View Full Version : EGA mono graphics mode

May 13th, 2010, 09:54 AM
I have gotten the IBM EGA card I jsut aquired, and I have now run the advanced diagnostics v2.25 on it to see if it's malfunctioning.

One problem is that on some of the tests, I don't know how it actually is supposed to look like. This is a problem, since it didn't look quite usual on the 640x350 test. What I find odd is that the rightmost square is flashing, but not on the part overlapping the middle square. I am sure I have set all the jumpers corrctly, and I do use a real 5151 with it.

Is anybody able to verify if this is correct behavour for this graphics mode?
