I believe 1/2-inch Dictaphone was 10/20 tracks and 1-inch was 20/40
tracks, but I've never put together a comprehensive listing of logging
track formats. Each manufacturer seemed to have a different track
configuration (and steps). I started at one point and maybe I should
research it sometime.
My logging machines went to Chris Brown a couple of years ago and I was
glad to get rid of them. I did save some of the heads if you're up to
mounting them. I'm pretty certain I have a 20-track head assembly. The
courtroom playback machines were a 40-channel mixer and one output. I
did some preliminary work to provide 40 outputs and gave that to Chris.
I don't know if he's implemented that.
You do know that one 10.5-inch reel of logging tape (typically 3600
feet) holds about 25 hours of material...and with 20 tracks, that's 500
hours of audio!
Speed was almost universally 15/32 in/s.
The timecode can be read with a reader if you have one, but I've had
success reading IRIG timecodes in the DAW by actually reading bits.
I've never seen a bitmap for the Dictaphone time code.
