Hi Allison,
I've never used the 6845 CRTC but over the years
I've heard the Hitachi
part is a better version than the older Motorola
one. Lacking a datasheet
for Hitachi what is the differnce?
Take a look at:
http://andercheran.aiind.upv.es/~amstrad/docs/crtcnew.html
It appears that the Moto part it a 'Type 2' and the
Hitachi part is a 'Type 0'. The differences between
each type (as well as others) appear to be detailed in
the 'CRTC Differences' section of this web site.
