However, those emulators which support the Z80 (EMU][ Development - 
Unreleased and Apple Oasis being the only 2 I know of) emulate the 
Softcard, and I think the Softcard prolly has more of an installed base. 
 Hence, my preference to work toward that.  (As for block devices, I'd 
like to have support for 1.4 MB disks be in a format that can be read by 
144FEAT, which is a 1.4 MB support add-on for CP/M-86 1.1 - and the 
format is also supported afaik by John Elliott's hack of DOSPLUS.)
