This project is a re-implementation of the Amiga 1200 board started from the schematics. I made some changes and enhancements to the original schematics.
- All Original AA chips are needed and can be put into the sockets. These include Lisa, Paula, Alice and the two CIA chips.
- The CPU is removed, you need some accellerator board to run this board.
- The DRAM has been removed and the functionality has been moved to a daughterboard.
- Video output has been moved to a seperate output board. This board get all Lisa output signals and also all the typical Zorro signals. This means that an RTG card can be developed.
- The PCMCIA slot has been removed and in the free space a Compact Flash socket has been added.
- A 110V-240V AC-DC powersupply has been added, so no more power brick. This generates these voltages:
- 5 Volts: main power rail 5 Amp capable
- 12 Volts: 0.8 Amp capable
- two PC standard 3 Pin fan headers are added to the board.
- A non-volatile digipot has been added in the audio path, this allows you to set the stereo separation.
- Extension board connector for Mouse/Joystick/Network/FlashFloppy. (one is in development that has USB Mouse and two classic DB-9 connectors and autoswitches when fire button is pressed + ethernet)
- Replaced the keyboard controller by a modern MCU
- Dual ROM switcher
- DF0/DF1 Bootselector
