I did some measurements and ascertained that the levels used are 0v and 5 v
(4.59v, actually), so this will trigger my synths. As to how it will handle
overvoltage inputs.. good question: I need to look at my TTL texts. There
is no buffering anywhere in the system; this is all raw ICs, with some
additional support circuitry.

Zeners on the inputs might solve that problem...
