HxC on a CX-5M (MSX-1)

Post by solderhead »

I recently "inherited" 3 - Yamaha CX-5MU Music Computers. Has anyone tried to use an HxC emulator on these units ?

Unfortunately, no. It's got a "game cartridge" slot in the top and a 50 pin "expansion slot" in the rear. The
Yamaha FD-03 Floppy Drive has a cartridge which plugs into a " CA-01 Single Cartridge Adapter", which is
more or less just a gender changer. The floppy disk cartridge has logic in it which takes the raw buss signals
from the expansion slot, combines them however it needs them and funnels them down to a round 14 pin cable
to the floppy drive itself !! ( Can't make anything EASY can they ??!!) Just wondering if someone - ANYONE -
took the time to figure out the voodoo that made this work / adaptable to a "standard" floppy format. Thanks.

Open this cartridge, take a picture and post it here.

14 pin is enough for a Shugart interface :)
It's what you get for Atari ST external drives or the french Thomson TO ones. They use the same connector but different wirings, so be careful :)

You should replace the floppy in the FD3 by the hxC. I can try with a similar configuration but my floppy unit is a canon that was sold with a V20.

I'd love to get the HXC2001 to work with my Yamaha CX5M II/128 music computer (MSX 1). The standard floppy disk drive for this computer was the Yamaha FD-03 or FD-05, using the Yamaha FD-051 interface cable.

I've uploaded a copy of the Yamaha Service Manual for the FD-05 and FD-051 to my website here: FD-05 / FD-051 Service Manual. It includes circuit diagrams and connector pin-outs etc. Perhaps this provides the required information.

The emulator is probably already compatible with this interface.
You can connect the HxC directly to the FDC cardridge.
