PROCESSOR TECHNOLOGY CORPORATION
CUTS, COMPUTER USERS TAPE SYSTEM
SECTION II
2.3.5
Use of Clip Leads
NEVER attach clip leads to the top edge of the CUTS PC board.
To do so can short the +8, +16 and -12 V dc buses to one another.
2.4
REQUIRED TOOLS, EQUIPMENT AND MATERIALS
The following tools, equipment and materials are recommended
for assembling and testing the CUTS Module:
1.
Needle nose pliers
2.
Diagonal cutters
3.
Scredriver
4.
Sharp knife
5.
Controlled heat fine tip soldering iron, 25 watts
6.
60-40 rosin-core solder (supplied)
7.
#24 bare wire (supplied)
8.
Volt-ohm meter
2.5
ORIENTATION
The heat sink area (large foil area) will be located in the
upper right-hand corner of the board when the edge connector is at
the bottom.
In this position, the component (front) side of the
board is facing up and the solder (back) side is facing down.
In
addition. the IC legends (Ul through U4, U8 through U15, etc.) will
read from left to right.
Subsequent position references in the in-
structions related to the CUTS PC board assume this orientation.
2.6
ASSEMBLY-TEST
Refer to the assembly drawing in Section VI.
CAUTION
THE CUTS MODULE USES MANY MOS
b~D
CMOS
INTEGRATED CIRCUITS.
THEY CAN BE DAM-
AGED BY STATIC ELECTRICITY DISCHARGE.
HANDLE THESE IC's SO THAT NO DISCHARGE
FLOWS THROUGH THE IC. AVOID UNNECESSARY
HANDLING AND WEAR COTTON--RATHER THAN
SYNTHETIC--CLOTHING WHEN YOU DO HANDLE
THESE IC's. (STATIC CHARGE PROBLEMS ARE
MUCH WORSE IN LOW HUMIDITY CONDITIONS.)
