The Apple/// uses a 6502 microprocessor, just like the one in the
Apple ][/+/e series. However, the memory organization of the ///
is different, partly because the machine supports up to 512K of
memory.
The built-in disk drive of the /// is the same as the Disk][, with
all that implies (sloth, small capacity,...:]). The /// has a
built-in emulation mode, making it look internally like a 48K Apple][,
or ][+, with a serial card in slot 7 (or something equally "unstandard",
if such a word can be applied to earlier Apple][s). The /// has three
slots, identical to slots 1-4 in an Apple][.
Programs written in in Apple/// Business BASIC can be converted to
run under BasciA or whatever under MSDOS without too much trouble.
Certainly less than from Applesoft. Graphics portions will most
likely have to be thrown out and redone from scratch.
For machine language...good luck. You're talking major
changes, mostly because operating system stuff is so different,
not to mention the different processor. Easier than going from
DOS3.3 to MSDOS, though.
You'll need a whole boatload of Apple/// manuals, in particular
the two SOS programmer's guides, Business BASIC Refence manual,
and Apple/// user's manuals. It will barely be enough.
For transferring data Apple///-MSDOS, you can use nearly anything
on the PC, on the ///, Apple's Access/// will work just fine.
You can either use a modem or just connect the two machines with
an RS232C-compatible cable that uses a DB25 connector on the A///
end and whatever works on the PC end.
If you need manuals for the ///, you'll probably find them from
Sun Remanufacturing in Arizona. (They usually advertise in Mac
or Apple// magazines, since they are currently selling and servicing
and supporting the Lisa/MacXL and Apple/// lines.
Good luck. (What does the /// have that the PC don't already
have three or four of, btw?)
