I remember GCC! I've used that 75. (NOT the place of my earlier story, despite the similarity.) I was so impressed because I could put a 500-card assembly in the reader and stroll over to the printer and by the time I got to the printer the assembly was done. Blew me away!
Talk about lights! That 75 had AFAIR 64-bit words displayed bit-by-bit across the front. A meg of main plus a meg of aux? Does that sound right? It was a beast!

I.T.) back in those days. I worked weekends as an Operator at Greyhound Computer Corporation in S.F. with a 360/30, 360/50, and 360/75 on the floor. A mezzanine ran across the upper floor used as client work areas. On a Sunday night, one of the senior system programmers, Tom, and two of his friends walked in and said hello. Shortly after, all of the overhead lights started to shut off, and as I was trying to figure out what was going on, I spotted Tom and his friends enjoying a System/360 light show from the mezzanine. After about fifteen minutes, the overhead lights came back on, and Tom had cleared out. I'm certain that illegal substances were involved, but no harm done and another weird expereience logged in this interesting and long lasting occupation. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
