[10] The Macintosh TV is essentially a Performa 520 that can switch its built-in 14" Sony Trinitron CRT from being a computer display to a cable-ready television.

Later Apple would issue a custom black Performa 5420 in markets outside the United States with many of the features of the Mac TV.

Apple's similar TV tuner card was a popular option for later LC, Performa series, and select models of Power Macintosh G3 beige computers.

Additionally, it features an Antenna In (F-type RF Connector), Composite Video-In, Stereo Audio Input (RCA-type), and a 3.6 V lithium PRAM battery, boasting a Gestalt ID of 88 and supporting 32-bit addressing.

Although the built-in tuner capabilities are lost, installing an LC 575 motherboard is a common method to step up to the significantly faster 68040 processor.
