Project: Graphic board as partly equipped platine for A500 and Zorro-slot
Currently Amiga-user Matthias "Matze" Heinrichs is reworking the design of a clone of a 20 years old graphic board Picasso II+ developed by Georg Braun. The final product is supposed to be working in a Zorro-Slot as well as (after removing a part of the connector block) in the expansion port of an Amiga 500:
In order to to be suitable with different cases, the VGA-port is on a separate platine which is connected with the graphic board by cable. This second platine also also can be connected with the Scandoubler Indivision. An integrated switcher automatically provides the required signal (graphic board or Indivision) to the VGA-port.
Heinrichs is going to sell the board as partly equipped construction kit: RAM-chips, VGA-chip, video switcher and the CPLD have been already soldered up. The other parts (resistors, condensers, wired parts) the user has to assemble by himself.
Currently it is not possible to say when the board will be available. Due to the sale as construction kit, a private sale without a trade intermediary is possible. Currently the CPLD is programmed: Autoconfig is largely implemented, according to Heinrichs programming the memory/IO-statemachine and the monitor switcher is still missing.
For the moment the well-known Picasso driver of the Picasso96 distribution can be used. It is planned to adapt this RTG-system, which currently requires at least a 68020-processor, to the 68000: the planned accelerator board Zeus contains a 50 Mhz 68000 which would be fast enough to supply the graphic board with data.
