OK, down the rathole again with a CSA8000b...
4 to 5 yrs ago, I bought a CSA8000B for $150. The person was local, college student thought it was a scope, even delivered it. It powered on but had the Dallas eeprom (if that's the right term) issue so it didn't boot. The instructions on eevblog are good and I was able to bring it up but you need the dallas eeproms to hold the boot instructions or its a hassle getting it to run. So I bought the dallas modules for both the PC and PPC boards, carefully soldered them on, had to go back and touch them up, etc. Not a lot of fun as one is up next to a card connector and yes, I had some melted plastic by the time it was done. I had programmed the eeproms and the unit booted correctly. I have a 20Ghz electrical module and that came up. But when I measured the calibrator, I remember the voltage was low by a factor of 10 maybe. So after playing around with settings I powered down, reseated the cards and of course, my brand new eeprom from asia hadn't held the config. There isn't much in there, just a couple instructions on where to find the PPC boot code! But do you think it could keep it just once!! Nope.
And this really po'ed me! While typing this the guy who agreed to sell it to me for the asking price just said he had a higher offer, $50 more. That's a little lame, don't you think? Told him to keep it. This is a company too, not just a person on the web. I mean is that any way to do business?
