I picked up a TANDY FD501 complete. First original TANDY FD I've ever
owned. Drive 0 only. Only one R/W head, unfortunately. What I find
curious is that both the DS0 and the DS1 bridges are soldered (not to
each other), as if the appropriate jumpers were in place. I checked the
ribbon cable and it appears fully intact and original. I've not had the
chance to try it out. Is it normal for these units to have DS0 *and* DS1
jumpered? Can't figure that one out.

Other thing. The RS Disk Basic ROM is the old smaller variety. Is it
possible to rig a 27xxx chip into there?
