Switch on an Apple //e

Back to the activities

The Apple //e of 1983 was the Apple II for the rest of the decade, and the one that sold the most. It kept the slots and the software of the Apple ][+ and fixed what its owners had been adding cards for: lower case on the keyboard and the screen, 80 columns of text with a small card in a slot of its own, 64 KB of memory and 128 KB with that card. Two keys with an apple on them, Open Apple and Closed Apple, are wired to the buttons of the joystick. In 1985 the enhanced //e brought the 65C02 processor and MouseText, small pictures in the character set to draw windows and menus with.

This page switches on an enhanced //e with no disk drive, types in lower case, changes to 80 columns, shows MouseText, and runs the self test that is in its ROM.

What you need

Only izapple2: the ROM of the enhanced Apple //e comes inside it.

The Apple IIe Owner’s Manual is on the Internet Archive.

The machine

An enhanced Apple //e with no disk drive:

the 65C02 processor at 1 MHz and 128 KB of memory: 64 KB on the board, the top 16 KB of it the memory of a language card, which izapple2 puts in slot 0, and 64 KB more on the extended 80 column card, in the auxiliary slot;
no cards in its slots.

The model 2enh of izapple2 has this machine, with 8 MB more of memory on a RAMWorks card, a No-Slot Clock, a VidHD card, a FASTChip accelerator and a Mockingboard more:

Switch it on

Start izapple2 with the command above. The //e writes Apple //e at the top and goes to Applesoft. The cursor is a checkerboard.

Lower case

Type in lower case, each line with Return:
```
print "Hello, //e"
10 for i = 1 to 3: print i; " lower case": next
list
run
```
The text between quotes stays as typed. Applesoft takes its words in lower case too, and keeps them in capitals, as list shows.

80 columns

Type PR#3. The firmware of the 80 column card, which answers as if it were in slot 3, takes over the screen: twice as many characters in a line, half as wide. Type HOME and LIST: the program fits in one line now.
Show the MouseText characters: with 80 columns on, Escape, CHR$(27), turns them on, and the capitals and symbols printed in inverse come out as MouseText; Control-X, CHR$(24), turns them off.
```
PRINT CHR$(27);: INVERSE: PRINT "@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_": NORMAL: PRINT CHR$(24);
```
These are the pieces Apple II DeskTop draws its windows, its scroll bars and its check marks with.

The self test

Hold down both Apple keys and press Reset. In izapple2, the Open Apple is the left Alt or Option key, the Closed Apple the right one, and Reset is Control-F2. Let go of them after a moment.

The //e tests its memory and its chips, filling the screen with patterns in the low resolution graphics while it does.
Wait. After about half a minute in izapple2, the result:

A //e with a fault said what had failed instead.

What next

Switch on an Apple ][+ is the machine before the //e, all capitals and 40 columns. Apple II DeskTop puts MouseText to use.
