[R-1051] 100 cps Synthesizer module

[Francesco Ledda]

Hi, 

I have two versions of the 100Hz synthesizer here.  One has RTL logic and
the other TTL dips.  I only have the schematic of the RTL one, and I never
seen a schematic of the other one.  I am very curios to find out when the
TTL version was introduced....

BR,

Hi Dennis et al,
	I haven't been following this thread very closely, but the "thanks
Al" 
caught my eye.  The real thanks are to Dennis.  I'm not sure how long ago we
put that big file up there, but I hope it's useful.
	While looking for it in my present hard drive (with no luck) I found
I do have 6 .jpg's of the manual pages for the R1051D 100 cps  synth.  If
you think that'd be helpful, I can get them up on that same webpage pretty
quickly.
