And I'm in as co-author of the sequel "How to Live With a Japanese Wife and Survive" :-DD

I thought Japanese wimens were submissive and meek? No?

LOL the one I’m friends with is a deeply cynical vicious sick and twisted individual. Conversion diverged into anal polyps and how good laughing gas is last time. Just how I like them :-DD

You like anal polyps?!
Over time laughing gas knackers your bones and B12; that's why dentists don't use it any more. Ambulance crews can; when they gave it to me, I was transported back to childhood!

I haven't come across Udemy before. A quick glance reminds me of the "for Dummies" books.
I believe that traditionally Japanese wives have sole and complete authority over the family finances.

Gosh really? We'd never noticed... 😇

Nope.
4000B CMOS is specified down to 3V supply. Which means that both the P & N device thresholds must be less than that. So at 6V supply or thereabouts, both can be on at the same time, when the input to a gate is at around mid rail. This happens at pin 11 twice every cycle of the oscillator. With fresh batteries, this takes a significant and unnecessary gulp of charge from the supply. D1 drops just enough voltage to significantly reduce this, while, unlike a regulator, dissipating no standby power.
Note there is no capacitor at U1 pin 16. If you put one here, it will happily supply the unwanted gulp, and charge itself back up during the rest of the cycle. Bad capacitor! But 4000 CMOS is slow enough not to absolutely require decoupling directly at the chip.
As I said, 4000 CMOS is cool!

Neat trick :)

I love you long time baby!

Is the firmware the only thing you want out?
As soon as I have a GPIB solution (isn't that the way to do it, or is it programmer on proms? ) I'll do what I can.

GPIB is easiest (I.E. the way do it, as I know how to do it this way) If you can get the NVRAM out using the instructions (I can help you with exact commands if needed), that would be good too, but the main one is the firmware. The NVRAM holds the options mostly which can be poked at and unlocked via GPIB later with a few simple commands anyway.

This is a thing..... |O :-DD
I have my own side funds for TEA gear besides the 'official' book keeping. :-DD
