
seen again in the forground.

The estimated total mass of the system is 13,000 pounds.
