Next step... Apparently mu original Tandon floppy has bought the farm. Does anyone know what the jumper setting are for a TEAC FD-55GFR-149 for the TRS-80 4P? I tried the usual (like for a DEC RX-33) but that didn't fly. Every sector fails verify after a format. I am sure it's a jumper thing.
The FD-55GFR is a 1.2MB drive, double-sided. The Model 4P used 360K drives (possibly Teac FD-55A), single-sided as installed at the factory. Are you sure that's the model number that was in your 4P?
