Well, if you have the softcard docs there are a pair of programs to copy
via serial line program from another CPM crate. they were called up and
down.

No! Apple with softcard was a hybrid and the IO used the 6502 to do
serial, disk, screen and other handy things. Most CPM comm programs like
I'd said were the worst offenders for using the hardware directly.

The best way is to look at the up and down programs if you have them as
they are simple and do the basic work to communicate with asystem with a
similar program (they are very trivial). Unfortunatly I don't ahve the
the original version of them and the ones I use are very different so I
can't help there. But, Even the fancy versions I run are less than
300 bytes! The Apply ones were some 200 or so and easily hand entered to
DDT.
