Does anyone know ... are Kevin Leonards 3380/3390 mods a complete
replacement for Jim Morrison's? Or are they supplementary?

Thanks!

Sorry it's taken so long to get back to you. Recent monsoon rains here resulted in water in my basement office, which has been drying out. Finally starting to get back to normal.

My version of the DASD mods was intended to be a complete replacement for the existing version. I've even coordinated what I was doing with Jim. There's a complete tape of version 1.02 of the mods here:

http://www.j76.org/vs2/das102-091011.zip http://www.j76.org/vs2/das102-091011.zip

and cover letters here:

http://www.j76.org/vs2/das102-091011.txt http://www.j76.org/vs2/das102-091011.txt

The problem with this install is that they only install on top of a system that has never had a prior version of the mods installed. Since so much of what gets changed is in DLIBs, most or all of the mods get accepted, so there's no convenient way to remove existing mods so the new ones can be installed. I'm going to have to come up with a superseding installation package.

The new mods fix a couple of problems with the old mods. One is new device types getting marked removable instead of nonremovable (the IBM SU64 macros have really confusing keywords, so the result in the original was the opposite of what was desired). Another is assembly errors if you try to put the master catalog on a new device type.

Another is a wait00A in NIP if you try to put the master catalog on a new device type. That's an IBM bug; I split the fix for it from the rest of the tape, and put it here:

http://www.j76.org/vs2/m096220.zip http://www.j76.org/vs2/m096220.zip

and cover letter here:

http://www.j76.org/vs2/m096220.txt http://www.j76.org/vs2/m096220.txt

The device error recovery support for new device types is incomplete. I did IFCDIP00 but that's all. I think Greg Price has everything else.

Still no support for page data sets on new device types. That's going to take someone who knows more about ASM than I do.

OK thanks!

Let me go back to a VS2 3.7 system and apply your mods and see what happens..

I use the Jay Moseley build instructions so I will see how the DLIB job
needs to be modified to take your mods as opposed to Jim's.
