Hello, I have searched extensively for a copy of the IBM manual(s) for the UCSD P-System. (This was an alternative operating system to DOS and CP/M for the original 5150 PC). Does anyone have a copy, either electronic or physical that could be shared, sold, etc? Thanks! Michael

I once had a set of manual of the UCSD p-system for the Texas Instrument Professional PC. I have scanned them and then some guy in Germany has taken car of them. Here is a link to the scanned files: https://drive.google.com/open?id=1IRSeIJfLFO9GELcD9AbZ-CTDxKcY8juP Please note that one of the manuals is still individual TIFs and has not been concatenated into a PDF.

Not exactly what you sought for, but maybe almost as good?
 
Those manuals are absolutely amazing! Definitely will get me going while I continue the search for the IBM. Thank you so much. Michael
 
I'd expect the TI manuals to be similar, since they were competing against IBM and wanted similar level software (To the point where they even confusingly renamed their MS-DOS 1.25 OEM to "MS-DOS 1.1" for perceived parity with "PC-DOS 1.1" )

I've been meaning to ask if the UCSD P-system described here is a genuine dump of IBM media and if it is the first IBM release or a later update. As usual, they didn't include label scans.

The thing that I don't get, I have several application program disks that were authored with the UCSD P-System and they have really weird formatting with odd sector numbering, although it did not claim to be copy protection. I had expected genuine IBM UCSD to use a similar odd format, so I am a bit surprised to see an image in a simple image format. Of course, the blog does not say where they sourced this from.
 
I have discovered a few tricks working with various UCSD disk images. Some images have an extension ".IMD". I have found that these images can be converted to a binary format by using a program in Dave Dunfield's distribution of Imagedisk. ( http://www.classiccmp.org/dunfield/img/index.htm ) The program to convert is called IMDU, and it is used by selecting the /b option for binary output. This process was mentioned by the fellow at the z80 blog.

After the binary output file is created it can be converted by a process I have seen referred to as "Bursting". The Burst process extracts the individual files from the binary file. The program to do that process is BU. ( https://www.threedee.com/jcm/diskutil/index.html ) There is a discussion at the website of this program and the motivation, etc.

Once you have the individual files on the disks, it starts to make more sense what is there and what they do. I will try to post some images that show additional information. Can't do it right now. Michael
 
Thank You Al for posting those links! Extremely useful. If you are reading this and have any present/future interest in running UCSD P-System on an IBM 5150 I definitely suggest grabbing both items for your archives! Michael
 
Very nice. That looks like it has everything except the UCSD Pascal Compiler package. But unless I'm mistaken, the UCSD_IV_3_PASCAL.IMA on the z80 site is the UCSD Pascal Compiler disk.

I guess that also answers my question about the disk format. The application disks must be the oddball ones.
