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.

Photocircuits' 1000/0 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 adj ustment; are easily loaded; will trans port and read crude splices; and can be clock syn chronized with a computer up to 300 cis, 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.

It also offers interchangeability of media (mag netic tape to paper tape, etc.). Key to this highly reliable system is the Potter M906 IT Magnetic Tape Transport. Thishigh';speedrecord/playback transport is equipped with all solid~state electronics mounted on individual plug-in circuit boards. Atensioll arm slack loop system com bined with patented dual vacuum buffer provides smooth cycling of the tape at stepping rates of 200 per second. In addition toits application in telephone line transmission sys tems, the versatile M906 IT is extremely useful in modern high density recording systems,providing data transfer rates of up to500kc.

For the Philco 1000 inputs information from any system's word size that is a multiple of 6 data bits (12, 24, 36, 48, 54), and outputs the same information in any multiple of 6 bits. The secret is in the Philco 1000's exclusive N-register. Turns up the volume of the Philco 212 Fast, economical system conversion is just one example of easy transition to a host of new Philco processing ec~nomies. The Philco 1000 h~ndles Input/Output conversion (binary-to-decimal and decimal-to-bin8:ry) and relieves the Philco 212 Central Processor of input formating and verification, file searching, and output editing.
