This entire respose actually belongs to a PBS employee without net-access. It gives comments and worries about the Amiga 2000 from the standpoint of needs in production work. She currently uses a 1000 with 2 megs external ram and a extra DMA comtroller for data swapping. The station is considering several 2000's: --------strong needs/wishes------ Digital RGB on the video slot connector with 4 bits/gun and an extra 4 pins/gun of nothing for future expansion. If the extra half meg of memory is to be slow fast memory then a jumper or kludge to disable it so some true fast memory can be added. With the Amiga 1000 we are already using we need fast memory to keep the frame rate up when using high-res overscan interlace. It is unacceptable for any of the slow fast memory to get allocated. [Editorial: THIS is what I was talking about on the 500/They specify MEMF_FAST and expect to get it -Bryce] We run out of chip memory first... We run out of colors second... (though HAM with twice the bandwidth would probably about settle it) Better DESCRIPTIONS of the overscan support, particularly in relation to intuition and hot spots on gadgets. ----------other items---------- Tiny jumper on PCB to place +5 volts on the parallel port. If you want to get fancy you could spend as much as two PCB holes implementing this. I LOVE the modular (RJ-11) jack on the 1000's keyboard. First thing I did was go to Radio Shack and get a 25 footer. Too bad it's gone... MORE DISK SPACE! I heard sony has a 2 meg drive out, also one that runs at 600 RMP. Yes, I will pay more... must read/write older dis of a w inver
