I would like to get the RTC going in my Model III which came as a feature on the aftermarket Holmes FDC DX-3D board it has fitted. I renewed the on-board battery, but first relocated it to make future renewals easy. I can't find any docs about this FDC + RTC, so have tried Newclock-80 port addresses. No dice, though I do see seconds I believe ticking away on port 231. However only the "ones" (0-9), no "tens", minutes, hours or date is apparent. I would like to use this RTC with MultiDos.
Anybody have one that works &/or docs/programs for it?
Many thanks
Philip
