An Apple technical note > makes reference to Appletalk firmware in a IIc. The FAQ says > there is no such functionality. What is the firmware about then? The AppleTalk firmware was provided in the "UniDisk" version of the IIc ROM. It doesn't actually implement any AppleTalk protocols: it just provides support for routing ProDOS calls to an external box that would have plugged into the disk port (if I recall correctly). This box would have basically been a self-contained computer that implemented the AppleTalk protocols and provided buffering. In effect, the box would contain similar hardware to the Apple II Workstation Card (a 65C02, a Z8530 SCC, and its own RAM and ROM). The box was never released, and Apple removed support for it in later versions of the IIc firmware. There may have been technical reasons for its non-appearance, but I can't think of any off-hand. -- David Empson dempson@actrix.gen.nz Snail mail: P.O. Box 27-103, Wellington, New Zealand
