        Yes, that's identical to the one inside my box. On the back
of the flash SIMM there's a sticker labled 'LC 475 GM' and 'Apple
Computer (c) 1994'. Do you know if the later machines still retained
the interesting chips such as the Xilinx XC4010-4 and C-Cube MPEG
decoder?

        I've never gotten mine to do anything either. I did see a
site one time that claimed to have actually gotten a display from
theirs though.
