apple2.c - Apple II/II Plus and clones
Next generation driver written in September/October 2014 by R. Belmont.
Thanks to the original Apple II series driver's authors: Mike Balfour, Nathan Woods, and R. Belmont
Special thanks to the Apple II Documentation Project/Antoine Vignau and Peter Ferrie.
II: original base model. RAM sizes of 4, 8, 12, 16, 20, 24, 32, 36, and 48 KB possible.
8K of ROM at $E000-$FFFF, empty sockets for $D000-$D7FF and $D800-$DFFF.
Programmer's Aid #1 was sold by Apple for $D000-$D7FF, some third-party ROMs
were also available.
Revision 0 (very rare) had only 4 hi-res colors (blue and orange were missing).
Revision 0 boards also did not include a color killer in text mode, making text
fringey on color TVs/monitors.
ROM contains original non-autostart Monitor and Integer BASIC; apparently
Autostart + Integer is also possible.
II Plus: RAM options reduced to 16/32/48 KB.
ROM expanded to 12KB from $D000-$FFFF containing Applesoft BASIC and
the Autostart Monitor. Applesoft is a licensed version of Microsoft's
6502 BASIC as also found in Commodore and many other computers.
Users of both models often connected the SHIFT key to the paddle #2 button
(mapped to $C063) in order to inform properly written software that characters
were to be intended upper/lower case.
Both models commonly included a RAM "language card" in slot 0 which added 16K
of RAM which could be banked into the $D000-$FFFF space to replace the ROMs.
This allowed running Applesoft on a II and Integer BASIC on a II Plus.
A II Plus with this card installed is often called a "64K Apple II"; this is
the base configuration required to run ProDOS and some larger games.
