OVERVIEW

SG C Tools ANSI C library unlocks the power of the C128 running
CP/M!  High level and low level functions are included to access
the VDC, SID and CIA.  All source code is compatible with the
Freeware version of Hi Tech C.  A demo is included to show you how
to use most features.


REQUIREMENTS

A C128 or C128D running CP/M 3.0 or a IBM PC running a CP/M
emulator and DOS to CP/M file transfer software.

At least one 1581, two 1571s, large RAM disk or hard drive to
compile on a C128.

80 column monitor for VDC specific routines.  640 X 480 interlace
graphics requires a monitor that can handle this format.

ANSI C programming experience.


MODIFICATIONS IN VERSION 1.5

It took me a while to release this version due to work on another
project.  I'm developing a Paradox 4.x browser for DOS and DOS
Protected mode, so I haven't had much hacking time for the C128.

Added pixel, line, ellipse and text functions for VDC 640 X 480
interlace bit map mode.

The 640 X 480 ellipse function leaves gaps with some radiuses.  I
ported this from a Pascal SWAG packet that was intended for 320 X
240 X 256 (Mode X) VGA displays.  I may have not been intended for
resolutions greater than this.  It seems to work fine in 640 X 200
though.  I have included the source for this, so you can play
around with it if you want.  Remember, I will give you a free
registered copy for a fast integer based ellipse function which I
can include in SG C Tools.

Unregistered versions no longer include library source!
