It's a custom serial cable, the pinout is on page 47 of the manual. I changed the original fan too, even though it was a high quality papst the noise was too much, this is the one I used http://www.quietpc.com/na-ds-60.
I was going to suggest that Nad. If people are happy and willing to contribute I'll create and maintain an ABI Boardmaster 4000 thread in "Technical". I think I've only scraped the surface of it's capabilities myself...
Seconded. It would be nice also to merge the useful info from the various ABI threads into one. Or create some links that point to useful content from the other threads. dorkshoei2017-05-16 17:12:53
My ghetto BDO cable unit I made from bits laying around the house. Probably overkill but I didn't want to hack up a perfectly good set of probes to make this. Now to learn how to use it
