All right, I recall working w/ the "real" 3215 on a 370/145 (I spent some time as an "operator", so I know enough of my way around the 360 and 370 era tape drives) though I recall dealing w/ a 1052.
One operator I worked with had the S/360 Operator's Guide (with the red cover) which he wrote "Quotations of Ex-Chairman Watson" on the cover (smirks). Mind you, I spent a lot of time working DECsystem10s, TSS-8... using Teletypes (35, and, later, 33s and even a 37). -soup On Fri, Oct 20, 2017 at 9:30 AM, Alan Altmark <[email protected]> wrote: > On Friday, 10/20/2017 at 12:38 GMT, Dimitri John Ledkov <[email protected]> > wrote: > I have proposed upstream systemd to not use color by default on z/VM, > > as it seems that the most recent HMC does strips escape codes > > correctly in the operating systems messages window.
