16 pin IC sockets.
17)
Insert and solder each of the fifteen .1 uf disk capacitors
C3 through C17.
18)
Insert and solder each of the two 33uf tantalum capacitors Cl
and C2.
as indicated on board.
19)
Insert and solder the one 2N3904 NPN transistor Ql, orient as
indicated on Assembly Diagram.
HEAT SINK AND REGULATOR INSTALLATION
20)
Bend the leads of the 7805 regulator at 90° angles approximately
1/4" from the bottom edge of the regulator to facilitate inser
tion on top of the heat sink.
21)
Insert the #6 screw through the regulator and heat sink and at
tached washer and nut from back side of board.
to hold the heat sink in proper vertical position while tight
ening the screw in order to prevent shorting to adjacent traces.
Solder regulator leads.
22)
Finally, plug the one 8214 24 pin IC into the 24 pin IC socket
located at E 2 .
N OT E :
1)
The 16 pin IC socket and header located at C4 is to be used for
interrupt interval select.
2)
The 16 pin IC socket and header located at D2 is to be used for
interval priority select.
3)
The two 16 pin IC sockets and header located at E4 and E5 are
to be used for output port address select.
