Hi, I seriously doubt there's a "real" Unix for such a small machine from that era. There may be workalikes, of course. I know of a Unix workalike for the Commodore 64 called LUnix, but it isn't really a full Unix. That's almost (almost!) the same CPU, at least.

Does anybody know of any from back in the day? It's got a 65c02 processor and somewhere around 128k of RAM, but it's also pretty expandable w/7 slots and a huge amount of literature about how to do stuff w/those slots. My favorite 8-bit processor, maybe my favorite all around. So simple, one accumulator and two index registers but it is only 64K of total address - although with bank switching more memory could be added in 4K banks on a number of Apple II's, but you have 16 address bits and worked a register that switched in and out the 4K banks. and there is of course no protection hardware nor the concept of user/kernel in the hardware. The size of the Apple Floppy disk was rather small, and your need 3 to run things like the UCSD Pascal system to have any experience other than constantly switching disks. There are a number of C compilers available but with its limited and fixed stack (8 bits only), so it is difficult to run programs of any size (in any language - automatics are often managed off the stack). Running a full UNIX on it was not really possible although a few of the Unix style utilities were moved to it and a number of simple monitors were written that swapped programs in and out DOS style. At one time, I had a fairly good version of the Bourne (V7) syntax shell we got running, but it had to be swapped in and out slowly. That is; you run the shell, type a command, when exec is done, the shell is tossed out and the new program installed in memory.
