I am looking for an operating system for an IBM 5100 or /370 line mainframe. I am only interested in the version that includes the basic interpreter.

The operating system was built in depending on if you ordered BASIC or APL or BOTH.

Just like the later Commodore CBM, PET, Vic 20 and Commodore 64 (to name a few in that line). If you want to program you'd better brush up on your BASIC or APL skills bepending on what is in your computer.

20 goto 10

IBM Public Domain Software Collection (http://www.ibiblio.org/jmaynard/)
The site contains copies of distribution tapes, other source and object code libraries, and pregenerated, runnable distributions of IBM public domain software written for the System/360 and System/370 mainframe computers.

All of the software on this site is in the public domain. IBM, by corporate policy, does not assert copyright ownership of any software which it distributed without copyright notices. US copyright law, until 1978, placed such materials in the public domain.

TSS/370, is version 3.0 of IBM's Time Sharing System/370, the timesharing system that they wanted customers to run instead of VM/370. can be found on the above site as well.

MVS 3.8J (http://ensose.com/mvs38j.html)
MVS 3.8J is the final public domain version of IBM's OS/370 MVS operating system, released in the late 1970s and early 1980s. It runs with 24-bit addressability so it can only address 16MB of virtual storage. It only supports 3 hexadecimal digit I/O addresses. Aside from those limitations, it has quite a lot in common with today's OS/390 and z/OS systems and can still perform useful work.


You might also want to get a copy of the Hercules Mainframe Emulator which you can run the above systems on
