View Full Version : Xerox 820 II ready to run!

Hello Everyone!

I've replaced the mains caps from my Xerox 820 II.
The left power is from the floppy drives and the right one is from the CPU.

10360 10361

I've seen these burn many times. They are 275VAC but our mains voltage
is raised from 220 to 240 over the years. And these caps ages. Even when
you don't use them they get some cracks and moisture comes in.
The used materials are hygroscopic. I'd check them using a megger and they
had all a big leakage current.

I've made a short movie on youtube. I hope you like it. There are some
games on the disk which I show.


Regards, Roland

Cool movie... also like the one of the Cypher stream with the IBM XT (wel misschien wat meer inzoomen op het scherm?) ;-)

Thank you! Maybe I should buy an other camera.
The picture quality is much better than the movie quality.
That is why I put in some pictures too.

The IBM is a nice machine also. I'd never seen a second cipher again.
