An extra-large picture for the MDFS motherboard! I hope it didn't take you as long to download it as it took me to upload it!

The MDFS is a Z80-based circuit, with an Econet interface in the bottom left-hand corner which is not built around the 68B54 ADLC chip. On-board is the system ROM version 1.05 which is the most recent version and a battery to store the configuration settings and time. The clock chip is a 146818, just like in the Master series.
