Tube🌿Timewelp, how'd i get into THIS situation? let's rewind...
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.
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.
four months later 
i made the Video Snake Oil board that can adapt 13W3 (any type!) to VGA. you just wire up the little pads to whatever your machine needs.

Anthony Sorace@a for the video you can use this adapter: https://github.com/schlae/13W3
for the keyboard it is literally just a serial port, you could do it with an rpi or an arduino quite easily
shuppy@delan @tubetime Oh, this looks awesome! I love that you put in stuff like the idprom macro; great touch I wouldn’t have thought of. I’d still like to get something going with the (non-pico) pi because I want to treat it as a wifi pseudo-bridge, but given how far underwater my project list is, maybe I’ll start with this.
