Hmm.. I have MicroniK's classic tower's busboard (the one with 4 isa, no pci) revision 4.02. I don't remember exactly now, but I had to send it for repair to get it work with certain accelerator, that long time that I don't remember was it with b1230-IV or b1260. Local dealer made fix for it and after that it has worked fine... I never had any problems with PSU.. it worked fine with power to a1200's mobo from PC psu.. never had connector on busboard.
