Public domain accelerator fro Amiga 1000.

The project is a platfonn board called LUCAS (Little Ugly Cheap Accelerator System) which replaces the 68000 in your Amiga 1000. LUCAS provides greater system perfornance and allows the use of the 68881 math coprocessor as well as an upgrade path to 32-bit wide memory.

The board has a 68020 and 68881 running at 16 MHz, and interface logic (consisting of four PALS, four discretes, a 16 MHz crystal, two SIP resistor paks, and some capacitors) to transpose 68020 cycles to 68000-like cycles. LUCAS also has a connector which will allow you, at a future date, to add 32 bit
wide memory. (I ' ll try to get the fine people at Transactor to publish a memory board for this system in a few months.)

More specs and details can be found int the attached PDF.
