The Apple version uses an included expansion card which contains an 8-bit [[Digital-to-analog converter|DAC]], although hackers created a modified version of S.A.M. which can instead use the computer's one-bit audio output (with the addition of much distortion) if the card is not present.{{Citation needed|date=December 2019}} The Atari version makes use of the embedded [[POKEY]] audio chip. Speech playback on the Atari normally disables interrupt requests and shuts down the [[ANTIC]] chip during vocal output. The audible output is extremely distorted speech when graphic and text display is turned on. The Commodore 64 makes use of the 64's embedded [[MOS Technology SID|SID]] audio chip's 4-bit volume [[Digital-to-analog converter|DAC]], reducing its quality significantly vs the Apple and Atari versions.{{Citation needed|date=December 2019}} When producing speech, the Commodore 64 version blanks the screen as the program accesses memory, although a "light" mode can be activated that leaves the screen active, producing a "gravelly" voice. Active sprites also cause a deterioration in the quality of voice output.<ref name="personalcomputernews19840602_sam">{{ cite magazine | url=https://archive.org/details/mag_PersonalComputerNews063-02Jun1984/page/n37/mode/1up | title=SAM speaks out | magazine=Personal Computer News | last1=Conway | first1=Barbara | date=2 June 1984 | access-date=20 December 2024 | pages=36 }}</ref>
