RTC chip replacement

[robin-fo]

Hi everybody

I‘m looking for a replacement of my SE/30‘s battery-bombed RTC chip. I know of the ATTiny85 source code, but my machine is not accepting it and refuses to boot from Floppy or HD.
Has anybody experience with this replacement chip or does somebody have spares?

Many thanks,
Robin

Does it really work?

Used it on that and had absolutely no issues.

So PRAM, Date, Time and incrementing seconds worked?

For me yes but this was on a 512k the pinouts seem to be the same so I don’t see why it wouldn’t,
