Description

c2d is a small utility that will read Apple II binary and monitor text files and output a DOS ordered diskette image that will boot your code quickly.

Based on work by:

Weishaar, Tom. Running without filenames. Open-Apple Jan. 1985 Vol. 1, No. 0: p. 7 (http://apple2online.com/web_documents/Open%20Apple%20Vol1No00.pdf)

Features

• $800-$B6FF available for binary code.
  • $B700-$BFFF free after load.
• Platforms tested:
  • 32-bit/64-bit x86 MacOS|OS/X.
  • 32-bit x86 Windows/MinGW.

Build Notes

Unix/Linux:

make

or

MacOS|OS/X, Linux, Cygwin:

gcc -Wall -Wno-missing-braces -I. -O3 -o c2d c2d.c -lm
gcc -Wall -O3 -o bin/text2page text2page.c -lm
gcc -Wall -O3 -o bin/page2text page2text.c -lm

Windows/MinGW:

PATH=C:\MinGW\bin;%PATH%
gcc -Wall -Wno-missing-braces -static -I. -O3 -o c2d c2d.c -lm
gcc -Wall -O3 --static -o bin/text2page text2page.c -lm
gcc -Wall -O3 --static -o bin/page2text page2text.c -lm

c2d Usage/Examples

usage:  c2d [-vh?]
        c2d [-bgm] [-r row] [-t filename] [-s start address override] input[.mon],[load_address] output.dsk

        -h|? this help
        -m jump to monitor after booting
        -s XXXX jump to XXXX after booting
        -t filename, where filename is a 1K $400-$7FF text page splash screen
           The splash screen will display while the binary is loading
        -b animated loading bar
        -g splash page is mixed mode GR
        -r override row default of 19 with 'row'
        -v print version number and exit

Input without a .mon extension is assumed to be a binary with a 4 byte header.
If the header is missing then you must append ,load_address to the binary input
filename, e.g. filename,800.  The load address will be read as hex.

input with a .mon extension expected input format:

        0800: A2 FF 9A 20 8C 02 20 4F
        0808: 03 4C 00 FF 20 9E 02 A9

Examples:

        c2d hello hello.dsk
        c2d hello.mon hello.dsk 
        c2d hello,800 hello.dsk 
        c2d -m test,300 test.dsk
        c2d -s 7300 alpha4,400 alpha4.dsk
        c2d -t gameserverclient.textpage gameserverclient,800 gameserverclient.dsk

Splash Page Examples

Click on image to see video.

Splash pages are the exact bytes the Apple II expects in memory range $400-$7FF. Your splash screen should be exactly 1024 bytes (do not worry, the c2d loader will not over-right the Peripheral Slot Scratchpad RAM).

c2d -t gameserverclient.textpage gameserverclient,800 gameserverclient.dsk

-t gameserverclient.textpage instructs c2d to put up a text splash page while the binary is loading.

---

c2d -b -t barloader.textpage gameserverclient,800 gameserverclientbar.dsk

-b adds an animated bar on line 19.

---

c2d -b -g -r 23 -t bargrloader.textpage gameserverclient,800 gameserverclientbargr.dsk

-r 23 moves the animated bar to line 23, and -g indicates the splash page is mixed mode text/gr.

text2page Example

Input is expected to be ASCII text (LF or CRLF line terminated). Only the first 40 characters/line and the first 24 lines are read. See gameserverclient.text and barloader.text examples.

text2page <gameserverclient.text >gameserverclient.textpage

page2text Example

Input is expected to be an Apple II binary from $400-$7FF. Exactly 1024 bytes. See gameserverclient.textpage example.

Text output lines are newline (LF) terminated. Windows users may need to convert LF to CRLF (editor dependent).

page2text <gameserverclient.textpage >gameserverclient.text

Testing

Automated testing is only supported on MacOS|OS/X and requires the following:

• Virtual ][ (http://http://www.virtualii.com/)
• Windows cross-compiling tools http://crossgcc.rts-software.org/download/gcc-4.8.0-qt-4.8.4-win32/gcc-4.8.0-qt-4.8.4-for-mingw32.dmg
• Wine (http://winehq.org) installed in ~/wine (extract the tarball in ~/wine and move the contents of ~/wine/usr to ~/wine, or change the path to wine in tests/test.sh).

To test, type:

make test     # MacOS|OS/X only
make disttest # MacOS|OS/X and Windows
make fulltest # MacOS|OS/X, Windows, and Virtual ][

If Virtual ][ crashes while testing, just make fulltest again

Bugs

Yes. No input checking. Big Endian untested.
