Well it turns out I have a couple of spares, but maybe someone closer would be easier (Madison, WI 53711) I have an MS11-LB, 64Kw, M7891-BB and two MS11-LD, 128Kw, M7891-DB and an M7891-D? So, two of these are newer revisions (rather than M7891-xA) - I have no idea what the difference is. On that last one I probably didn't record where it was D, DB or DA I also have quite a few RK05 packs and would be willing to sell one (and I have boxes to ship boards and packs in). The ones I am most willing to part with would need their open/close springs removed, as they are broken and dangerous to the platter in their current condition, but are otherwise fine. I would just remove the spring. $20 for a pack is what I usually price them at, plus shipping. (PayPal, preferably) The board would be a loan (with compensation for time spent if it is bad *and* gets fixed) ;). Let me know - might take me a couple of days to hunt the board down and remove the spring and re-test the pack and pack everything up and ship it. (in my 11/34 which runs @rkunix V6 just fine. ;)) JRJ
