I had a brief exposure to Burroughs machines in the mid-1970s. I would say that the B6700 was definitely a mainframe, as well as the B6800 that followed it.
I've never worked with any Univac mainframes, nor am I familiar with the current line from Unisys. It has been said here that the current Unisys machines use x86 processors. I don't consider that to be relevant in discussing whether or not they are mainframes. IOW, whether or not anyone is doing it, it is possible to design a mainframe using commodity processors, x86 or otherwise. -- Tom Marchant On Tue, 1 Aug 2023 16:10:48 -0400, Rick Troth <[email protected]> wrote: >On balance, I encountered a Unisys machine, with the instruction set of >a much older system (which might have been a mainframe in its time) >which was definitely *not* a mainframe (because the contemporary box >just did not fit the class). >So Unisis machines not so much. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
