Got this one by PM:
how to start work with CPU 315C-2DP and MMC.
CPU without MMC work good, but with MMC (8MB) - SF LED is lighting RED. I must format MMC, or special start procedure CPU? Help me please. Manual (link) or other.

First thoughts are:
1) Can a 315C-DP really run without its MMC? (I only know the 315-2DP and it can't).
2) Is the MMC a genuine Siemens MMC? They have a special format and as far as I'm aware no one has yet found a way to format a normal MMC so that they can be used in a 300 Series CPU.
3) Can the 315C-DP handle an 8MB MMC. I don't have a catalogue to hand, but the data I have for an older 315-DP says that it can take an EPROM with max. 4 MB.
