Charles and I have many emails over the years going back and forth regarding
OS/8 vs. P?S/8.
He was one of those folks that when you sent him a five line email, you would
often get a five page response. Charles was definitely opinionated - but often
proven to be right.
Both Charles and Merrill (author of FOCAL) teased me when I got my PDP-8/S
running. It was definitely SLOW (8/S where S=Slow). Merrill told me that DEC
management was furious when FOCAL displayed which kind of 8 it was running on.
Management wanted folks to think all 8's were totally compatible.
Charles designed P?S/8 to run in a 4K PDP-8 - making it feasible to run on a
basic 8/S (OS/8 requires a minimum of 8K). I hope it gets "released" someday :)
I'll miss Charles and his passion for P?S/8.
