|
|
|
|
==== slot
|
|
|
|
The +slot+ command inserts a card into a peripheral slot of the emulated Apple.
|
|
|
|
--------
|
|
slot <slot> <card>
|
|
-------
|
|
|
|
+<slot>+ Slot number, 0 through 7, to insert the card into.
|
|
|
|
+<card>+ The type of card to insert into the slot (see <<cards>>):
|
|
|
|
* +language+
|
|
* +firmware+
|
|
* +disk+
|
|
* +clock+
|
|
* +stdout+
|
|
* +stdin+
|
|
* +empty+
|
|
|
|
The +slot+ command inserts a card into a peripheral slot. For example:
|
|
|
|
--------
|
|
slot 0 language
|
|
--------
|
|
|
|
inserts a language card into slot zero. Use +empty+ to remove a card:
|
|
|
|
--------
|
|
slot 0 empty
|
|
--------
|
|
|
|
[NOTE]
|
|
The emulated Apple should be _powered off_ before inserting or removing cards.
|
|
|
|

|
|
|
anchor:import[]
|
|
|
|
==== import
|
|
|
|
The +import+ command imports a binary image file into the emulated Apple's memory.
|
|
|
|
--------
|
|
import slot <slot> { rom | rom7 | rombank } <base> <file-path>
|
|
import motherboard { rom | ram } <base> <file-path>
|
|
--------
|
|
|
|
+<slot>+ Slot number, 0 through 7, of peripheral card to import the binary image into.
|
|
|
|
+<base>+ Base address in hexadecimal within the given memory area at which to start loading the binary image.
|
|
|
|
+<file-path>+ Path of the binary image to import.
|
|
|
|
The +import+ command reads the binary image byte-for-byte from the given file-path
|
|
into an area of memory in the emulated Apple. You can load into either the motherboard or
|
|
a card in one of the slots. For the motherboard, you choose the RAM or ROM area. For a card
|
|
in a slot, you can choose either the normal ROM, the bank-switched ROM, or the so-called
|
|
``seventh ROM'' area.
|
|
|
|
You also have to specify the base address within the specific memory
|
|
area at which the image file will be loaded. Note that the base address is specified as the offset
|
|
within the specific memory area, and not necessarily as the actual memory address as seen
|
|
by the Apple. So for motherboard ROM, for example, specifying a base as 2DED will cause the
|
|
image to be loaded at offset 2DED in the ROM, which will be addressed by the Apple at
|
|
memory address $FDED (because motherboard ROM ``starts'' at address $D000).
|
|
|
|
For peripheral cards, the ROM will be seen at locations $Cs00-$CsFF, where s is the slot
|
|
number (1 through 7). The ``seventh ROM'' can be seen as locations $C800-$CFFF; Jim Sather
|
|
describes this functionality in
|
|
http://www.scribd.com/doc/201423/Understanding-the-Apple-II-by-Jim-Sather-1983Quality-Software[Understanding the Apple II],
|
|
on page 6-4, section ``The Seventh ROM Chip.'' The EPPLE ][ emulator handles this processing correctly. A card can
|
|
also have bank-switched ROM, which will show up at addresses $D000-$FFFF when switched in
|
|
(stealing that address range from motherboard ROM... see
|
|
http://www.scribd.com/doc/201423/Understanding-the-Apple-II-by-Jim-Sather-1983Quality-Software[Understanding the Apple II],
|
|
p. 5-26 ``The 16K RAM Card'').

