Hi Warren,

Following on from the recent posts on the passing of John Walker and his
Unix-like operating system, I’m forwarding the below. The manual gives
some idea of the similarity to Unix.

Next to the kernel, there is set of system libraries, similar to the Unix stdio
and math libraries. Of course it has a shell program. The user land software
list is:

"debug": debugger similar to "ddt"  
"asm": assembler
"edit": editor similar to "ed"  
"window": editor similar to "vi"
"word": formatter similar to "nroff"
"meta": META 2 generator, similar to TMG
"spl": compiler for "system programming language", similar to PL/M
"pascal": Hansen sequential pascal
"basic": basic interpreter, similar to MS basic
"spell": spell checker, similar to Unix namesake
"qbasic": basic compiler, similar to C-Basic on CP/M

Manuals for all of these have survived, as have binaries. For most of the above
user land no sources have been found yet, only for the "window" editor and for
"pascal".

Wbr,

Paul
