Capstan r ves are mechanically switched by a solenoid when changing from 30 IN to 1.8 - 3.5 US variable speed range.- Some components of the M90 are being relocated to make room for the low speed motor. It was noted that on had been, made for 50 cycle operation of the wait, id that this could be accomplished by changing d A o drive capstans (as is done in the _ M series) by attaching the proper site capstan to the drive motor shaft. In other respects the prototype recorder con! with specifications. ventional $90 tape transport was chocked to determine ease of rewinding tape for repeating difficult portions of a transmission. With a little care this may be done by operation of the STOPP MM, and PLAY switches on the transport. If the tape is allowed to cone to a full stop after the STOP is activated and before the ROM is started there is no possibility of breaking the tape. An an alternative, the 990 has a CtX function whereby the tape friction in decreased by releasing the Jam roller and the tape may be rewound manually. This would be a slower procedure. 25X1A9 25X1A 25X1A 25X1A5a1 5.
