here starts a little course about Amiga CD32 games development...
I hope that little tricks coming from past will help for the future of great Amiga machines.
- two joy ports
- S-video jack
- composite video jack
- RF output jack
- stereo audio jacks
- keyboard connector
- full expansion bus
- volume control switch
- headphone jack
- external brick power supply
- internal mpeg full motion video (FMV) expansion capability
- optional computer module
- multiple session disc capability
it is roughly 6" by 12" and is a 4 layer board...
On the main PCB is a 14Mhz Motorola 68ec020, the AA chipset, an ASIC called AKIKO, a DAC for playing standard CD audio and a small amount of EEPROM.
Akiko...some words about this revolutionary chip...: it is a 160-pin PQFP surface mounted device containing most of the remainder of the logic necessary in the Amiga CD32; it includes the CD-ROM control logic and the system timers.
EEPROM has a 8K bits size to store settings, high scores, bookmarks etc.
A pal or ntsc modulator is included on board.
The compact disc DAC is a standard 18 bit, 8x oversampling DAC. Along with the superb audio quality of the DAC, the Amiga CD32 expansion connector has digital audio input capability in order to mix an external spurce such as MPEG audio with the CD audio and Amiga audio.
- 256 colors out of 16 million in all resolutions
- 32 bit wide chip RAM and support for page mode DRAMs
- 8-bit HAM mode support (near true color display)
- sprites are up to 64 bits wide
- sprites can be displayed in the borders
- attached sprites are available in all resolutions
- dual 4-bitplane playfields
- hardware scan-doubling support
- hardware compatibility mode with the older Amiga ECS chipset
- four-voice, 8 bit audio with variable sample rate
