I' �Iodel ��7 �lagnetic Tape System A Model 1607 Magnetic Tape System consists of four Pimpex magnetic tape handlers. The systein is ' self-contained in a single cabinet, including data- handling and control circuitry; 48-bit assembly and disassembly registers; parity bit assignment for each written character; parity bit read-check immediately .following each character written; longitudinal parity ` bi� gencracion and recording at end of block; parity bit detection for cach character read; and cnd of �" � � tape sensing. � Each 1607 tape system can be connected to any of the three bufler input and three buffer output chan- ;� nels, and each � 607 is indepc :s�ently addressable. A �� number of 1607's can be connectcd to a] 604 Com- ;- �uter. Sinnultaneously among these l G07 tape systcros, F; ` three tape handlers can t�e reading, and thrce tapc � handlers can be writing. Each 1607 system has thc ; t facility for simultaneously reading from onc; tapc �=` handler and writing on onc tape handler, whilc the '� :;` �� remaining two tape handlcrs arc rewinding. Any � . � tape can read either in a forward or reverse direction. Magnetic tapes of thc 1607 tape system are com- ��' pletely compatible electrically u.�d mcchanically :'� � with IBM Model 727 magnetic tape handle:-s. �� . �, r,. . ` Rewind Sp�ed . . . . . . . . . . . .154 inches per second Character Transfer Rate . . . . . . . . . . . . . . . . .30KC : 81ock Length . . . . . . . . . . . . . . . . . . . . . . . .
