@furrtek Just got around to hooking up the o'scope to the Dolby DA20.

Yellow trace is on pin 4 (TTC) of the Reader 1 DSUB25, and is a pulse at 50 KHz.

Blue trace is on pin 7 (TSC), and is around 14 MHz. Actually closer to 13.7 MHz.
I counted 256 TSC clock cycles between each TTC pulse.

I've not hooked up the CCD yet, as I haven't decided on which cable(s) to scavenge for it. lol

And still no way to spool the reel. I looked for some 35mm sprockets/rollers/reels again on eBay last night, but not much luck.
@TheMogMiner From left-to-right on the DA20 chassis, these are the first two boards.

The ADC board for the CCD, and the first of two DSP56K1 boards.

(second DSP56K1 not shown in this thread.)
The main DSP56K2 control board, and the Zoran AC3 dec.

(sorry for any rotated images, my S7 hates me.)
The 6-channel opamp board, and the analog out board.

(the analog out board also has some motor detect stuff for the projector, and CP interface.)
You can follow @AshEvans81.
