As if trying to use a 74LS14 on a 3.3v circuit was not bad enough
I did not even initially have any power or ground of any sort on the IC… (may have been a blessing )
at least I don’t have to cut an incorrect 5V line, just tap a 3.3…
This must have been a Friday afternoon job, bit superflous anyway as it’s only used if not using the MIDI tell-tale circuit.
