Understood.? Having never seen VTP, I can't comment.? However, being an avid ICCF user, I can only hope VTP can be a reasonable substitute. Now my task is to find VTP 3.7!? Any idea where?

Hello Jim and Rene I still had the directory on my PC containing the DOS/VS system I was playing around with back in 2022 so I thought I would have a look and see if I could bring it up again and try

I just tried to run VTP 3.8 with supervisor $$A$SUPV and POWERV with no more success. :-( For sure, it is easier to install, and it runs with DOS/VS as a guest under VM/370 (despite the opposite

Mark, To be honest, I was fascinated by PS/44.? I only recently learned about it when I was preparing for a presentation, I’m going to be giving at the VM Workshop later this week.? Part of my

Greetings Professor, It is so nice to hear from you again. Jim, you are exactly where I was yesterday after spending an entire afternoon trying to make this VTP 3.8 work. I was assuming you were

Jim, you are exactly where I was yesterday after spending an entire afternoon trying to make this VTP 3.8 work. I don't know why it behaves like that. However I noticed that the system storage map

OK! What an interesting trip down memory lane. . . 1. I reassembled the POWER module changing 'ACCOUNT=NO' to 'ACCOUNT=YES' and called it POWERA. 2. I copied POWER SYSIN to POWERA SYSIN and changed

John, So, what is your interest?in PS/44?? Did you ever work with the model 44, back in the day? When I attended Clarkson College of Technology (now Clarkson U.) in Potsdam, NY from 1971 through

Thanks Joe for the Wikipedia link.? A lot of detail and additional links.? When I get a chance, I plan to copy to my system. Harold

According to the Functional Characteristics the 2315 drive had 200 cylinders + 3 spare. Each cylinder consisted of 16 sectors of 366 bytes each. It supported '0001011' + 1 byte for seek

I dont the 44 supported FBA... A unique feature of the Model 44 is its integrated single disk storage drive which uses the *IBM

The model 44 was a specialized box. The largest amount of memory was 256K. It didnt have some instructions. https://en.wikipedia.org/wiki/IBM_System/360_Model_44 Joe [email protected]>

By which I am assuming the format of the disk is unknown and possibly the contents. I have tools in SATK that can readily build a FBA disk image. But you do need to know what goes on it and how it is

Assembling it would not be a problem, DOS should be able to assemble it. However what we have is only the changes from PS/44 to make MPS/44. What is lacking it the tools to format the disk and load

Is the format of the disk known?? Is the content on the disk also known?? I have a lot of tools for building emulated disks.? So might help. I am assuming running the code would use an emulator of

There is source for MPS/44 which is a variant of PS/44. However it is incomplete. It is missing the utilities to create the disk and load it. If you do find it let me know. Rich

Has anyone found a copy of the installation tapes for this specialized operating system. PS/44 was designed for the s/360 Model 44, and only allowed Fortran to run. John Rankin
