I see a Commodore 1830 (two-button mouse designed for the C-64 joystick port)
on sale for $40.00. Is this the same mouse as what the Amiga uses?
(electrically and mechanically?)
Is it worth getting at this price? Anyplace it can be had for less?
Is there a three-button serial mouse (preferably optical) that can be had for
about this much?
Thanks.

Nop, the mouse that you saw for the C-64 responds to the computer as a Joy-Stick would, there for it would not work with the Amiga.... -- /// Amiga Power User - Mr. Chima Ngene (chima@dasys1) /// /// {UNIX, & DOS, ETC} Programmer.....

The first, older, model is the 1350. It has a four bit micro in it which interprets mouse movements and asserts the joystick direction lines accordingly. This make it totally compatibly with all joystick input games etc, but terrible at drawing. For example, you can draw great squares and octagons, but circles just seem to have eight sides. The second mouse is the 1351. This mouse has two modes. The first mode is just like the 1350 mouse. So compatibilty is assured. The second mode is a new proportional mode where the mouse uses features on the SID chip, and a small 60 hz interupt routine to effect a true proportional mode. Great circles, but can only be used with software which expects the mouse. GEOS has a special input driver for it, and code examples are provided for the mouse on a disk shipped with it and in the mouse's manual. Selection of the mouse's operating mode is done at powerup by holding down the left mouse button for joystick mode, or simply not depressing a button for proportional mode. As for the 1830, I haven't heard of that mouse. We do have a mouse for our series of PC clones which is just like an amiga mouse, but I do not think 1830 is its number. Could be wrong on that though.
