we have core  from  the famous Dartmouth system!  
my friend Dave   who worked in GE memory ( then later  Honeywell)  had to 
go back to Dartmouth one  time to  work on  it...   I should have him sign 
this  core plane   also  have some  docs  for  Dartmouth too.... oddly enough  
  I got the artifacts  form a Dartmouth   related  instructor....
 
 
I  had a datanet  760 one  time  but  when in the  computer biz  sold  
it.....    Wish I  had a  datanet  30!
 
 
any  GE  hardware, docs, photos , newsletters   anything  from  that  era 
we seek to preserve here in  AZ   we were the home of  GE  computer.   My  
biz  was   on the other side of  desert cove  from what  was  the Peoria  
location Jim might remember.....

I always  liked the Honeywell 200, though I never used one.

It was featured in  Industrial Design magazine as an example of excellent
design.  In a  computer center you are always short of counter top space,
work  surfaces.  So Honeywell designed the 200 to be only about 42  inches
tall and made the top of the cabinets a Formica counter top.   As I recall
it was also on legs so you could sweep under it.

Then it  was marketed as a serious challenger to IBMs best-selling  1401
computer.  I believe it forced IBM to announce their System/360  before
they were really ready to.

The Honeywell 516 and its  successors resulted from Honeywell's acquisition
of minicomputer maker  Computer Control Co.

To bring the topic back to green keying, the 1960s  were the era of time
shared computing, often using Teletype Model 33  machines as terminals
for the users.  G.E. had early success in this  field with a system 
developed at Dartmouth, running on a pair of G.E.  machines coupled
through a dual-ported disk drive.  One was the 265,  which did the
actual computation, and the other was the Datanet-30 which  did the
terminal multiplexing and program editing.  The Datanet-30 was  possibly
the best of several computers specialized for communication  handling
and starting to put an end to the use of paper tape for storage  in
switching centers.  There were also the Collins C-8400 system,  which
sold well to the airlines, always a Collins strong point.  And  the IBM
7740 and there was a machine marketed by ITT but manufactured by  DEC;
and then Univac had a Real Time computer as well.

When the  Datanet-30 got long in the tooth G.E. developed a larger
more expensive  communication machine, the Datanet 355.  Apparently
this was not what  the market demanded.  Dartmouth upgraded their G.E.
computers to the  600 line, but used Honeywell 316 minicomputers for
the terminal handling  rather than the expensive Datanet 355.

The Datanet-30 was manufactured  in Phoenix, along with G.E.s other
business type computers.  Process  control computers were also manufactured
in Phoenix, but by a different  organization in the company.  Near the
end of its product life G.E.  top management decided the Datanet-30 was
a communication product rather  than a computer, and moved its manufacture
and support clear across the  continent to Virginia.  About the same time
the organization there  produced the Datanet-300 teleprinter terminal,
and later the Datanet-1200  terminal, operating at speeds of 300 wpm and
1200 wpm  respectively.
