Changing the topic slightly ...
The scans for v0 code are in lowercase. I assume printed on TTY 37.
But why is the early PDP-7 code in lowercase?
I do see the B language code for "lcase" which converts to lowercase.
Maybe something like that was used?
(I think I saw a scan mistake showing a "B" which is probably an "8"
due
to that. See pdp7-unix/src/cmd/bc.s "dab B i".)
I didn't see anything in historical login code or manuals about
upper versus lowercase.
Any experiences about upper versus lower case to share?
When did stuff get rewritten to have both cases in code?
