Re: [TUHS] UniFlex

P.S. (sorry for following up to myself) I had a look into the files, and the system comes with commented source code in assembler. FWIW this is a full distribution, including development environment (C, Cobol, Fortran-77,..), editors, kernel, VSAM database, etc... all of it with source code and documentation, From my first cursory look most of it is written in assemble, comes with sample test code and is documented enough to be understandable. The pascal, cobol and fortran 77 compilers are written in pascal (!), the C compiler is written in assembler. It looks like the environment must have been only vaguely UNIX-like but yet I find it mesmerizing enough considering where it ran and when. It adds another dimension to understand the impact UNIX had and how it spun off lookalikes and sprung the imagination of developers of the time expanding its heritage sideways. j -- EMBnet/CNB Scientific Computing Service Solving all your computer needs for Scientific Research. http://bioportal.cnb.csic.es http://www.es.embnet.org _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs Wow, what a blast from the past. I used Flex on the Radio Shack Color Computer in 64MB of memory in the '80s for a while. Yes, the entire thing was assembly and some Fortran. I did not have the source to most of it for my version, only the compiled binaries. The version I used ran off floppy disks, of course, and used a strange sector layout. Something like 17 sectors of 256 bytes, instead of the 18 sectors 256 bytes that the Color Computer usually used. Neat system in some ways. Way more "professional" then is peers, except for OS/9 from Microware. Flex was only very vaguely Unix, however. OS/9, which I used a whole lot on the Color Computer and Color Computer 3, was a lot more Unix like. I understand that the 6809 version is floating around the Net. It was also all 6809 assembly, multitasking and multiuser. Very Unix V4/V5/V6 like in a number of ways. -- Brad Spencer - brad(a)anduin.eldar.org - KC8VKS http://anduin.eldar.org - & - http://anduin.ipv6.eldar.org [IPv6 only]
