What were the rules for logging "simulator" instrument time in 1994 (non-full motion)?
This answer is somewhat non-responsive but may be helpful.
In the 70's I utilized training devices, both in preparation for an instrument rating, and for currency. The training device had a plotter and would tract the path flown.  As I recall it was a regulatory requirement that a CFII or an IGI (Instrument Ground Instructor) provide training for all simulated time.  It was logged as simulated instrument time, and instrument instruction received.
Simulator time on the device was not acceptable for any ratings or currency, unless an instructor was present and endorsed the logbook or other record.
As I recall, two inspectors from the FSDO also used this facility.
When I accomplished my instrument airplane rating and my CFII airplane rating, there was no concern either from the DPE who conducted the instrument checkride, nor from the DPE and operations inspector who rode along on my CFI instrument ride.
I will amend this if I am able to dig out the guidance at that time, which as I recall was not an AC, but rather a collection of Letters of Determination from FAA Legal.
