One thing I haven't seen mentioned is QNX - I didn't directly use it but a colleague was using it in the mid-1980s on PC-AT class hardware. ISTR one of my colleague's whinges was the 256-byte command-line limit. My earliest exposure would have been Xenix on a 286 - my main recollections are: 1) The Pascal compiler that didn't ignore comments (changing a comment could make the code fail to compile with an obscure error. 2) The fork() system call could sometimes return -1 to the parent, even when it succeeded - that caused a lot of head-scratching. 3) Hacking one of the Emacs clones (I no longer recall which) to use "far" pointers for the buffers, so I could edit files >64K without paying the performance penalty of writing "large model" code. (286 protected-mode performance was abyssmal if it needed to do segment descriptor loads) Unfortunately, I no longer have that code. -- Peter Jeremy -------------- next part -------------- A non-text attachment was scrubbed...
