Hmmm, a couple places I looked seem to indicate 1600 (PE)
only. I never used a 92181, but am quite familiar with the
92185 (1600/6250). So, looks like it is PE, only.
The 92185 has no density select BUTTON, only an LED to
indicate high density. Density is selected by the ID burst
on the tape, unless it is overridden during tape
initialization from the computer interface.
