I asusme there's nothing of use on
http://www.hpmuseum.net/ ? That has
some stuff on larger (than handheld) HP computers and peripherals.
But I still and urgently need the schematics for the
7978 drive. My
I sould be suprised if any published manual contained full schematics.
By that period, HP comptuers were 'repaired' by board-swapping. If you're
lucky there will be _some_ useful info in the boardswapper guide, like
pinouts or testpoints.
I hate to say this, but you may be reduced to producing your own
schematics. It can't be that difficult, I've managed to do it a few times.
