This is the source code for the Ohio Scientific Superboard II /
|
|
Challenger 1P / Model 600 ROMs, including the monitor, boot program,
|
|
keyboard scan routine, and BASIC.
|
|
|
|
The source code came from various sources including disassembly of the
|
|
ROMs.
|
|
|
|
This version builds with the CC65 assembler. In some cases I have also
|
|
added additional comments to the code.
|
|
|
|
Included here are a couple of optional patches to BASIC. One fixes the
|
|
display of error messages, and the other addresses the well-known
|
|
garbage collection bug.
|
|
|
|
On a Linux system with the CC65 assembler installed, you can build
|
|
everything by running "make" in this directory. Do "make patch" to
|
|
apply the two patches to BASIC. See the Makefile for more details.
