Uploaded short (< 2min) video on TK5 on YouTube. Simply because it’s been out over 2 months, and I see absolutely nothing about it, on YouTube.

JCL course
Just saw this JCL course on YouTube. JCL? Which JCL? There’s more than one. Undoubtedly they mean MVS (style). It’s almost 2 hrs. long, so might be worth a look.
OS/390
I tried to watch a Spanish OS/390 install video, I saw on YouTube. All the comments were in Spanish, so nothing helpful there. It seems OS/390 can be downloaded from archive.org. So I downloaded ISO 1 of 13. I had a funny feeling. And looked more into it, and it seems illegal to run without …
MVS & DOS/VS screenshot
Running under VM/370 CE at the same time. Full consoles. Notice the different style 3270 MVS console. You can see compile/link/go on both consoles. The screenshot would be better if I didn’t use model 5 (wide) terminals for DOS/VS. Model 5 really only makes sense for the TK4- screen. You know where you might want …

VM/370 multiple OS guests
Today’s PC VMs have nothing on IBM who started doing this in the late 1960s with CP/CMS. VM/370 was released in 1972. I ran TK4- (MVS 3.8J) and DOS/VS under one VM/370…running in Hercules. Would anyone do this in the real world? Perhaps a school. IDK. DOS/VS is the only OS I didn’t bring completely …