anchor:load[]
|
|
|
|
==== load
|
|
|
|
The +load+ command loads a (nibble) floppy disk image into one of the emulated disk drives.
|
|
|
|
|
|
--------
|
|
load slot <slot> drive <drive> <file-path>
|
|
--------
|
|
|
|
|
|
+<slot>+ Slot number, 0 through 7, of Disk ][ controller card to load the nibble image into.
|
|
|
|
+<drive>+ Drive number, 1 or 2, of the disk drive on the controller card to load the nibble image into.
|
|
|
|
+<file-path>+ Path of the nibble floppy disk image to import.
|
|
|
|
The +load+ command will load a nibble image into a disk drive. Specify the slot that
|
|
contains a Disk ][ controller peripheral card, and specify which drive number (1 or 2).
|
|
|
|
[NOTE]
|
|
The floppy disk image MUST be a NIBBLE DISK IMAGE.
|
|
Other formats (for example, DOS order, +.do+, PRODOS order,
|
|
+.po+, +.dsk+, or anything else) must first be converted to nibble format. A nibble image contains
|
|
all 35 tracks, in order 0-36, each track being 6656 ($1A00) bytes long. Nibble image files
|
|
will generally have a filetype of +.nib+.
|
|
|
|
|
|
The best floppy disk image conversion tool I've found is http://ciderpress.sourceforge.net/[CiderPress],
|
|
for Windows (but it supposedly runs under Wine on Linux, too). Thanks to Andy McFadden.

anchor:unload[]
|
|
|
|
==== unload
|
|
|
|
The +unload+ command removes a floppy disk image from one of the emulated disk drives.
|
|
|
|
--------
|
|
unload slot <slot> drive <drive>
|
|
--------
|
|
|
|
+<slot>+ Slot number, 0 through 7, of Disk ][ controller card to which the drive is attached.
|
|
|
|
+<drive>+ Drive number, 1 or 2, of the disk drive on the controller card to remove the floppy disk image from.
|
|
|
|
The +unload+ command removes the disk from the specified slot and drive.
|
|
|
|
[WARNING]
|
|
If the disk has been modified but not saved, the modifications will be DISCARDED.
|
|
|
|
|
|
|
|
anchor:save[]
|
|
|
|
==== save
|
|
|
|
The +save+ command saves changes made on an emulated floppy disk back to the original image file.
|
|
|
|
--------
|
|
save slot <slot> drive <drive> <file-path>
|
|
--------
|
|
|
|
+<slot>+ Slot number, 0 through 7, of Disk ][ controller card to which the drive is attached.
|
|
|
|
+<drive>+ Drive number, 1 or 2, of the disk drive on the controller card to save.
|
|
|
|
+<file-path>+ Path of the nibble floppy disk image to import.
|
|
|
|
The +save+ command saves any changes that the emulated Apple ][ has made to the floppy
|
|
disk image. It is important to note that the emulator operates on the image only in memory, and does
|
|
not immediately write changes back to the real file. You need to issue the +save+ command
|
|
in order to write changes back to the file. Note that the emulator will display a asterisk +*+
|
|
next to the file-name of a disk image if it has any unsaved changes.
|
|
|
|
|
|
|
|
anchor:cassette[]
|
|
|
|
==== cassette
|
|
|
|
The +cassette+ command performs various operations of the emulated cassette tape.
|
|
|
|
|
|
--------
|
|
cassette new <file-path>
|
|
cassette load <file-path>
|
|
cassette unload
|
|
cassette rewind
|
|
cassette save
|
|
--------
|
|
|
|
+<file-path>+ File path of the (special format) cassette tape image file.
|
|
|
|
The +cassette+ command allows the user to control the emulated cassette tape player.
|
|
See <<cassette_tape>> for more information about operating the emulated
|
|
cassette player and cassette tape image files.
|
|
|
|
|
|
|
|
anchor:revision[]
|
|
|
|
==== revision
|
|
|
|
The +revision+ command specifies which revision of Apple ][ motherboard to use.
|
|
|
|
--------
|
|
revision <rev>
|
|
--------
|
|
|
|
|
|
+<rev>+ Revision number of the motherboard. Currently, only two values make any difference in behavior: 0 or 1.
|
|
|
|
The +revision+ command chooses which revision of the Apple ][ motherboard to
|
|
use. The only revisions that make any difference (for now, at least) are 0 or 1. Zero
|
|
is the original (now quite rare) version of the motherboard, that only had two hi-res
|
|
colors (green and purple), and always displayed text with green and purple fringes.
|
|
Revision 1 and later motherboards are the ones we are more familiar with.
