3-moottorinen 2-raitainen.

Huippukunnossa teknisesti – ulkoisesti ei juuri moitittavaa.

Englannin kielinen manuaali mukaan.

Specifications:
*Tape transport mechanism: 3 motor tape drive; 2 AC driven spooling motors; 1 AC driven capstan motor, electronically regulated
*Tape speeds: 3.75 ips and 7.5 ips, electronic change-over, tolerance from nominal +-0.2%
