Re: Apple 2c Variants



The iiC's that support a 3.5 inch drive merely have a different rom in 'em - BUT they will ONLY supprt a UNIDISK 3.5 (rare) as oppsed to the apple 3.5" drive (more common)

The unidisk 3.5 has extra hradware in it - acutally has it's own 6502 cpu in the drive case!

Hi all,

Just a quick question about the different varieties of Apple 2c's.

Not counting the 2cplus, what are the *physical* differences in
the various 2c machines between those that support the UNIDISK,
and those that don't?

Is it simply a ROM upgrade to support the UNIDISK 3.5, or are there
some other hardware differences involved?

Has anyone managed to get the Apple3.5 drive (from a GS for example)
working on the 2c with an appropriate driver? Or is there a 2c variety
that supports it out of the box?

Many thanks in advance,
Leslie
