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. 
That helps, Thanks now I can go to the moto data and feel 
comfortable.

Allison
