So you have a 6300 or M24 that you've used the Eagle 5151 clone with?
I'm surprised that it worked.
The 6300 outputs a 640x400 display, so the frequencies are actually
closer to VGA than monochrome. (about 30KHz horizontal/60Hz vertical,
if memory serves). IBM hi-res CGA mode was emulated by doubling each
horizontal line.
I've used a 6300 with an Acer AL1916W display with very nice results.
It's not monochrome, but it's very sharp.
You can, using jumpers (and removing a PAL on some versions) disable the
inboard video and add an EGA or VGA card. I'm not aware that the BIOS
has any support for a standard MDA card. The 6300 is odd in that the
video card also serves to couple the motherboard to the bus converter
board, so it can't simply be removed.
I think it'd probably toast a 5151 display.
