In 1985, Tandberg's TCD 900 series of professional cassette deckswere built around an eight-bit microprocessor with 32K of EPROM memory.According to a Tandberg ad, the cassette decks were designed "as analternative to the practice of using inferior home tape decks forprofessional applications."
The TCD 910 was intended to replace reel-to-reel and cartridgemachines in many applications. Touting its high specs, the deck was"capable of producing tapes at sound and silence levels beyond thatrequired by broadcast and studio requirements." It offered a real-timecounter and auto-locator functions.
