Is there a list of floppy disk drives which could read and write both 3.5"
1.44mb and 720k diskettes?
A product line of musical instruments (General Music/Ahlborn-Galanti) I
service use 3.5" 720K DD floppy disk drives.
I've never had any problems formatting or backing up data files prior on
Originating in 1960, Lisp is second only to Fortran as the oldest
programming language still in use today. Historically used for research,
artificial intelligence, and mathematics, Lisp remains relevant in these
fields, as well as in quantum computing research and other cutting-edge
applications.

Replace any SMD electrolytic caps on the drive pcb if there are any.

Absent any alignment issues, or dirty heads, just about any HD drive
(e.g. Teac FD235HF) is equally facile in both DD and HD media. Quit
This is great to see. One note, you'll need to install libx11-dev (on
Ubuntu 22 anyway)
then build it. Now to figure out how to play with it.
thanks

Here is a hello world:
(format t "Hello, World!")
It kinda works, need to throw maybe a \n on it, no idea what options format
takes.
It kicks you to the debugger pretty quick, where you get to find out you
need to go read the usim documentation on key mappings, unless you have a
knight or space

often, a DD-only (e.g. Teac FD235F) drive will have performance inferior
to that of the HD-DD drives.

Yes, those are not the drives you want.
None of those exceptions.
I was merely listing sone of the weird ones to avoid (or use for weird
stuff)
IF I remember correctly (unrefreshed dynamic wet-ware RAM), 34 pins of the
40 pins of the PS/2 drive were the same, and the other 6 pins had the
pow

Do it like this:
(format t "~&Hello, World!~%")
Looks like Common Lisp documentation works for the System 100 FORMAT:
