The cheezy way is to stripe a channel on your analog tape with SMPTE code and have PT slave to it.

for sync,
24-track ---> SMPTE ----> PT via USD

The pro way, is to use have a house sync and have both PT and your tape machine slave to it. But, you stripe after the _first_ transfer so that your SMPTE and your recorded tracks are based on PT's internal timing grid.

Drums ----> 24-track ----> PT

then,
PT (grided) ----->24-track + stripe SMPTE

for sync,
24-track (control + SMPTE) ===>microlynx (re-generates code, internal clock crystal used or Aardsync) =====> 256x WC (to 888) + MTC + MMC (to PT)
