Williams Hardware, Switchers and CMOS

Friday, August 16th, 2019

So this keeps coming up a few times a year, almost like people completely forget about Google no every now and then.

Someone has a Williams 6809 hardware game like Defender, Stargate, Joust, etc.  They install a switcher instead of repairing the existing linear supply (people have their reasons), and everything works great, except for the fact that they occasionally get CMOS corruption and lose things like settings, bookeeping, and scores.

Is something wrong with the switcher?  No, something is just wrong with the CPU.
