I have a 2640 which I recently refurbished the screen on and it runs happily and then a 2645 that still needs treatment for the screen rot. Is the binaries for pong and space invaders downloadable somewhere? I searched the usual places, but haven't found anything. It would be interesting to test this binary download mode. > > > Christian > /Mattis
