A little background on this model: It was designed by a group called MLT (Mac Like Things) and to be portable (it should have had a 5v ADB power supply; i don't have the AC adapter but it does take 4 AA batteries). it includes the bulky base with the big 50 pin centronix connector. IIRC it was meant to play those wonderful Photo CDs from KODAK. Class 1 laser product. S/N: P133281V856B No remote or AC adapter. unfortunately, i don't have a SCSI connection for anything anymore, so i'm not sure as to whether or not it is operable. it's been sitting in a closet for about 10 years, so hasn't had much use. see photo for condition.
