Canon V-30F
This page was last modified 21:56, 13 March 2021 by Mars2000you. Based on work by Msxholder and Rderooy and others.



The V-30F comes with a separate keyboard and 1 disk drive by default (there's a location planned for the addition of a second disk drive). It's the last computer released by Canon for the MSX system and the only one with a built-in floppy drive.

The keyboard looks like a PC keyboard and there's an eject button for the first cartridge slot. This computer was aimed at the Japanese market.

For the photography fans, this machine is recommended to be used with an innovative digital Interface Unit DMB between the computer and the Canon T90 Single-lens reflex (SLR) camera. DMB-90 means Data Memory Back 90.
