Sample Programs
|
|
----------------
|
|
|
|
1. hello.prg
|
|
|
|
When loaded at address $0300, this program will print "Hello, 6502 World!" in
|
|
infinite loop.
|
|
|
|
2. echo_poll.prg
|
|
|
|
When loaded at address $0300, this program will echo back to the console
|
|
anything typed.
|
|
|
|
|
|
Both hello.prg and echo_poll.prg were assembled with the Ophis assembler:
|
|

|
|
|
|
3. echo_irq.rom
|
|
|
|
This is another echo program, and behaves identically to echo_poll.prg,
|
|
except it is interrupt-driven.
|
|
|
|
4. ehbasic.rom
|
|
|
|
This is Lee Davison's Enhanced 6502 BASIC.
|
|
|
|
To use this ROM image, just copy the file 'ehbasic.rom' into the directory
|
|
where you run Symon. Rename the file to 'rom.bin'. When you start Symon,
|
|
the ROM file will be automatically loaded at address $d000.
|
|
|
|
Click the "Run" button and EhBASIC should automatically start running.
|
|
|
|
Type 'C' to do a cold start.
|
|
|
|
Then, type $C000 when prompted for the memory size.
|
|
|
|
NOTE: EhBASIC only wants upper-case input. This confused me at first!
