I had the Vic-20 with the Datasette drive (Tape Recorder) as well as the 64C (Which was a more streamilined and updated version of the C-64) and I ran both of the on a 13" Magnavox B&W TV.
I still have the 300bps modem as well as an Epyx Fast Load Cartridge (Remember them? They made Summer & Winter games) that supposedly made your 1541 load games quicker. I still have it in a box here somewhere. I should find it and take a pic
Those were the days when my days were filled with BBS chat and my evening's were filled with Infocom's Zork!
