Re: Since then...
...The 5100 and 5110 did have an 8" floppy - IBM didn't adopt a 5.25"
until the PC. The difference between the 5100 and the 5110 was one had

BTW, while looking for another book in my "dungeon", I ran across the
THE digital LOGIC HANDBOOK 1966-67 EDITION - FLIP CHIP (TM)
MODULES (c) 1966
digital SMALL COMPUTER HANDBOOK (c) 1967
THE digital PDP-8/L USERS HANDBOOK (c) 1968
pdp11 04/34/45/55 processor handbook (c) 1976
Since the first three predate my Delta/computer days, I think I picked
them up at a used book sale at some point. One of them has a library
loan card jacket in the back (but it doesn't identify the library),
another has "P. $1.00" stamped inside the front cover. I think that one
may have come from Barnes & Noble's sale annex in NYC. The fourth book
(on the pdp11) was originally from the Alexis I.duPont School District,
as it has their stamp inside. I used to get old books and Scientific
Americans from their library when they were about to throw them away.
It was from that last book (or one like it) that I first learned
machine/assembler code and system architecture.
