This project is to be an Apple III Plus. The process of locating all the schematics, firmware images and ASICs is currently underway. Once we have all the material needed to define the system we hope to commence work.
The Apple III and the III Plus
The Apple III+ project is expected to comprise of a single .zip containing an Altium Project and several pre-compiled bit stream images ready to download. The III+ project will support cross vendor targets including the Xilinx XC3S1500, the Altera Cyclone II as well as the Xilinx Virtex 4 SX and LX devices.
The soft AIII+ will offer the features of a standard AIII+ configuration:
- 512K RAM
- 6502B CPU (2MHz)
- PS2 Keyboard
- PS2 Mouse
- Compact Flash Card Interface (ProFILE)
- 640x480 VGA display
- Z80 Softcard
- Disk ][
- Support for four Apple III Peripheral Boards when used with PB10
- Optional Accelerator (when used in conjunction with a Virtex 4).
The Apple III+ project is in it's preliminary stages, and is only being laid out at this point. Sourcing information for the design has become a time-consuming task, as information specific to the III+ (as opposed to the III) is difficult to locate. If you have any information on the III+ that you would be happy to share, it would be much appreciated.
