HP 9845 Microprocessors

I'm trying to nail down a few bits of information regarding the various hybrid microprocessors contained in the earlier versions of the HP 9845. I recently purchased a large lot of 9845 boards, looks like most of one machine plus the PPU from a second machine. All told, I have four hybrid microprocessors. Two are the 107-pin AEC-variant 5061-3001 processor, one on a revision-A PPU card and one on a revision-B PPU card. The other two are both mounted on a single card, which is presumably a pre-bitslice LPU. Of the two processors on this board, one is a 5061-3010, the other a 5061-3011. From what I understand, the -3010 is the original hybrid used in the 9825, and I read something somewhere that lead me to believe the -3011 is a microcode variant of the standard -3010. Are both of these processors part of the LPU? Most sources refer to the 9845 having two processors, the PPU and the LPU, and I haven't found any that say the LPU itself actually consists of two processors. Is the -3011 just a microcode variant of the -3010? Also, are there any microcode variations between the -3001 on a revision-A PPU card and one on a revison-B PPU card? Regards, Micah Mabelitini
