recent scamp reference from last month
http://www.garlic.com/~lynn/2011h.html#53 Happy 100th Birthday, IBM!

5100, SCAMP: Special Computer, APL Machine Portable
http://en.wikipedia.org/wiki/IBM_5100

based on the PALM processor: Put All Logic in Microcode
http://en.wikipedia.org/wiki/IBM_PALM_processor

cambridge science center had taken apl\360, and stripped out most of the
monitor stuff (multitasking, swamping, etc) for cms\apl (under cp67,
also redo storage management for large demand paged virtual memory
environment; typical apl\360 had been 16kbyte to 32kbyte real-memory,
swapped workspaces). recent news item mentioning cp67

Before the PC: IBM invents virtualisation (Cambridge skunkworks)

misc. past posts mentioning science center
http://www.garlic.com/~lynn/subtopic.html#545tech

5100 was done at palo alto science center. About the same time, Palo
Alto also does apl\cms (for vm370) and apl microcode for 370/145.

one of the largest APL services was HONE (first cp67 then moved to
VM370) ... internal world-wide sales & marketing support:
http://www.garlic.com/~lynn/subtopic.html#hone

in the mid-70s, the US HONE datacenters were consolidated in building
across the back parking lot from Palo Alto Science center. other trivia,
looking at web satellite phote of the area ... a newer building was
built next to HONE datacenter (which has a different occupant now)
... that newer bldg is now occupied by FACEBOOK.
