Apple *does not* use a hard sectored format. Its uses a 16 sector format
which *does not* use the index hole, thus soft sectored. Software is
able to find any given track/sector without the aid from the hardware.
When using a communications program on the Kaypro (i.e. modem7 or mex)
and Apple (i.e. ASCII Express "The Professional), avoid using the xmodem
(Christensen) protocol if possible. Invoke the Apple's comm program to
list the file and copy the data into the buffer of modem7 or mex. Protocol
is possible, but the file has to be processed after the transfer.
Apple's method of terminating a line in a text file is just a carriage
return -- with no linefeed. So when you type the file out in CP/M, every
line will be overwritten. Solve this by processing the file with FILTEX
(a public domain program) or some other utility that inserts a LF after
every orphan CR. Likewise, a CP/M text file transferred to an Apple will
contain that *normal* LF and appear double-spaced when listed.

Two popular CP/M cards are available for the Apple: the "Softcard" by
Microsoft and the "Appli-Card" by PCPI. They sell for about $275.00.
Each card comes with a utility disk that includes a program to convert
DOS files to CP/M.
