I have this, however it's in multipage lzw compressed tiff format, not
PDF. I'll gladly send it your way on condition that you'll turn it into
a proper PDF so it can be put up somewhere such as lisa.sunder.net or
bitsavers. :-)

Anyone happen to know:
a) The correct voltage* for the supply to the HDA (ST506),
b) Whether the comms cable is wired straight through? (This for an
Apple /// Profile - I'm not sure if the Lisa variant is different in
this regard). I'm pretty sure I just used a straight-through cable
many years ago, but confirmation would be nice.
* I'm getting +16VDC on the one here (with the logic supply given a
suitable dummy load so that it produces a regulated +5VDC). I don't
particularly want to toast the HDA if that's supposed to be something
like 12VDC... possible that the supplies are essentially separate I
suppose, and the HDA output needs its own load before it'll regulate
properly.
I thought there was a service manual for the Profile (Lisa or /// I'm
not sure) floating around a decade or so ago - doesn't seem to show up
under Google though and it's not on bitsavers :-(
