another 1.2V DTL variant

trivial random inverter osc. test

2N2222 OUTP , a composite "diode" from 2N2907 1N4148 -- NAND logic
designed for up to 1...2 MHz operation at 1.2V supply
at lesser speeds it can work starting from 620mV supply ...
... which has much no point in practice coz below ??? say 850mV (good battery types) usually 1.13V (most battery types) the terminal voltage drops fast (some minutes even seconds -- tough -- during that some startup circuits can be driven) and deceases -- so below 1.13V (unloaded) terminal voltage the 1.2V battery is basically empty

counters compared XC , JK , Pulse , T
