I was quite puzzled by the presence of the "half-bright" mode in the Amiga. If one extra bit-plane is used to get the extra shades, why not just use it to get twice as many colors as present in lo-res mode? Surely this will be lot more flexible than the half-bright mode..... Anyone care to comment on this? -- UUCP: {ihnp4,seismo,ucbvax,dcdwest}!sdcsvax!nosc!uhccux!yuan ARPA: uhccux!yuan@nosc.ARPA INTERNET: yuan@UHCC.HAWAII.EDU AT&T: (808) 395-1732 "I'm an Amigoid, she's an Amigoid, they're Amigoids, - Yuan Chang - Wouldn't _y_o_u like to be an Amigoid too?"

Because you would have to double the number of color registers and their associated logic, and presumably this was too expensive in terms of custom chip real estate. -- ---------------- "... if the church put in half the time on covetousness Mike Farren that it does on lust, this would be a better world ..." hoptoad!farren Garrison Keillor, "Lake Wobegon Days"

According to my sources, half-brite was added as a way to extend the number of colors without making changes too large at the point in time the feature was added. Using the extra bit-plane in the straight forward way would have required doubling the size of the color lookup table which would have caused serious chip layout problems and would have used up all or allmost all the available chip register addresses. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)

I think half-bright mode was added as an afterthought. Otherwise they would simply have had 64 color registers. -Matt

Just for information sake. In the latest issue of Amazing Computing, there is going to be availble, an Amiga genlock which makes use of S connector for use with S-VHS and ED Beta. It's called GEN/ONE. Cost is $895.00 retail. Availability is June 88.

Whats the developement on the new video standard for the Amiga? Are they going be supporting the VGA and EGA standard? On Multitasking: I am a hardcore PC fan. Although I hate to admit it, the primary reason for me being interested in the Amiga is because of its PC compatibility. The other reason is its Multi-tasking abilities. I can understand PC users being obstinant because they have a machine with such features. I would like to think I am an exception since before I was considering buying the amiga I was going to purchase an Inboard 386 for my PC. (this is still in effect except that I am going to put the board in the Amiga :-) Sri

Let's wait a year and get HDTV support. That would be much more in line with the Amiga philosophy. >I am a hardcore PC fan. Nobody's perfect.

I doubt that the Amiga itself will ever use either of those formats because they (esp. EGA) represent a step backwards in technology. What is more likely is that EGA and maybe VGA will be supported on some future bridgecard.
