ECS upgrade consists of two chips,AGNUS& DENISE,PAULA & GARY are
uninvolved. ECS AGNUS (CSG PN 8372) is bonded out for 1MB chip RAM,can
be switched from PAL to NTSC in both h/w and s/w, and has new programmable
video registers. ECS Denise (this one's my puppy) supports 35nSec
pixels, new programmable video registers, and all kind of new genlock
goodies put in at Dale Luck's request. Basically this chip set was
created to support productivity mode, but as you can see some other
stuff came along for the ride. Hope this dispels some confusion.
