*earlier* what i have here is a Sun SPARCstation 1+.

it's going to need a little work but WHAT is that blob of duct tape

looks like a coin cell mod.

on the back, we have the usual semi-cursed 13W3 video connector and the Sun keyboard connector. where am i going to find a Sun keyboard?

i just happen to have one, new in box! i bought this years ago at Weird Stuff Warehouse when they were still around. i have no idea why, but i'm glad i did.

i've also got some Sun mice. an M3 and an M4.

however, they have RJ11 connectors and the keyboard (which is where the mouse plugs in) just has a mini-DIN connector. uh oh.

which brings me back to here. does this mouse, despite the connector difference, use the same protocol?

looks like it is essentially the same protocol as the version of the mouse (type 4?) designed for the SPARCstation. the output is open collector, inverted async serial, 5 byte.

time to build an adapter. the connector is RJ11 (technically 6P4C) but it has these pins sticking out, presumably so you can't plug it into a phone jack.

ahh well, i'll just file some grooves.

adapter!

couldn't find a Sun 13W3 cable adapter so I'm doing this to get to VGA.
