The PCB card is 6.075 x 4.85 inch. The female connector of the cards mate with wire wrap pins extending o o through the chassis wire wrap board. The logic cards functions are dis- persed from the reverse ends of these pins through wiring installed using the wire wrap technique. Cards installed in the logic chassis are restricted from vertical and horizontal movement by card guide spacers. o Numerical designators (1 through 99) are etched on the non-component side of the board to identify each transistor. 4:) designator is etched on the non-component side of the board to identify the card type. o o o o o o o A 4-character alphanumeric A matrix code (alphanumeric) also appears on this side. Non-amplifying components such as integrated circuits, resistors, capacitors, diodes, etc., are not marked. Pin Assignments The PCB card contains a 62-pin connector. Connectors are mounted along the shorter dimension on the component side of the board. 83302400 C 7-1 I o o o o o o COMPONENT SIDE TEST POINT o SIDE ETCHED MATRIX TWO LOGIC CHASS IS ROWS PIN IA 4 CJ. 00- o FOIL END • O~~ o --- --- DISCRETE COMPONENTS 3 1 I 2 I 1\, A J o C·\ ~"" .· O "I I @ , PIN 178 O / z ___ ~ PIN~· Q) 21B INTEGRATED CIRCUIT I I(J • •• PIN' o I PIN I o NOT ES: The third line, also The circuit type is a subdivision of the function identifier (specifically a high level amplifier).

In the reference designator (U-A4B), the U specifies a non-amplifying integrated circuit, the A4 is the circuits board matrix location for the package, and the B indicates the section of the package. (A 140 package is a four section package. Each section is a separate circuit. Sections are· identified A through D.)

Wired Functions STANDARD /NON -ST ANDAR,D LOGIC LEVEL INDICATOR The input to a logic function at a voltage other than the standard logic level is represented by a slash across the non- standard level line. Absence of the slash (or absence of an X, see below) indicates a standard logic level on that line. When the input signal to a logic function is an analog signal, the input line will have an X across it. The analog designator is used on lines that normally operate at more than two voltage levels.

Input B is a gate input. When input B is +20v, diodes CRNA, CRNB, CRNC, CRND, CRNE and CRNF are forward biased. The voltage between CRNC and CRNE and between CRND and CRNF is clamped at approximately +2. Ov. With all diodes forward biased, the read sigi1.al can pass to the amplifier. When input B is ground, diodes CRNG and CRNH clamp the voltage at +0. 6v. biases the input diodes. The preamplifier is a three stage amplifier using an emitter follower output stage for low output impedance. The integrated preamplifier has discrete component ac and dc feedback. AC feedback is provided by CNE and RNH in the top half and CNF and RNJ in the lower half of the circuit. The signal is brought back to the emitters of the input stage to increase input impedance. DC feedback is provided by RNG, RNE and CNC (to ground) in the upper half and RNK, RNF and CND (to ground) in the lower half of the circuit. This feedback helps to stabilize the output. Capacitors CNG, CNH and CNJ, and CNK filter noise from the +20v and -20v power supplies, respectively. The electrolytic capacitors filter low frequency noise. The paper capacitors filter high frequency noise. Open loop gain in the amplifier is approximately 180. c o This reverse No read signal can enter. Closed loop gain in the amplifier is approximately 3 O.

A "1" at B turns transistor QNA This provides base drive through RNC to QNB which turns on. The output at C is now the same as the input at A except for the emitter-collector drop (0. 5v) across QNB. o o With input B at ground, "0", QNA is off and base drive to QNB is provided through the 4. 7 -volt Zener diode, CRNC. The voltage drop from A to C is Vb e plus V. z Resistor RND improves circuit operation by increasing the Zener current. o o «) 83302400 A 7-9 - ..'--." ......•.- ••.........•- -•..-.-.-......- .........- ..--..-- ...- ................._.....__........ o o o +20V 8 ...... .. ....................

If a head requires replacement refer to the Preface of this manual for the publication containing the Maintenance section. Head/Arm Replacement procedure. Refer to that section for A head is defective and needs replacing if any of the following conditions exist: 1. Consistent oxide buildup on head indicating repeated head / disk impact. 2. Appreciable oxide buildup located primarily on the edge of the ferrite in~ert, indicating a warped head. 3. Oxide or wear over 1/2 of the head face surface. 4. A head which is scratched over 1/2 of the head face surface. 5. Concentric scratches on disk surface. 6. Audible ping indicating that the head is hitting -the disk surface. Inspect the head for imbedded particles. DISK PACK REPLACEMENT CRITERIA The disk pack is designed to last the lifetime of the equipment. Repla-eement of the disk pack is required only if excessive runout (see Disk Pack Runout Check) is encountered or o o o physical damage to the pack results in the loss of recording ability. . A disk pack is defective and needs replacement if any of the following conditions exist: 1. Damage to the disk pack resulting in a bent or broken disk. If a disk is bent perform Disk Pack Runout Check procedure. 2. Gouged or scored disk surface causing the loss of stored data. 3. Imbedded particles in a disk surface that cannot be removed by cleaning and are causing damage to the heads. () - o o o o o 83302400 A 7-43 Disk Pack Runout Check This procedure determines whether a bent disk pack may remain in use. If the 'disk pack o o o fails to meet the requirements of the procedure, it should be returned to the manufacturer for reconditioning. 1. , Open cabinet top cover. " (, ,l 2. Install the disk pack to be checked on a DSU spindle. 3. Grasp the pack cleaning brushes, override the shaft detent mechanism, and rotate J. (" the b::-ushes into the disk pack. 4.

Turn the bezel of the dial indicator to indicate zero. Orient the dial indicator so that the plastic tip is not only contacting a disk surface but is deflected for an indication of approximately O. 020 inch. Tighten dial indicator in this position. Turn the bezel to set the dial indicator to zero. 8 DISK PACK DISK PACK RUNOUT GAGE Figure 7 -32.

Manually and slowly rotate the disk pack one full revolution while carefully observing the dial indicator. 7. If a total deflection of O. 012 inch is encountered in step 6, recheck the indication. The total deflection must occur in a disk circumference of 4 inches or more. 8. Repeat steps 5 through 7 for the 19 remaining disk surfaces. 9. Rotate the pack cleaning brushes clear of the disk surfaces. 10. Remove the disk pack and the disk pack runout gage. o o o o o o o o o o o The sum of the deviations (to either side of zero) should not exceed O. 012 inch. 83302400 A - __ ~_u,' o o o .~"\ (......"'l' (: • J' c;, (~; ( " ...
