I remember that Dale Luck, one of the original Amiga
engineers,
sold a mirror-pad mouse, and I thought I remember him telling
me it was actually a Sun-compatible mouse. Of course, this
would mean compatible with Suns as of 1986 or earlier, and
not today's.
Could anyone familiar with older (pre-3?) Suns confirm this?
I'll readily accept that my memory of this could be
faulty.
Perhaps a better question would be "Circa 1986, which off-the-shelf
mouse technologies were compatible with the Amiga mouse?"
None without rewiring. With rewiring, one could use most any mouse available
back then. PC bus mice, Atari mice, pre-ADB Apple mice, C= 1351 mice, etc.
I have an original GfxBase optical mouse on my A2000.
The bottom
says "Mouse Systems - Manufactured by MSC Technologies, Fremont,
CA, etc. Model M4. MSC 40215-001/B S/N MSC CZ097242".
Mouse systems... Where have I heard that name? Didn't they make Sun mice? Yes,
it seems so, I've got one here in a box of odd mice. It's a shame I've got no
Sun to match. =)
