pdfPS/2 mouse to FMTowns/MSX interface by Anikun.
Build the ps2 to fm-towns mouse interface. JP Grobler did that and it works on his MSX in Meridian 3 and “windows 2000”- msx version.
Replace the MA723 diodes with 1N4148 . You can use a 16F84A/20p

Add a reset button to the PIC – the original documentation mentions the mouse pointer becoming unstable? this should solve the problem.
Cost : PIC 3.5E , rest 1E, 1 hour of soldering, cutting etc.
