Has anyone seen or (even better still) got a copy of the software and/or User Manual for the Cromemco MULTI-USER BASIC by any chance?
Tried all of the usual websites...

Are you "into" Cromemco computers by any chance? It is interesting to find quite a few people within the UK with a knowledge of Cromemco machines.

As far as I can tell from the information I have found, the MULTIUSER-BASIC (along with the integrated Disk Operating System) lived in the top 32K of the Z80 memory space.
The lower 32K of the memory space was bank switched (using the bank switch facilities of the Cromemco 16KZ and 64KZ memory boards) to support a separate memory space for each "user". I believe one lower block of memory was still required for the 'system'?
Each user had their own terminal.
I believe the BASIC must have some form of scheduler to switch between users and that various BASIC commands can be configured to prevent some 'users' from affecting the 'system' and other users. The BASIC must have come with the usual commands (PEEK, POKE etc.) that could have major undesirable repercussions within a multi-user environment... The ability for the system manager to deconfigure these types of commands would be a major positive - certainly in a business setting.
I am not sure how many users the BASIC supports or anything else (hence the interest in the manual and software).
Hi,
Thanks for responding.
I partially received your PM. The email I received as a result of your post contained the initial partial contents of your message. But, when I tried to inspect your message from within VCFED it was blank. For the mods. this may help them try and identify why some messages are appearing blank and others not? It is interesting that I received part of the message in my email though.
I don't post things to VCFED because of the size limit. In addition, VCFED is not really a platform for disseminating this type of information.
What I do is to scan a document, store it on my Google drive (other platforms are available) and send the Documentation Wizard (Al Kossow) an email with a link. Al will then "hoover it up" and put it onto Bitsavers for posterity and the benefit of the the vintage computer community.
Thanks in advance for sharing.
