@stirz @Wintermute_BBS I believe that black color is coming from the ZX Spectrum because commodore TED machines (plus/4, 16) was intended to compete with ZX Spectrum machine :)
@stirz @Wintermute_BBS Yes, more powerful BASIC and they do have a dedicated rs232 chip and that means higher speeds but they have locked GPIO pins on the user port for a specific application; if not for that, these would be a great retro embedded platform from the '80s :)
@josipretrobits @Wintermute_BBS oh, I did not know that! Cool feature!
@josipretrobits @Wintermute_BBS Valid point. Commodore management was not aware of the inportance of compatibility, as Brian Bagnall has pointed out. That let the 264 series fail.
I personally had embraced a compatible machine with more than 16 colours (like the C64), capable to use a fast floppy like the 1551, having a sophisticated BASIC and nice cursor keys (like the Plus/4)
