Several months ago I rescued a big DEC 3000 from a scrap yard. It's loaded up 
with RAM and a hard drive and has a framebuffer in one of the TurboChannel 
slots, but I've never been able to use it since the serial port has an MMJ 

Firstly, can anyone recommend a good place to get MMJ adapters or cables? From 
googling it looks as if MMJ to DB25 adapter cables go for $20-25 at places 
like this:
...and I'll probably go for one of those unless there's something 

Secondly, I don't know whether or not there's an OS on the box, since I've 
never gotten a console on it. I'm sure I could run OpenBSD or NetBSD on it 
with few problems, but that's not very interesting.

Then there's OpenVMS, which I know nothing about and would love to learn. It 
looks like the only way to get it cheaply is to join Encompass as an 
"associate" and then order a hobbyist? Does anyone know more about how to 
obtain OpenVMS, and how well I could expect the latest version to run on this
