 Yep
 The earliest 1.2M drive that I saw (before the AT)
 was a Mitsubishi 4854? I was told that it had had
 been designed for the explicit purpose of replacing
 8" drives.  It did NOT also have a "360K"
 mode.

 I also heard a rumor (probably not true) that "When
 Microsoft was writing the DOS and AT BIOS support
 for 1.2M drives, they thought that IBM had
 decided to release a model with 8" drives".  
Cool info! Thanks!

...
  Hmmm. mixing single density sectors and double
 density sectors on the same track? 
No, but one could replace the boot sector with the
correct density boot sector when copying the disk to
make it boot on one system or another. It may have
been Vernon Hestor's other OS. V-DOS I think it was
called.

It was a cut-down Multidos he wanted to market to game
manufacturers.

  This'll make your day,...
 I had an LNW. (also a Lobo expansion interface, a
 PMC81, etc.) 
I never saw a Lobo Max-80, though I had a few friends
who bought the Mapper board from them to run CP/M on
their Model I's.

...
  Most of that stuff, I sold cheap at VCF (which is
 run by your buddy Sellam). 
He made a comment to me a month or so ago that
indicated he at least KNEW what an LNW-80 was...

Oh well..

An ex-employer (and former LNW Dealer) had several
that he trashed. I found out when I called him to ask
if he would sell or trade any away...

Bummer!!!

Thanks for the cool info!
