The Modulo 61 M/A has been designed using a custom multilayer board, semicustom IC drivers, a light plate, and alignment assembly. A light plate and an accompanying alignment assembly and procedure have been designed to form in excess of 500 optical interconnections at once to interconnect the M/A. A discrete 3 x 3 LUT will perform at 100 MHz; the Modulo 61 M/A will run at between 100 and 200 MHz.
