Re: [TUHS] Article on the history of cat(1)

In fact, the only assembler stuff I remember modifying was deep in the kernel, to take advantage of Unibus timing (on the /40 at least), where the "obvious" code was sub-optimal; can't remember the details, but it saved a bus cycle or two. Hell, I wish I still had that "CSU Tape"; it was Edition 6 with as much of Edition 7 (and AUSAM) that I could shoe-horn in, such as XON/XOFF for the TTY driver. I was known as "Mr Unix 6-1/2" at the time... Completely rewrote the 200-UT driver so that it actually worked (IanJ's driver was a horrible mess) and worked around an egregious bug on the Kronos side which they said was baked-in so deep that it couldn't be fixed. Rewrote the plotter driver and Versatec LV-11 driver to use the buffer pool instead of the character queues, so they went like a bat out of hell. Etc. -- Dave
