[volt-nuts] Solartron 7075 reference heater and serial interface

[Fabio Eboli]

Hello, I recently repaired an old 7075,
the reference oven seem opened and leacky,
with what seems silicone getting out.
I measured the heater resistance and is of about 100ohm.
Is this normal?
Here some photos and more details about serial
interface

I'm thinking to connect a micro to the
internal optoisolated interconnection to
bring out the readings, should be interesting
to log the glug signals stats.

Fabio.
