The edit history in the handlers/*.pal reflect the driver changes, and 
there's also a pile of useful changes to the installer, etc.  The github 
per-file check-in comments aren't always that helpful.  The "history" 
button in the upper right gives perhaps the best synopsis of the changes 
on a "per commit" level.

If "RES/E" doesn't report version "I", you aren't running the latest.
(Kyle's code was through "E", Bob's code  was "F", CJL's code was "G" 
and "H", and my KIE fix is "I".)

I also have lying around somewhere a bootable SerialDisk image I made 
with LINCtape drivers, which I hope to actually run on my -12 someday.

CJL had some ideas about a SerialDisk for PQS?8 and other non-OS/8 
operating systems, but I haven't seen any code for that.  (I also 
disagree with his ideas about the need to switch to 128-word blocks.)
