No, mine is an original in an HP binder with that title printed on the 
front. It also has an index that covers the sections I have and those 
sections only (in other words, I think I have a complete manaul, although 
there may have been other versions).

Yes, I have one. Somewhere I have the pinout of the PSU cable (it's just 
+12V and +5V, of course).

I don't have a 9122 to look at, but the 9123 that I have is very 
different to other HP drive units that I've looked inside. For one thing 
it uses an HP custom HPIB buffer chip -- the same one that's used in the 
82169 (HPIL-HPIB translator, I have the service manual for that and it 
_does_ contain schematics). All the other HP drives I've been inside have 
used stnadard (Intel, Motorola, etc) buffers.

I don't, but I have my own schematics for the 9114 (both versions, both 
types of battery pack, etc). I also have my notes on how to set the darn 
thing up (which is remarkably easy). I've seen a 9114 service manual, and 
it was a waste of good tress!

Does this manual contain any useful info? IIRC those drives used a 6802 
processor, not the 6809 used in all later units.

I am _sure_ my 9133H uses as ST225. Or at least the ST225 scheamtics I 
have apply to the drive in that unit...
