Some time ago I advertised a copy of ACAD for the rainbow.  Someone Who
claimed to be President of DECUS called and we struck a deal to
trade for a book.  I was pretty much giving it away.  I have
not recieved anything in return and have lost the persons name.
 I can only assume that there has been a mixup or I have been
had.  If you are out ther 
, please contact me at 508 460 1643.
 
Thank you

 GT>    Ah, can you explain this? Is this due to formatting?

If you have a drive doing 96 TPI and only us 1/2 inch of disk to put
data on you would have a 48 track system.  You also could
format only ever other track.  DEC uses only par of an inch and
gets 80 Tracks.  This is why you can format IBM single sides
media in the Rainbow after bulk erasing the media (Using FORIBM
under CPM).

The question seems to be popping back and forth about drives being rated 
as "96 tracks per inch" but only having 80 tracks. This, in fact, is 
standard. The usual 40 track drives have "48 tracks per inch." No one is 
getting cheated here -- we all have been living with this since they sold 
the first 5.25" floppy. :-)
