Strange i don't remember seeing one with a header at the bottom near the ribbon cable connector...
how about you mike?
I just checked all mine and none of them have the headers. They all have the solder filled pads just like J6 and J7. Strange indeed.
Thanks. I guess this is a special one huh?
Looks like Rev 4.0. The latest and greatest before switching over to the T-Unit. 4.0 is the only Revision that was on both the Y-Unit AND the T-Unit.
sorry op back on track, i'm thinking that boards one of the old y units or early versions. Those tend to have the extra header at the bottom like that.
special? Perhaps, but other that having a connector at j9a/j9b, it looks ordinary to me. It's most likely a prototype of the newer version of y-unit board. The really early y-unit mk boards had "rocker-switch" type of dip switches and a yellow jumper wire running from the bottom of the board to the top.
Later on, they changed the design of the y-unit board, getting rid of the yellow jumper wire and changing the dips to the standard "on/off" type. I think this may be one of the early versions right at the change. That's the only reason i can come up with as to why there is a connection there and not on any y-unit i've ever seen before.

Anyone know if you can plug and play this board set with an original MK 2 cab? How does revision 4.0 differ from the final 5.0 revision?
