Super MVS convertor II plus

Uses an Actel ProASIC V3 FPGA on each board. They're AES-decryption capable for SPI flash and fusemap update, and generally highly temper-proof.

Has two SPI ports for FPGA updates and one unrouted mini-USB port labelled "BIOS".

Boards dated May 2011. Seems to suffer of very bad soldering job on connectors.
