- PC - l600 ® this pulse width continues for more than 300 micro· seconds, the subcontroller proceeds in the same way as the system power-on procedure so that a reset is applied to the system. After the system reset has been cleared, the Z-80 starts operation within 10 microseconds and the Z-80 begins to read the contents of the address OOOOH . (MREQ ® issued) Now, the Z-80 starts to supply clock pulse to the 7-3·3.
then set in the input mode. So, a low signal is issued to PA7 ,.., PAO and P86 at every 1/64 second to discri· minate a key depression. In this instance, a low signal is sent to all strobe lines to sense a key oepression. When a key depression is sensed, that particular key is distinguished after sencling a strobe to each line. As the key input appears on KIN7 ...... KINO of the SC78S2, a row of the keys in a low state is judged to be the row at which the key entry occurred.
(1) Input signa ls are received by the transistor and are output through the open collector and pulled up to VCC using a resistor, as shown in the hybrid Ie BX7269W. A diode is inserted across the base and emitter of the input which will bring the signal below the GNO level (stop bit , etc.) and make it assume to be at the GNO level. Therefo re, the input signal is converted in the hybrid Ie to be handled as a logiC signal. UART RS·232C Interflce Ree,iv, d.

A signal transition is latched on the output side using the pulse by means of the capacitor and characteristics of the Schmitt IC for convenion of a logic signal into the RS·232C interface signat.
PC 1600 2. Remove the eleven screws (see figure) and remove the key PWB (with the FPC PWB) from the top cabinet. NOTE : This job is required for the reuse of the key PWB. 4. How to solder the FPC PWB with the key PWB (1) Apply a thin layer of solder over the soldered portion of the FPC PWB. (2) Cut away 1.5 to 2.0 m illimeters of the tip of the FPC PWB usi ng a knife or scissors, in order to check whether the solder melted at the exposed portiOrt of the key PWB will function when heating at (4).
- PC - I600 c. Lift the PWB with your hand and carefully mount it over the leads of the LSI. When the solder on the leads melts after five to six seconds, remove the LSI from the PYlB using a tweezers (or a small flat tip screwdriver) . d . Clean away solder fragments remaining on the pattern side of the LSI using a solder wick. Then, evenly apply a thin layer of solder over the surface. e. Apply a small amount of solder to the leads of the new LSI , and solder the leads with care.

5. Brief description of floppy disk drive The floPPV disk controller is implemented within the 2.5" floppy disk drive, and the floPPV disk dri ving and head seeking are done bV one motor. The floppy d isk is driven by the belt and the head is seeked using the solenoid and The reason why the reset signal is required at power on is to hold it in the standby mode so as to avoid malfunction in the floPPV disk controller inside the floppv disk unit. com. 4·3.
