## Preface:
|
|
Because 68000 based Palm devices are barely faster than the
|
|
Apple ][, emulation performance may be less than stellar. An
|
|
overclocking utility will go a long way to make the emulator
|
|
more useable on anything less than a 66Mhz Clie 665C.
|
|
|
|
## Introduction:
|
|
What would be better than being able to take your beloved Apple
|
|
][ with you, including most of the software you had for it, all
|
|
in your pocket? Here is your chance. The Appalm ][ emulator
|
|
brings a 64K Apple //e, no 80 column card, and 2 disk drives,
|
|
to your Palm OS based PDA. Disk images can be uploaded into the
|
|
internal Palm memory or a memory card (think how many 140K
|
|
floppies fit on a 128 MB memory card :-) ) Joystick emulation
|
|
is provided using the hard keys available on most Palm PDAs. If
|
|
you have one of those Zires without all the keys, then life
|
|
sucks for you. The Sony HIRES screen is supported (in color!) -
|
|
and looks great too. The Sony Game Controller works very well.
|
|
Highly recommended.
|
|
|
|
## Installation:
|
|
You need to install the emulator, appalm.prc, plus the ROM
|
|
files apple2e.rom and slot6.rom. Pick a disk image (currently
|
|
must be .DSK fomat) and use the DSK2PDB utility to create a
|
|
PalmOS DB of the disk image. A '-r' flag can be passed to
|
|
DSK2PDB to create a nibblized disk image which can load
|
|
slightly faster on the Palm but takes up 220K vs 140K for the
|
|
raw data. The standard format database performance has been
|
|
improved to the point where I don't know why you would want the
|
|
raw format.
|
|
|
|
## Running:
|
|
The basic features of the emulator are available through the
|
|
menu. Special keys and joystick options are settable there. You
|
|
can return to the Palm Launcher and run other applications.
|
|
When you come back to Appalm, it is in the same state as when
|
|
you left it. Some of the Palm buttons have been hijacked to
|
|
provide useful feature for the emulator. They are:
|
|
Calculator - ESC key
|
|
Find - CTRL-C
|
|
Appointment - Joystick button (1 or 2)
|
|
Memo - Joystick button (1 or 2)
|
|
Phone/ToDo - Joystick X axis
|
|
PgUp/PgDn - Joystick Y axis
|
|
A type-ahead buffer is implemented for use with an external
|
|
keyboard. You can keep typeing without losing characters.
|
|
|
|
## Development:
|
|
This is a very preliminary version meant more as a
|
|
proof-of-concept. More features and performance will be
|
|
improved upon. Disk performance is very good now and writing to
|
|
the disk image is supported. Sound support would be nice if I
|
|
could figure something workable out. Color support for lo-res
|
|
(160x160) Palms is in the works.
|
|
|
|
## Conclusion:
|
|
I wanna say thank you to David Schmenk for enhancement of Emulator
|
|
and prepare all the works of Appalm][.
|
|
|
|
And I can thank Hilary for doing all the initial development
|
|
that laid the groundwork for my work. Its much easier if you
|
|
have something that already works when developing new emulation
|
|
components.
