If you look at the zeroes you can clearly see that the first image is of a different font than the second one. Over the years we standardized on the System PC font which may be in the second image. However the second image could also be TERMINAL which, with respect to size, is a slight improvement over System PC. I am about to drop the System PC default in 4.3 in favor of LUCIDA CONSOLE, which may be the font in the first image.
I recently upgraded several of my customers by placing a FONT LUCIDA CONSOLE statement in their config.sys file.
