I don't think this is the place to discuss that
Sure it is, the C128 is the Amiga's uncle. Repect your elders! ;-) But seriously, Wayne and co here are open minded.
Now I'm not a real electronics guru but you basically have two bits per channel. So with 2 resitors (per channel) you could build yourself a DAC and feed that signal to the scandoubler
Resistors :-? I'll look into this, probably ask on c.s.c. At this time there is no
good converter for the 128 RBGi.
