I have no clue how I missed this group/thread other than I may have been too excited to do a thing before needed to know if I had to do a thing.

I got one of these with a FT-301D and FV-301D and since I do a lot of work on old embedded/arcade stuff...I work with parallel EPROMS all the time. So I sat down a few hours ago with the schematic and basically reverse engineered that the data was timecode with sequential addressing. Actually...the minute I saw the 74151 and 7493s I started guessing when they said "time-code" in the US manual they literally meant time-code.

Anyway...the only thing I hadn't worked out was the bit length of various things, which now that I've got? the Japanese manual with that information I'll have zero guesswork when doing a mockup. I might try to write a python application that will generate an image file that'll work with image burners. I'm also considering if my clock chip doesn't work just replacing everything with an Arduino and RTC module.
