This is a very good contribution. And thank you for including the
schematic.
It seems some bits may be missing from the source code.. for example the
function that returns an ID. Do you have this code?

Hello
I just received a mail form Tobias who wrote a DS2423 counter on
Attiny25 AVR Microcontroller. It's a good alternative to original
DS2423 counter which is discontinued and is had to buy. The licensed
under GPL
AFAIK the code is based on owslave(fist implementation for Attiny85)
There is also code for smaller Attiny13 but I did not test it.
The Attiny25 runs well on my poor designed network made of telephone
wire.
This is his page

For building it you need a AVR programmer and of course Attiny25 uC.
No external oscillators needed. If you don't have a AVR programmer You
can make it from an old LPT port of use FT232 usb<->serial converter's
GPIO bitbang.
