The Micromys V3 adapter finally arrived (I just used the $8.00 Royal Air Mail option). I plugged this adapter into my trusty 2000HD, and it works flawlessly. It works fine with USB mice, and the one wireless I have. With the DIP switch settings set to Amiga w/wheel, it loads in the drivers for the wheel which also works flawlessly.
Then I tried it on the C-128. Again it worked flawlessly (as a 1351). This is great considering the prices 1351 mice are bringing.
This adapter costs about $3.00 more than the Cocolino, but it does a lot more. So far I have tested about a dozen mice that all worked - Logitech and some off brands, USB and PS/2 (all laser type though).
All in all I am quite happy with this little adapter - looks like I will buy another one some day, if I start using the C-128 more.
