Hello,
I have a generic Amiga RTC question. It's more about the Amiga's architecture and how it interacts with RTC units (either plugged in the A1200's clockport or those found on all kinds of accelerator boards).
I purchased an accelerator board without a battery. It had leak-damage and the previous owner removed it. The RTC chip (OKI M6242B) works fine but there is trace-damage between the battery and the RTC chip so the RTC is not powered while the Amiga 1200 is powered off. I hence need to enter the date and time at each power-on and this is annoying.
So far, I can't find anyone that can fix the Circuit board and re-establish contact between the new battery and the board's RTC because no one has the technical information about this accelerator. The battery is a "Panasonic VL1220 HFN 3V 7mAh" which I soldered on myself and which is used often on such boards.
I like Jens his products (I have the AGA Mk3 and it's great) and trust his RTC Module will work fine too. So could I buy the iComp A1200 RTC Module and have it's RTC with onboard CR1220 Battery be used as the only RTC or will it conflict with the accelerators onboard RTC which is, after all, still alive.
Kind regards,
Steve
