My Sun Ultra 10, or rather both of my Sun Ultra 10s, have an annoyingly common problem: the battery in the NVRAM module is dead. And thanks to Sun storing the machine ID code and the MAC address in the NVRAM, Solaris will not boot properly unless you manually program the NVRAM each cold boot. And if the system loses power for a split-second? Do over!
Which is why I have bought a repair board from The Glitch Works - it will let me repair the original module with a replaceable coin cell battery. You could do a battery mod to the 48T59, but the contacts are more difficult to get to, so this repair board will probably make the job easier.
Will I successfully repair the NVRAM module? Will I regret the tools I have at my disposal? Will I have time to do anything else? You'll have to watch to find out!

YouTube started having ingest issues while I was doing the Wheel of Regrets! segment. This VOD resumes where Wheel of Regrets! left off in the first attempt: https://youtube.com/live/e2C_R8njKkQ
At least I cant blame my USB microphone this time around...

Adam sent me an Apple ][+ that needs repairs, and COMPUTER is suffering from bad 74LS-series chips. Can I fix both computers using eBay (the place where I buy things I later regret)? Maybe. But the more important question is, Will there be regrets along the way?
Will COMPUTER say COMPUTER again? Will the Apple ][+ say APPLE ][ again? Will all the parts even arrive in time for this stream? Youll have to watch to find out!
