Ciao Ward Dossche,

FB>> IBM 360/390/zSeries (MVS, VM, OS390, zOS ecc.) are mainframes. ;)

WD> A 360 and that family ... 'mainframes' ???

WD> You must be very young ... :-)

More than you? certainly! :P
I omitted CDC because them weren't so spread like IBM ones.
If you meant Univac or similar, I'm sorry but you can't put them in te mainframe category, them were simply computers. At that time them didn't have the characteriatics of a Mainframe.
A mainframe is a computer with a really high speed in the peripheral system, capable of run thousands of terminals and jobs with intensive I/O and before IBM 360 none had this capability, neither the 1400, maybe the 700/7000.

I worked on a VAX 11/780, but (unfortunally) I never had the opportunity to work on a mainframe. :(

Ciao.
Fabio. :)
