#More Colors Wanted

I have one major reservation about the new Amiga 3000. It seems that Commodore is moving in the opposite direction from IBM and Apple in terms of number of displayable colors. This bothers me because I would have eventually liked to have seen a Bridgeboard with software capable of operation in an emulated VGA mode. In addition, the "Super Hi-Res" modes that the 3000 brings are good for monchrome desktop publishing; however, for CAD and painting applications, more colors would be better (the special video modes supposedly have only 4 colors or 2 bit planes). I have heard of some special display boards but I didn't see anything about them at the World of Amiga. Also, I would want the display capability to be standard for both software compatability reasons and cost.

I'm a bit confused by this message. How do you feel that CBM is moving in the opposite direction from IBM and Apple in terms of displayable colors? Did they remove HAM without telling anyone? To the best of my knowledge, the 3000 can still display 4096 colors right out of the box. Now the Bridgeboard is a whole different ballgame. It is an independent option that has little to do with using a 2000 or 3000 as it's host. In any event, VGA is hardware as well as software, so I rather doubt it would be cost effective for CBM to produce a VGA capable bridgeboard for the Amiga at this time. (At least that would be the case for this customer. As long as the Amiga has PC slots equal to or in excess of the number of Amiga slots on a PC, I'd be happy with it.) I can't really comment on the special new modes. If I had to guess, I would imagine they were done that way as a trade-off between having the higher resolution available or having more color in an environment with a cost effective amount of RAM. I would also imagine that some enterprising third party developers will investigate the marketability of an add-on to increase the colors available in those modes once the 3000/2.0 chipset comes into general availability. (It may well be that the cost of such an add-on vs. the probable market would cause the idea to be dropped though.)

Well, the Amiga can already display more colours than a Mac or MsDos machine. When they get a HAM-alike mode, we can talk about number of colours again. CBM is not moving in the opposite direction, but are, for now, staying with the same number of colours _in the box_.

See my response to #101004. I know the operating system was designed to use more than 4-5 bit planes. I had hoped that they would expand that area first.

Sorry we couldn't be at Worl Of Amiga, but we were at a much bigger show (The Dayton HamVENTION) showing our new 262,144 color adaptor for all Amigas. If you can make the Chicago AmiExpo, we'll be there (even tho the DevCon overlaps with it). Compatability: It uses your current monitor, the Blitter and the CPU can get at the memory, you can open windows, use gadgets and so on under the current OS so that developers can write applications for it using most of the current ROM toolset. Installation is trivial (plugs in line with your monitor, no opening the case) and it will work with _any_ Amiga. Our multi-color solution is extremely fast, works perfectly with existing IFF viewers, amd is inexpensive ($300.00 or thereabouts). Hope that encourages you somewhat.

Ben, I've been hearing alot about your HAM-E board, and it sounds great. I have a question though. Are there any problems with animation? I had heard that while the board is active, the Amiga is busy displaying a 640x whatever 4 bit-plane display, and this chews up a lot of cycles (especially with overscan). Can you comment on this? I'm sure the excellent quality of the images would more than compensate for any speed loss, but I was just wondering if a fast Amiga (2500 or up) would be required for smooth animation.

Good questions. 4 bitplanes in hires it is indeed, and if you need to rewrite the entire screen, it can take longer than you would want to even blitting in the bitplanes. Most animation does NOT have changes in every region of the screen, however, so you can have quite a nice looking display with some minimal care in selecting what updates and changes and so on. I would _always_ suggest the blitter as the data mover, and in that case the speed of the CPU has little (if anything) to do with the animation speed. When doing single frame stuff the question doesn't arise, of course.

Steven, various Commodorians have hinted at the fact that there are things in the works. Unless you become a certified developer, just like me you won't know till its out.
