With the logic regulator card, the B would be
functionally complete.
Thanks for the schematic. I've started transporting the manual scans
If the component density isn't too high (and I doubt it would be on a
machine of this age), it's often possible to photocopy (or scan?) the
track side of the PCB and use that as the track pattern for that side.
Then it's just (!) a matter of working out where the tracks go on the
otehr side, which isn't too bad given a good photo of the board and a
scheamtic.
into a PCB design tool should it become necessary to
get a new board
fabricated. I'd much prefer to find an origina l though!
Sure... But presumably the board you make will be a plug-in replacement
for the original. So if an orriginal does turn up you could put it where
it belongs. All you've wasted is the time and components ot make the
replica. you've not damaged the machine in any way.
Sicen I suspect HP2116 parts are rare (that's not Ebay-RATW :-)). I think
it's worth the effort ot make the replacement. If it were my machine
that's what I'd do.
