A few features were only found on TED and, as far as I know, never used again in any other Commodore video controller: - switching between normal and double CPU clock depending on whether the video circuit needs to fetch video data or not (much better IMHO than the all or nothing approach in the C128) - hardware text cursor - hardware blinking - hardware reverse characters - adjustable luma levels for each color - writable row and column counters in video circuit. - full 64KB access for the video circuit so you were able to place the character ROM and video RAM anywhere you wanted, including under the ROM. - Same chip for PAL and NTSC, selectable by software, allowing for easy overclocking if you have a PAL 264. The last one sorta came back with the 8372 in the Amiga, without the overclocking part though. Gerrit Message was sent through the cbm-hackers mailing listReceived on 2012-04-19 18:00:05
