All, Can't seem to find any information, other than a few magazine ads, on a S100 clock board I've got. It's marked: 1980 IDS International Data Systems, INC 88-SPM Clock Module V01 Looks like it's another TTL clock, I can't pick out any RTC chips or repurposed alarm clocks. Schematic, manual, programs you know interact with one of these, et c. would be super helpful! Thanks, Jonathan
