This is all very interesting. I just happened upon a Commodore 1351 mouse last week and was wondering if there was any application to the VIC.

This works nicely in VICE when using its paddle emulation ...

And if that is true, even those nice PS/2 adapters to emulate a 1350 / 1351 mouse on a C64 and Amiga won't help any either, eh? Just wondering, because I was playing with VICE emulation with paddle support, and of course, POT X/Y works nicely with a PC mouse, but I have not gotten any real hardware to work on VIC 20 with a mouse / trackball device.

Any ideas, or am I chasing a red herring? Thanks.

As posted previously here, the NEOS mouse works nicely on the Vic-20, but there is no software that uses it (yet). To make it work without interfering with the keyboard, you have to remove a pin on the NEOS or use a joystick cable extension and remove the pin in that.

I was boggled for a long time as to why the C64 1351 mouse which uses paddle ports wouldn't work on the VIC. It turns out it's a matter of 'timing' or refresh rate.

Paddles work by checking how long it takes to charge or discharge a capacitor but this has to be checked at regular intervals. The intervals used by the SID on the C64 and the VIC-I on the VIC-20 are completely different but it is perfectly possible to create a device that can support both rates or even checks for 'a' rate and adapts to it.

Even the VIC-I PAL vs the VIC-I NTSC have somewhat different rates.
