<title>Agat-7/9 - specific information for cc65

<abstract>
An overview over the Agat-7 and Agat-9 and theirs interfaces to the cc65 C
compiler.
</abstract>
<!-- Table of contents -->
<toc>
<!-- Begin the document -->
<sect>Overview
<p>The Agat was a series of 8-bit computers produced in the Soviet Union from 1983 to 1993.
It was based on Apple II architecture with all electronic components made in the Soviet Union except for 6502 microprocessors supplied by UMC (UM6502A).
<p>If compared to Apple II, Agat had many improvements such as color text mode, additional graphic modes and flexible memory controller.
Agat-7 had an Apple II compatibility card called "Module 121", while Agat-9 had a built-in Apple II+ mode activated by soft-switch.
<p>All mass-produced Agat models were disk-based systems, 2K ROM contained only basic machine language monitor and disassembler.
Agat-7 had 140K floppy-drive based on Apple DISK II, while Agat-9 was supplied with 840K drive having its own sector format and controller.
<sect>Binary format<p>
The standard binary file format generated by the linker for the Agat target is
an AppleSingle file to be compatible with AppleCommander <url url="https://applecommander.github.io/">.
The default load address is &dollar;1903.
<sect>Platform-specific header files<p>
Programs containing Agat-specific code may use the <tt/agat.h/ or
<tt/agat.inc/ include files.

This macro contains a bitset that allows to check if a specific instruction
set is supported. For example, the 65C02 CPU supports all instructions of the
65SC02. So testing for the instruction set of the 65SC02 using the following
check will succeed for both CPUs (and also for the 65816 and HUC6280).

checks. The <tt/__CPU__/ variable is usually derived from the target system

<tag/Description/The actual color is an index to a palette. During tgi_init
you will get a default palette. The number of colors depend on the platform.
All platforms recognize at least TGI_COLOR_BLACK and TGI_COLOR_WHITE. But some
platforms have many more predefined colors. If you paint using TGI_COLOR_GREEN
and then you change the green of the palette to blue using tgi_setpalette then
after this painting in TGI_COLOR_GREEN will actually be blue.
you will get a default palette.
A default palette has always two entries with values equal to TGI_COLOR_BLACK
and TGI_COLOR_WHITE. However, which default palette entries have those two
values is target specific.
