I know it wasn't. The original was a Tandon 50. But the TEAC
FD-55GFR (in various flavors) was used in a lot of systems and
at least one website said they were used in the 4P. It is an
extremely configurable drive that I have used for numerous DEC
systems (even the infamous RX50!) I have several of them and
it should work just fine if I can find the magic jumper combination.
