[Boatanchors] Diagram for Squeeze Key dated 25-4-76, 8 ICs & using ext PS

[Henry Meils]

Hi
I bought an unusual model Squeeze Key about ½ the standard size, i.e. doesn't have the usual built in PS. It has eight SN74 ... ICs, a 5V voltage regulator and two ON113 transistors. Does anyone have a circuit diagram so I can get it work (the previous owner made some mods).

Thanks in advance.
