Re: 2220 POST displays a large X on the screen

 

I would have hoped for something like the Sad Mac diagnostic screen
made up of a pair of Xs and a caret. If I ever design a DSO or
anything which uses a vector display, that is what I am going to use.

The ROM versions are:

and
09110 2200 160-3976-13

The X certainly acts as an "I'm not well" indicator, even if not intended. The image of a capacitor with an X though it would be even better. I'm sure you are right about the glitches on the 5V rail.

I'm intrigued at the thought of adding CRT readout as in the 2221. I wonder if it's just a case of different ROMs, which of course are made from unobtanium, so just fanciful thinking!
