HP 9845A service/user manuals?

Hi all -- Anyone have a service manual for the HP 9485A (not the B or C)? I picked up three of these machines in fairly good physical condition just a couple of days ago, but their operating condition leaves something to be desired :). I've looked in the usual places (hpmuseum.net, and hp9845.net) but I can only find the manual for the B/C revisions. My understanding is that the "A" version is different in some ways (not really sure what the hardware differences are yet.) The good news is that one of the three 9845s just required some careful reseating of the cards and ROMs and it now appears to be working correctly (I haven't yet tested the printer (no paper yet) and I'm assuming the tape drives will require a bunch of work, assuming I ever find any tapes to use). I'd love to get the other two running as well, hence the need for the service manual. All three appear to be complete (with I/O, Mass Storage, and Graphics option ROMs), now if I could just get my hands on an HPIB interface... Thanks, Josh
