  Spectravideo SV-728 and cassette player.    
    The SV-728 was the first fully MSX compatible computer from Spectravideo. 
     I never got the SV-728.  After I sold my SV-328 i moved on to the Atari ST series.

    The SV-728 mainboard is a complete rework compared to the SV-328 and SV-328 MKII.
