There was a
recent eBay auction where a guy was selling a USB to
Serial mouse converter with his S-550. He also claimed it would work
on an S-760.
Except that plugging in a serial mouse was what fried my S550 mouse
port in the first place. The S550 plug looks like a normal serial
port but apparently the connections are different.
Also the same port style as Atari ST, Amiga, Commodore 64, Atari 400/800,
etc. However, note that many of these platforms *also* do not have
compatible interchangeability with their mouse ports.
The Roland samplers used MSX-style mice, and I'm going to bet that the
internals or "brains" of these samplers contain a lot of the same logic as
the old MSX-based home computers of the mid-to-late 80s. Just another
standard, using its own standard :)
Sorry to hear that another mouse port bit the dust.
