Well, people actually sold 80 col cartridge add-ons back in the days. (More or less the same hardware were also sold for the VIC 20, those could be switched between 40 and 80 col). The general use case for the dual video output for the C128 seems to be software development. Coding on the 80 col display, and viewing the result on the 40 col dispaly. The use case for this software that does 40 col is imho even more limited as it can only do text mode, no hires, no sprites and most likely no user defined char set, and it requires pressing a key combination for manual update for any software that writes directly to screen ram rather than through the kernal. > I wonder what was special about the software he needed to run that it > would work in a c64 where the rom had been copied to ram and the text > screen was remapped, but wouldn't work in c128 mode. Probably just that it was written for usage on the C64 in general? > The loss of 1764 basic bytes is weird. -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
