The HC-F303 is a single sided 360kB 3.5" floppy disk drive with interface adapter HC-FC303, released by JVC/Victor. It supports up to two drives.

It is Identical to the Philips VY-0010 and Sakhr AFD-01, even the ROMs can be swapped. It is possible to upgrade the ROM to support double sided (720kB) media, but this also requires the actual drive to be replaced.

This device was released under the Victor brand in Japan and under the JVC brand in Europe.

In Japan the interface and drive were sold separately, such that you could purchase a second drive. In Europe it was only offered as a set.

A second disk drive was not offered separately in Europe, although you could use the Philips VY-0011 as it is the same drive.

The interface includes a ROM with version 1 of the Disk BASIC instructions.

The JVC/Victor disk rom has a few additional calls:

  • _getver shows this on screen:
     MSX disk basic system      
     1985/06/20 version.        
  presented by JVC              
             (MAEBASHI) Japan.  
  • _VICTOR displays this:
     MSX disk basic system      
         presented by           
  Victor company of Japan, LTD. 

The ROM also contains the following text:

This driver soft is made for 3.5 inches floppy disk drive with side detector.  
Formatter automatically selects side.
