[R-1051] 100 cps Synthesizer module

[paul swed]

Boy no expert.
The alcohol is acting as a cooling agent. (Never thought of using it that
way before. Good trick.) The ICs should be RTL logic for that time frame.
That can be confirmed by the voltage feeding them. 3.6 V for RTL.
If its 5 V they are most likely DTL or TTL. I know there is little info on
the net for RTL and even DTL. However more modern logic families could
indeed replace those chips if worse came to worse.
I will not have time to look atthe logic for at least a week. Travel.
Good luck
