What do you mean by 'standard' RGB? I can give you a dozen different and
incompatible RGB standards.
Yes, this monitor has analogue RGB inputs with separate syncs. But the
scan rates are neither US TV rates (which is what the C128 produces) or
VGA. I believe some SVGA cards could drive this given suitable software
(Xfree86 could probably do it if you run linux).

H Frequency : 68.7
US TV is 15.570kHz, VGA is 31.25kHz or thereabouts. V Frequency : 75 Hz
US TV is 60Hz, as is VGA (?)
