Unknown 68k turboboard with 68020 and 68882 !!!

"Hcmos 32-bit Virtual Memory Microprocessor - Atmel Corporation
The TS68020 is the first full 32-bit implementation of the TS68000 family of micropro- cessors. Using HCMOS technology, the TS68020 is implemented with 32-bit Registers and data paths, 32-bit addresses, a rich instruction set, and versatile addressing modes. By ATMEL Corporation"

Sounds very much like just a licensed 68020 clone, probably no connection to the board in question.

Does the board's shape look A500 optimized? Possibly it's intended for another system (Atari, Mac).

It might just be a very simplistic design, running the '020 in 16 bit mode synchronously, reducing glue logic to a minimum. Only speed up you'd get is from instruction cache and FPU.
