AMMRL Colleagues:
I am posting this on behalf of my colleague, Joseph DiVerdi, at CSU. Please reply-to Joseph directly, copied on this note.
Thanks.

> Dear Colleagues,

> I am in the process of evaluating and possibly upgrading an ancient but venerable Varian Gemini-300 spectrometer to VT operation for use in some experimental physical chemistry and instrumental analysis courses. There are a number of approaches to accomplishing this task that are being considered and I've created a sort of laundry list of questions the answers to which might be on the tips of some AMMRL members' fingertips. Some information should be available from Varian and I will make a direct request for that. Apologies for any redundancies.

> - The probe in use is a 5 mm SW, part #969833-00, serial #251. What is the specified operating temperature range for this probe?
>
> - Does anyone have a VT controller, either manual or computer controlled, for this probe/console pair (the console has been upgraded to permit so-called Solaris operation) either for sale or donation.
>
> - Does anyone have any detailed information on the pin assignments of the DB-9m VT connector on the probe? Details on the heater resistance and typical/maximum operating voltage/current? Details on the type of temperature sensor contained inside the probe? Are there any other features to this connector, such as probe ID, that I'll need to contend with (OK, probe ID isn't a good example but I couldn't think of any other example)?

> Any (other) information is welcomed and greatly appreciated.
