Great to know that you may have even more of those hidden pearls :-) You probably don't know (do you?) if this ever went out of the drawing stage? Like a working prototype for example? BTW - it reminds me like some years ago I put my hands on the XEP-80 (an 80-column add-on for Atari "8-bitters"). This thing plugs into... joystick port and joystick ports are the same in both C64 and Atari series! Since I always wanted 80 columns too, I immediately plugged this into my 64, spent a whole weekend writing a driver that would properly serialize data and handle required communication timings, then I bound it to the KERNAL so that the default screen I/O would go over the XEP, and... yeah.. "gotcha!". Only then, when trying to type-in the first LOAD command on the XEP display, I realized that no matter how hard I try, I shall never be able to use the 80-cols display AND the keyboard at the same time. I don't ever recall feeling as stupid as I felt that Sunday evening... ;-) -- SD! Message was sent through the cbm-hackers mailing listReceived on 2013-08-18 11:03:47
