CALIFORNIA CIRCLE 6 ON READER CARD August 1962 Mechanical simplicity ... which yields a degree of relia,bility unattainable by any other paper tape reader! Simplicity made possible through the utili zation of the revolutionary PMI printed motor direct drive servo. Movement of the tape through the read head is achieved by merely starting and stopping a printed motor. The brakes, clutches and pinch rollers that cause big trouble and down time in conventional tape transports are completely eliminated. Line by line cycle: movement of tape (A) over read head (B) is controlled by drive capstan (C)-attached directly to shaft of PMI printed motor* (D); spring-loaded rollers (E) hold tape gently against capstan, keeping tape move ment in exact accord with capstan rotation; advance command pulse accelerates motor, capstan, and tape; as read head detects next sprocket hole, a reverse pulse to motor halts capstan and tape with next character perfectly aligned in read head. ·u.s.

Photoci:rcuits' 100% solid state readers perform posi tive line-by-line reading at up to 300 cis; can change speed and alter it infinitely from 0 to 300 cis without mechanical adjustment; are easily loaded; will trans port and read crude splices; and can be clock syn chronized with a computer up to 300 cjs, eliminating the need for buffer storage. Console, rack-mounted, reel-servoed, uni- or bi directional transports in a low (up to 60 cis) and high (free-running at up to 400 cis) speed range are available. Strip readers and separate spoolers, vari ous tape widths, block .type reading, special input output ratings, militarized units, and remote control can be supplied.

Potter M906II Tape Transports provide maximum relia bility for the PDP-1 system. These versatile, solid state transports virtually eliminate programming restrictions. Potter transports accommodate five tape widths up to 1 ~" and at speeds up to 120 IPS. A tension arm slack loop system combined with dual vacuum buffer provides smooth cycling of the tape at stepping rates of 200 per second. In addition, data transfer rates of 62,500 BCD digits per second are readily obtained using standard recording techniques.
