 * MTC/MTH magnetic tape, a Standard-GE-100 controller on connector 3 or 4.

 * TPER transfers the current record into CPU memory through the connector.
 *
 * Image format (host file):
 *   record:    uint16 big-endian length, then `length` data bytes
 *   tape mark: uint16 0x0000 (a zero-length record)
 *   end of medium: physical end of file

 *   connector  : 3 or 4
 *   unit       : 0..63
