Subject: [TUHS] PDP 11/23 running UNIX version 6 at VCF Midwest!

While doing some end of year retrocomputing revisiting, I thought some
of you might enjoy this - there is hope for the next generation(s)! ;)
In this video I share my personal pick for "best" demo at VCF
Midwest: Gavin's PDP 11/23 running UNIX Version 6! We write and run a
simple BASIC program in Ken Thompson's bas(1), finding some quirks
with this (currently) entirely floppy-based system, possible having to
do with a glitch in disk I/O. (We discovered bas(1) uses a temporary
file as backing store.)

Here's the source code to the simple program we wrote; you can also
run it on modern machines if you install a Research UNIX version using
SimH (pdp-11 simulator).
5 goto 30
10 for col = 1 arg(1)
12 prompt " "
20 print "Welcome to VCF Midwest!"
30 for x = 0 55
60 for x = _56 _1
