I don’t have all details about the power supply, you have mention to use 9V, but that’s a battery 6LR61 type?
Initially ‘the project’ was based on CMOS chips and they work with a broader range of power supply voltages. While TTL ICs all require a power supply voltage of 5V, CMOS works with a wider range of power supply voltage – usually anywhere from 3 to 15V.
So we have planned 74HC47 = CMOS power supply 3 to 15V.
We have changed for 74LS47 and 74LS193 (Low-power Schottky TTL) so we need now also a 5V power supply. This mean to add an extra circuit (a Positive Voltage Regulator) to obtain 5V from 9V.
In order to use the 74LS193 (instead of a 74LS192), we need also additional gates, so it’s not so simple, better to buy directly the ‘192’ series. Preferable to buy CD40192 presettable BCD Up/Down Counter or TTL series 74LS192.
