[rescue] SPARCstation SLC connector pinout

[Lionel Peterson]

From the outside looking in (I've never owned either an ELC or an SLC), I suspect there aren't really that many connections *required* to get the mainboard working - power, Ethernet (AUI) should suffice for a minimally viable system - video, keyboard/mouse, sound, serial ports could likely be ignored, though now that I write this, a serial port would likely come in handy, to overcome booting issues (dead NVRAM, boot command, config networking).

I suspect that's what David's friend did to convert the bare boards he had into web servers, just the minimum.

This seems like a lot of work for boards of unknown operational status, likely with dead NVRAM, but then again, I've been know for rehabilitate systems of dubious computing value in todays environment, so I'm not saying "don't do it", I'm just acknowledging the effort you're facing.
