No, ECS is a superset of the original chip set - anything they can do >we can do(unless Victor and I broke something and nobody told us about >it :-) !!!). Basically ECS involves three things: 1.) programmability of timing registers that used to be hard-wired(horizontal total,start and end of blanking,etc.) 2.) creation of a SHRES pixel resolution(35nS) 3.) additional genlock support(border transparency control,color table and bitplane transparency,etc.) Using 2.0 preferences you can set horizontal scan rate to 15 or 31 KHz. For applications, horizontal and frame frequency are programmable over a large range of values. QUESTION: I'll try and make this as simple as possible:- SETUP = Amiga 2000 + ECS + WB2.0 I definately want to get a VGA (not Multisync) monitor BUT WILL I BE ABLE TO USE THE MONITOR WITH ALL SCREEN MODES? eg. Boot up in normal 640x256 or 320x256 modes. Not just Productivity all the time. (Note that the VGA Monitor has a constant scan rate of 31kHz. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Amiga : /// | Matthew Crowd There /// | Research Assistant is no \\\/// | James Cook University substitute \XX/ | email : =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
