Got that 145B motherboard in today and stuck it in my machine. Results are it boots with the battery removed, contrast works, 40MB internal SCSI HD works. I taped over the leads to the shorted battery so I can boot with it installed. Bad part is the floppy drive doesn't seem to want to read or format anything (I can hear it working and it ejects the disks pretty good, cleaning disks didn't help). Another thing is once you pop in a floppy the machine starts to have a buzzing noise that doesn't go away when the floppy is ejected.
