My Mouse-Converters for

as a replacement or substitute
for the Roland MU-1 Mouse


Schematics, Layout and Hexfile are published now so that everybody can build his own mouse converter free of charge!

Roland MU-1 Mouse

As I have some Roland samplers but not enough MU-1 mice I had a look in the internet for a second hand MU-1 mouse. There were only a few mice to get - and these were very expensive. I also heard that there are still some new original Roland MU-1 available - but also very expensive. When I read that the Roland samplers use standard MSX-mice I thought that it is nice to know but these mouse type is not easy to get as the MSX-computers were very rare here in Europe...

So I decided to design mouse a converter that converts the mouse data of a mouse of another computer and converts the mouse information into MSX-mouse compatible suitable for the Roland samplers.

The design of the mouse converter should be powered by the sampler as there is a +5V supply voltage on the mouse connector. A low power microcontroller should be used so that the sampler power supply will not be stressed too much.

The next decision I had to make is the selection of the computer mouse type that should be converted.
 

Available mouse types:
 

Mouse Type
Interface and delivered data
Amiga- and Atari-Mouse, Bus Mouse and InPort-Mouse Gray code (quadrature) mouse type, Button switches as direct signals
PC-Mouse (Microsoft, Mouse Systems or Logitech interface protocol) Serial asynchronous interface with 1200 Baud that delivers relative movement and button information
PS/2-Mouse Serial synchronous interface (similar to the PC keyboard protocol) that delivers relative movement and button information

Mouse-Converter for PS/2-Mouse

As the standard mouse these days is the PS/2-mouse I also wanted to design a converter for this mouse. While searching the web for information how this mouse type works I found some projects of "PS/2 to MSX-mouse converters".

The results of the analysis of these projects was:

So let me show you my prototype of the

The files inside this ZIP are the Japanese->English translated files 
that should be published on Anikuns site some day. 
I converted the doc-file into a pdf-file so that it is in a readable 
format even if you don't have Microsoft Word.

The ZIP-file includes the schematic, hex-file, 
connector pinning and documentation.
