## DESCRIPTION
|
||||
|
||||
c2t is a command line tool that can convert binary code/data and/or
|
||||
Apple-1/II Monitor text, as well as 140K disk images, into audio files
|
||||
suitable for use with the Apple-1 and II (II, II+, //e) cassette interface.
|
||||
`c2t` is a command line tool that can convert binary code/data and/or Apple-1/II Monitor text, as well as 140K disk images, into audio files suitable for use with the Apple-1 and II (II, II+, //e) cassette interface.
|
||||
|
||||
c2t offers three high-speed options for the 64K Apple II+ and Apple //e:
|
||||
8000 bps, 8820 bps, and 9600 bps. The c2t compression option may be used to
|
||||
speedup the delivery of data with all three as well as the native 1333 bps
|
||||
cassette interface ROM routines.

`c2t` offers three high-speed options for the 64K Apple II+ and Apple //e: 8000 bps, 8820 bps, and 9600 bps. The c2t compression option may be used to speedup the delivery of data with all three as well as the native 1333 bps cassette interface ROM routines.
|
||||
|
||||
8820 bps (used to burn CDs) and 9600 bps are not compatible with all II+s
|
||||
and //es. If you plan to distribute your audio files, then use 8000 bps.
|
||||
8820 bps and 1333 bps is not an option for disk images.

8820 bps (used to burn CDs) and 9600 bps are not compatible with all II+s and //es. If you plan to distribute your audio files, then use 8000 bps. 8820 bps and 1333 bps is not an option for disk images.
|
||||
|
||||
High-speed and compress options require c2t's custom loader, and at this
|
||||
time that limits you to a single segment. You can overcome this limitation
|
||||
by concatenating all your code together and creating your own code to
|
||||
shuffle your data around, or, pad each segment with enough zeros to align
|
||||
subsequent segments with their target address and then use the compress
|
||||
option to minimize this overhead.

Multi-segment audio files can be created for the Apple-1, II, II+, and //e
|
||||
that can be loaded using the standard cassette interface ROM routines.

WHY?
|
||||
## WHY?
|
||||
|
||||
I created this because I needed a convenient way to get data loaded into my
|
||||
//e without dragging my computer out of my office (2nd floor) to my mancave
|
||||
(basement). IOW, I needed an iPhone/iPad/mobile solution. That, and
|
||||
CFFA3000 was sold out.
