Z80 Card: A circuit board containing a Z80 microprocessor. An Apple IIe equipped with a Z80
card can run programs based on the popular CP/M operating system.
Apple II Family Differences
There are thousands of programs for the Apple II family of computers.
Running Apple II Plus Programs on an Apple IIe
Here are some of the idiosyncracies involved in running a program designed for the Apple II
Plus on an Apple IIe.
Programs designed for the Apple II Plus don't recognize lowercase characters. Press down Caps
Lock and the program should run just fine.
The Apple II Plus didn't have DELETE, so programs designed for the Apple II Plus won't respond
when you press DELETE.
The program will tell you some other way of deleting characters.
The Apple II Plus didn't have UP-ARROW or DOWN-ARROW, so programs designed for the Apple II
Plus won't move the cursor up or down when you press these keys.
The program will tell you
some other way of moving the cursor up and down.
Running Apple IIc Programs on an Apple IIe
Here are some of the idiosyncracies involved in running a program designed for the Apple IIc on
an Apple IIe.
Apple IIc programs may refer to your built-in disk drive. To you that means drive 1.
Apple IIc programs may refer to the printer port, the mouse port, or the communication port.
The printer port is comparable to a printer card in slot 1.
The mouse port is comparable to a
mouse card in slot 4. The communication port is equivalent to a communication card in slot 2.
Apple IIc programs may refer to an 80/40 switch. You can get an 80-column display by adding an
80-column card to the AUX. CONNECTOR slot.
Some programs designed for the Apple IIc may require 128K. The Apple IIe comes with 64K, but
you can run such programs by adding an extended 80-column card to the AUX. CONNECTOR slot
inside your Apple IIe.
Running Older Apple IIe Programs on Your Apple IIe
The Apple IIe has been enhanced so that you can take advantage of software developed for the
Apple IIc software that runs faster and has better graphics than was possible on earlier models
of the Apple IIe.
The enhancement, which involves four chips on the main circuit board, does
not in itself give you improved graphics and speed. You must use software that takes advantage
of the enhanced features.
