Thanks, Tobias, that must be it :)

Do you also happen to know: Does the battery backed clock on the Minerva MkII make the one on the SGC redundant? 'Cause I see Ive removed the one on the SGC.

this looks to me like a Minerva MkII - The version that didn't just replace the ROM, but added I²C, a BOOT device that could hold a small amount of SuperBASIC to divert the BOOT process to the network and a working battery back-up for the real-time clock:

No need, Minerva v1.97 is available for download.

The I²C extensions to Minerva are loaded in at boot time or LRESPRed.

The Clock in the Minerva MKII can work with the SuperGold Card, I removed the Minerva Battery, only because the Supergold Card battery is much neated. BUt in the light of no Super/Gold Card batteries, I went back to the Minerva MKII Battery.

I received a lot of battery replacements PCBs this week.
So there are new battery replacements coming soon.

Paul,

a word of thanks: your battery replacement PCB is extremely nice, I'm a very happy user of it!

Kind regards,
Petri

What is missing on minerva mkII is the PAL/GAL equations. If someone can get the full set (the available set is missing the i2c stuff), then I think Dave had a load of mkII PCBs made.
