I recently bought a version of this card from and got it installed in the 0.5MB chip + 1.5MB slow configuration. (Thanks Jope for helping debug my JP2/JP7A brainfart!) Unfortunately neither the OS or the Amiga Test Kit find the RTC on board. SetClock RESET doesn't do the trick. I've measured that the Epson RTC-72421A chip does get 3V from the battery (pins 9 and 18) but other than that I'm not sure where to look at. Any ideas what might cause the RTC not to be found?

I did have the card installed for a moment with an incorrect JP2/JP7A setup. May this have killed the RTC on the card? During the installation process the TOD part of my CIAA also died. Not sure if it's related or not.
