Maybe so, but Amdahl started shipping the 470V/6 in 1975 with 4 MB of memory standard, and I'm pretty sure that the 370 model 168 also had 4 MB in that time frame. I'm pretty sure that either of those processors would outperform a 360/75 by a considerable margin. According to Wikipedia, the model 75 first shipped in 1965 -- Tom Marchant > >BobL > >-----Original Message----- >From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On >Behalf Of Seymour J Metz >Sent: Wednesday, January 16, 2019 1:41 PM >To: IBM-MAIN@LISTSERV.UA.EDU >Subject: Re: Where's the fire? | Computerworld Shark Tank [ EXTERNAL ] > >"It's the late 1970s, and this data center has a high-performance IBM 360/75 >mainframe that sports a massive 1 MB of core memory -- one of only four in the >world," > >I might believe late 1960s, but by the late 1970s the 360/75 was well and >truly obsolete and 1 MiB was nothing to brag about.
