HI

For those who just *have* to read up on this beast:

http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1949-10.pdf <http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1949-10.pdf>

Has all of the details as of it’s introduction in 1949. When new it sold for $600. 
That would not quite have bought you a new car back then, but it was still a lot of money. 

Bob
