Apple released the Apple IIc in April 1984, billing it as a portable Apple II, because it could be easily carried; however, it lacked battery power and a built-in display. The IIc even sported a carrying handle that folded down to prop the machine up into a typing position.

The Apple IIc was the first Apple II to use the updated 65C02 processor, and featured a built-in 5.25" floppy drive and 128 KB RAM, with a built-in disk controller that could control external drives, composite video (NTSC or PAL), serial interfaces for modem and printer, and a joystick/mouse port. Unlike previous Apple II models, the IIc had no internal expansion slots at all, this being the means by which its compact size was attained.

The final Apple II model was the Apple IIc Plus introduced in 1988. It was the same size and shape as the IIc that came before it, but the 5¼" floppy drive had been replaced with a 3½" drive, the power supply was moved inside (gone was the IIc's "brick on a leash" power supply), and the processor was a fast 4 MHz 65C02 processor that actually ran 8-bit Apple II software faster than the IIGS.

ADTPro for the IIc

This is a way to transfer data from that old Apple 2c to a modern PC. ADTPro is a SourceForge project.

Note that the original IIc motherboard is not able to operate the serial port at speeds higher than 300 baud, making serial transfers with that version unsupported. You can check the revision of your IIc by checking memory location 64447:

  • if PRINT PEEK(64427) returns 255, you have an original IIc (ROM revision '255').
  • if PRINT PEEK(64427) returns 0, you have an IIc with UniDisk 3.5 inch drive support (ROM revision '0').
  • if PRINT PEEK(64427) returns 3, you have an IIc with memory expansion support (ROM revision '3').
  • if PRINT PEEK(64427) returns 4, you have an IIc with a modified/fixed version of memory expansion support (ROM revision '4').
  • if PRINT PEEK(64427) returns 5, you have an Apple IIc Plus (ROM revision '5').
