Will you have another batch of the cartridge adapter? i'd like to install mine externally. (i'm more or less back to atari stuff and am currently working on modding my gotek btw).
I don't think so no.. was a thread about it, wasn't enough interest to invest in making them. I only made 3 prototypes, I think RJ was the only taker.

I think the PCB ended up a expensive 4 layer to route how I wanted. The original was 2 layers, but I also had the problem of stocking the same RTC twice, so I was trying to reduce some costs, but it made the PCB expensive instead, so didn't really help. I wanted to keep a solid gnd and 5V layer to help stop voltage drops across the board to other "in series" carts as well. The RTC module itself I discontinued already, again just wasn't any interest in it.

Incidentally, I do plan to fit the Falcon RTC modules to the STF remake at some point.

Ok, so I have 3 complete modern RTC cartridges (They are uncased), If you want one of them, drop me a PM, and we can agree a price. They were quite expensive to bulid, the RTC chips were £10 each, so total cost to build each one was upwards of £30-£40 for me including the PCBs, however, I'm sure we could agree a price that is good for us both, and I will cover postage costs.

Well i wanted only the cartridge pcb, since i already have a completed rtc. but since i have two ataris i'll think it over.
If i take too long to reply, sorry my cat is sleeping on my laps.

See my previous answer, i already have a completed exxos rtc (and since i participated in the development, i want to use it). I only wanted the pcb for the cartridge conversion of this rtc, for an easyier installation and the possibility to use it on two different st (not at the same time of course) instead of soldering it inside.
Besides the exxos rtc is a forget me clock 2 reworked with a year 2k debugged ic.
