The original Apple II character generator ROM had two identical sets of uppercase inverse
characters, one of which was unnecessary. In the new character generator, the redundant set of
uppercase inverse characters has been replaced with MouseText characters. This doesn't have any
effect on the way the application works, so if it doesn't bother you, go ahead and use the
application. If it does bother you and you'd like an upgraded version, see your authorized
Apple dealer or contact the developer of the application.
Peripheral Devices
Applications designed for those models of the Apple II that don't have ports may ask which slot
your printer, modem, or disk drive is connected to. You can use these applications even if your
peripheral devices are connected through ports as long as you know which port corresponds to
which slot.
Slots and ports
______________________________________________
Slot Port
______________________________________________
Slot 1 Printer port
Slot 2 Modem port
Slot 3 Text display
Slot 4 Mouse port on keyboard
Slot 5 3.5-inch disk drive in disk drive port
Slot 6 5.25-inch disk drive in disk drive port
Slot 7 AppleTalk in printer port or modem port
The Apple IIc has a built-in disk drive, so applications developed for it may ask you whether
you want to save a document on the disk in the built-in drive or on the disk in the external
drive. You can use these applications on the Apple IIgs just think of drive 1 as your built-in
drive and drive 2 as your external drive.
Applications designed for the Apple IIc may refer to an 80/40 switch because the Apple IIc has
a switch on the case that you use to alternate between an 80-column and a 40-column display.
The Apple IIgs doesn't have a switch, but you can change from an 80-column to a 40-column
display by using the Control Panel Program, explained in Appendix A.
Applications designed for the Apple IIe that require 128K may tell you that you need an
extended 80-column card. The Apple IIgs has all the functions of the extended 80-column card
built-in (and then some), so don't rush out and buy one.
Memory
The Apple IIgs has 256K RAM standard; that's more built-in memory than the Apple IIc or Apple
IIe and much more than the Apple II Plus. You can use applications designed for Apple II's with
less memory, but applications designed to take advantage of the Apple IIgs's 256K memory won't
run (or won't run the same way) on earlier models of the Apple II. Keep this in mind if you
plan to share applications with friends or business associates who have other models of the
Apple II.
Apple II Plus
Display Columns: 40; expandable with 80-column card in slot 3.
Resolution: low (16 colors, 40 by 48); high (6 colors, 280 by 192).
