Big Blue Disk / On Disk Monthly used the "least common dominator" method of hardware support - so the were using CGA 4 color graphics into the early 90;s when every one else was using EGA or even VGA.
In the 1980's most PCs only had CGA graphics and beeper sound, which the C64 with its VIC and SID put to shame.
This should look familiar.
