[rescue] Sun 3 keyboard/mouse options?

[Steve Hatle]

It appears Sun actually sold an adapter to use the Model 4 keyboard on 
the Sun 3, part numbers are

530-1478
530-1479

Same cable, different lengths. I've also found the pinouts to make my 
own; I have some 9-pin male shells and I'll probably liberate the female 
DIN-8 connector from a trashed keyboard to make the adapter.

I will start small with serial connection first. Will also need to 
research how to get this guy net-booted and eventually an install on a 
drive in the shoebox. I'm not holding out hope of getting anything done 
with the tape drive or tapes.
