Definitely possible. It can read a RAW track, and then your software
would have to parse that to recreate the bytes and then the sector
boundaries. The details of the Apple track format are pretty well
described in "Beneath Apple DOS".

There is no readily available programming documentation for the option
board. Central Point was ultra-paranoid, and assumed that anybody wanting
to do so would be doing it for no other purpose than to go into
competition with them. (Kinda ironic, isn't it that those whose business
is copying are those most paranoid about being copied) They made me sign
Non-Disclosure-Agreements for grossly inadequate (less than 1/2 page of
useful info) and wrong info that did NOT match what was clear from
disassembly of TE.COM. Sorry, I don't know where that went when we closed
down and moved my office.
