Matze udelal daughterboard

O: Aa3000 (a3000+)

Vubec jsem netusil, ze neco takoveho bylo.

Me prekvapuje, ze se snazili na tu zakladni desku nacpat tolik veci (SCSI, nejaky audio dekoder....), kdyz bylo mozne to do podobnych "velkych" Amig udelat jako pridavne karty. Jen si to komplikovali.

O: Aa3000 (a3000+)

Hese dnes predstavil sve dalsi veledilo AA3000+



The specifications of the AA3000+ motherboard are:
- Amiga 3000 motherboard with AGA chipset
- on-board 68030 PGA CPU and 68881/68882 PLCC FPU running at 25MHz
- DSP processor (AT&T DSP3210)
- CPU slot for A3000/A4000 accelerators
- 16MB Fast RAM using two SIMM modules (no expensive ZIP RAM chips needed)
- 2MB Chip RAM (no expensive ZIP RAM chips needed)
- extended Fast RAM support (up to 64MB?, work in progress)
- extended Kickstart ROM support up to 4MB
- on-board full 24bit AGA scandoubler / flicker fixer
- support for two external video inputs (for example a graphics card and another scandoubler such as Indivision AGA)
- monitor switch between the video inputs, similar to Ratte monitor switch (controllable by software or external switch)
- 23-pin DSUB port for native Amiga RGB video output
- 15-pin VGA port for graphics card or scandoubled / native Amiga RGB video output
- 2x stereo audio RCA jack
- SCSI-II controller (50-pin internal port, 50-pin DSUB external port)
- 880kB / 1.76MB Amiga floppy drive port (34-pin internal port, 23-pin DSUB external port)
- 2x 9-pin DSUB Amiga mouse/joystick ports
- 5-pin DIN Amiga keyboard port
- 25-pin DSUB serial port
- 25-pin DSUB parallel port
- battery backed up clock
- 2x power connectors for fans (1x +5V fan, 1x +12V fan)



AA3000+ Firebird Daughterboard

I have also designed a daughterboard for the AA3000+, called the Firebird.
The Firebird has support for 3.3V and 5V PCI cards, the PCI support is based on the Prometheus PCI bridge by Matay.

The specifications of the Firebird daughterdboard are:
- 3x PCI slots (3.3V and 5V cards)
- 4x Zorro III slots
- 1x AGA video slot

O: Aa3000 (a3000+)

tak to je velka parada, ved to bola v mnohom lepsia masina nez A4000 (16bit zvuk s DSP)

CKtwo@a1k dnes oznamil, ze se mu podarilo ziskat od Eric Lavitsky podklady pro programovani DSP3210 na Amize.

• dsp3210.device
• dsp3210.resource
• vcas.libaray

- Tests, Demos, CODECs (vcetne vserikajiciho nazvu adresare MPEG

Rysuje se moznost vyuziti DSP karty z ultrazvuku ATL HDI1000, ale predevsim pak DSP cipu integrovaneho na zakladni desce AA3000 / A3000+
