Now that I've had some time to actually use this machine, I am LOVING that I don't have to worry about whether a program is for CP/M-86 or CP/M-80 before I load it onto the machine. If it's CP/M-86 it will just run and if it's CP/M-80 I just have to tag the file using 8BIT.BAT to make it execute correctly. The only thing I really do have to worry about is whether the software supports my terminal. I bought a Kimtron KT-7/PC off eBay and it seems to have Televideo 925 emulation and everything I've tried so far that's configurable does seem to support it.

Any way to bypass a password login in CompuPro Concurrent DOS?
- Thread starter jmetal88

With CompuPro CDOS 5 you can also run DOS applications with significant limitations: (a) only applications that work with PCDOS 2.1 or earlier will work and (b) the application must only do character-based input/output using standard DOS function calls. On the CompuPro CDOS master disks for the 10+ that you have, I believe they provided only one DOS application which is TIME.EXE.
You first need to make a DOS partition, which you are permitted to do on any partition except the boot partition (ie hard drive partitions B and higher). To do this, run the CompuPro utility "MAKEDOS X:" where X is the partition you want to turn into a DOS partition.
Once you have created a DOS partition, you can then run the MKDIR utility to create a DOS subdirectory.
While this is a great way to keep a lot of files organized, keep in mind that CP/M applications don't know about the concept of DOS directories. While you certainly can run a CP/M utility saved on a DOS partition and in a DOS subdirectory, should that CP/M utility require an input file you cannot use standard DOS terminology to provide the path to that input file if it resides in a different subdirectory than the application itself.

turned up what appears to be some cdos 4.1 backup 5" floppies that may have something interesting on them
and also a copy of FORTH-32 for the ns32k

CP/M 2.2 had users (0-15) set by one byte, but most CP/M software didn't make use of the different users and expected all files all to be all same user. Some of the CP/M replacement systems did allow some sharing of files in user 0 with whatever user level was set.

The point of CP/M "users" was to divide the disk (directory) up by "user number". It was not intended that software need to know about users. The User (operator, person running CP/M) would select which user number they wanted to "be in" at the moment, and software just looked for/created files without knowledge or consideration of the user number - the BDOS honored the user number selected by the person. CP/M 3 and MP/M (in the 8-bit world) will search user 0 for files if not found in the current user number, and many CP/M 2.2 vendors created CCPs to do the same (for commands only). PIP has options to allow you to use a different user number for source or destination, allowing convenient transfer of files between user numbers. But, application software was not expected to know about user numbers nor defeat the selected user number of the operator. FYI, CP/M 2.2 supported users 0-31, while MP/M and CP/M 3 trimmed that back to 0-15. You'll sometimes see odd thing in user numbers 16-31 if the disk was used on CP/M 3 or MP/M.
Password protection of files/disks was a separate thing, not tied to user numbers. CP/M 3 and MP/M honored password protection, although they implemented that differently and I'm not sure what would happen if you used (e.g.) an MP/M password-protected disk on CP/M 3. However, password protection was defeated if you used the disk on CP/M 2.2.
Again, it's not up to the software to make use of the user numbers, it is the operator that does that.

PLEASE look at the context of the REST of this thread.
It has NOTHING to do with 8-bit CP/M
CDOS != CP/M

Actually, CDOS is a superset of CP/M and does contain many of the filesystem concepts that originated in 8-bit CP/M. This thread has long since strayed from the original title.

Was'nt Concurrent Dos a DRI product? And did evolve from Concurrent CP/M -86 as I understand it. I'm open to correction on this.
You can get a copy of one of it's descendants here- http://www.digitalresearch.biz/Software.htm and have a play. The later IMS Real32 version 7.92 supports Fat32 file systems.
This site may be interesting to anyone interested in early personal computer operating systems in general- http://www.digitalresearch.biz/index.htm

You can always start another thread ol bean. Telling another member what they can or co not post is totally wrong imho.
necro posting is against forums unless it relates the the thread topic which is:-

OMG thank you Al Kossow for the necro heads up in this thread. I've brought up Altairz80 simh once again running CompuPro Concurrent DOS 3.1 to read these Concurrent DOS 4.1 5in images and this is a gold mine !!
I don't know if this will apply to the CompuPro model 10 but EVERYTHING is in here for my CompuPro 8/16 to fully build CDOS 4.1. Again, I had to boot CDOS 3.1 to read these CDOS 4.1 disks as K: and L:

That particular set of CDOS 4.1 disks is for building an OS that runs on CompuPro's S100 systems. It won't work for the CompuPro 10.
The file archive you referred to, however, happens to include a ZIP file that includes a set of CDOS v5 system disks for the CompuPro 10. That is what I provided to the original poster to the discussion, which allowed them to access their machine after being locked out by the password set by it's previous owner. The ZIP file also includes the ENTER.CMD utility and HARDDISK.DAT file which are required to reformat the hard drive.

As a comment to an earlier post--MP/M assigned user areas to users by default. User 0 was reserved for "system" files. There were some CP/M 3.0 programs that used user areas extensively.
