2250 had a number of different models ... 2250-1 was direct 360 channel attach while 2250-4 was 2250/1130 combo ... (but they cost approx. the same). we had 2250-1 at the univ in the 60s ... and i used the CMS 2250 graphics fortran library from lincoln labs ... to hack 2250 support into the cms editor. the science center had 2250-4 (2250/1130 combo), which somebody ported a copy of spacewars from PDP1. http://en.wikipedia.org/wiki/Spacewar! misc. past posts mentioning science center http://www.garlic.com/~lynn/subtopic.html#545tech then summer of 1969 ... i got brought in to boeing hdqtrs to help with the fledging boeing computer services (bringing all dataprocessing into its own business unit). hdqtrs had 360/30 mainly used for payroll and the machine room was built out to add a 1mbyte 360/67 to run cp67/cms. This was tiny compared to the renton datacenter which had dozens of 360/65 and some claim to have $300M or so in 360 equipment ... which was being replicated at the 747 plant up in everett. For a long time, I thot Renton was the largest mainframe machine room ... but later i would sponsor Boyd's briefings at IBM ... and in recent bio ... it mentioned Boyd was in charge of spook base (about the time I was at Boeing) ... which was a $2.5B "windfall" for IBM (possibly $17+B inflation adjusted in today's dollars?). this has description of spook base ... gone 404, but lives on at the wayback machine http://web.archive.org/web/20030212092342/http://home.att.net/~c.jeppeson/igloo_white.html above has picture claimed to be 2250s ... but obvious is something else. Later replacements for 2250 i believe were repackaged/relogo'ed graphics display from Sanders Associates (in NH) http://www.pong-story.com/sanders.htm http://books.google.com/books?id=XK4v1gh0JroC&pg=PA31&lpg=PA31&dq=sanders+associates+graphics+display&source=bl&ots=62_kZWXpki&sig=zKyb8WrQnJUzEQFgVMcJBZvq-XQ&hl=en&ei=QVu9ToTQPKWsiQL63I2mAw&sa=X&oi=book_result&ct=result&resnum=5&ved=0CFgQ6AEwBA ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
