<br />`, A Model 1607 Magnetic Tape System consists of
<br />fQur An�pex ma�netic tape handlers. The system is
<br />` self:eontained in a single cabinet, including data- -
<br />` handling ancl control circuitry; 48-bit assembly and
<br />'� - disassembly.registers; parity bit assigninent for each
<br />` written chaxaeter; �parity bit read-check immediately
<br />� following each character written; longitudinal parity
<br />` bit`generafiion aiid recording at end of block; parity
<br />bit detection far each char�cter read; and end of N�odef i 6Q5 Adaptor
