Can't set tod clock =================== Well, I can. The SGI machines have one specialty: they do not use normal batteries (like the CR2032) to keep the time (and even to keep some other data). They use Tadiran or Dallas chips that include the batteries. My Indigo system (it's a re-branded as Siemens RW3200) came with a hack - the original Tadiran battery was replaced by soldered CR2032. It was not a bad thing but the battery was already dead. I got the original replacement one before I have found that the system was modified in this way. But I decided to solder in a socket for the battery to allow easier battery replacement (the original one can survive 15 years but the CR2032 just a few years). After some attempts (I was too scared about possible damage of the computer) I decided to just remove the remains of soldering a to put the original battery to the proper place (it was manufactured in 2016 so it's possibly can be used to at least 2026). And I no longer see the message in the heading of this text ;-) It have made the Indigo a bit better. The last change should be an installation of a floppy drive (it I will be able to find one - it must be a SCSI floppy).
