Complete new peripherical hardware should - in my opinion - not beeing build from very old crap. There never was a RS232-mouse for the plus/4-userport until today, even a working driver. Nevertheless I posted the PDF with the idea above. The question I ask is, could that be altered to plug a PS/2-mouse to the user port (that might not be that different than an USB-mouse).
I searched the web and found one PS/2-mouse on the market, that can be bought new until today ... and it is black like the 264er and has no batch or label *:

What about trying to connect this one to the plus/4-userport and perhabs building an interface smal enough to be put into the mouse itself? A small production rund from one of the shops, like sharewareplus, will sure find its customers, I think. Especially when a driver for GEOS (might that be GEOS 3.54?) comes up short after from one of the programming-heros, who are around on this site. 
* Please let me know if there is another new PS/2-mouse somewhere available (but please, no more buttones than Micromys or a possible userport-interface are able to support)
