   I'm using xtrs to emulate a Model I and can use TRSDOS 2.7D that's been   
   modified to use the Percom Doubler instead of the Radio Shack version. I'd   
   like to be able to use Radio Shack disks unmodified so I can also use TRSDOS   
   2.8D. The xtrs manual says    
   both doublers are emulated and both types of disks should work but I get a   
   disk error and no boot screen on unmodified TRSDOS disks. Is there a trick to   
   make xtrs work properly with Radio Shack double density Model I disks?
