Officially I think there has to be a conversion. If it works, with
your modem and TOS, I think your cable will be ok.

Can't you find about 20Mb of space? I think this will suffice to build
an atari kernel. You only need the general kernel sources and the
arch/atari & arch/m68k trees. The rest of the arch tree and most
of compat and dev can be removed.
Otherwise, drop me the clock values for RTxCA and TRxCA. If they
are different than the values in zs.c, I'll send you a kernel to
test it.

Leo.
