Building your PIC-TV is quite simple. The circuit board has outlines for each part. These
outlines correspond to the part numbers listed in the parts list. If you still are unsure about the
placement or orientation of a part, check out the pictures of an assembled PIC-TV on our
website at

1) Orient your circuit board so the side with the white diagrams faces up. All parts must be
installed on this side.
2) Start with the resistors. Install R1 through R5 along with C1 & C2. Refer to the part list for
resistor color codes. C1 & C2 look like green resistors.
3) Install the IC Sockets for U1 and U2. Make sure you install the socket so the notch is on
the same side as the small box on the circuit silkscreen. Pin 1 of each socket should be
installed in the square solder pad.
4) Install the crystal (X1), which is located next to U1. Insert the crystal through the holes in
the crystal insulator and then insert the crystal into the circuit board for soldering.
5) Install the remaining capacitors C3, C4, and C5. NOTE! These capacitors must be
installed with the proper orientation. C3 has a stripe with a minus sign in it on one side.
Install C3 so the side without the strip faces the + symbol. The long lead should go into
the square pad. C4 & C5 have a stripe and + symbol on them. This lead under the +
symbol should be installed in the square pad so it faces the + symbol on the board.
6) Install the transistor Q1. Make sure you don’t overheat the transistor when soldering it into
place. Make sure you heat each lead less than 3 seconds. Use an aluminum alligator clip
on the lead being soldered to dissipate heat if you need longer to solder each lead.
7) Install the IDC headers, J3, J4, and J5. When installing J4, make sure it stays straight.
8) Install the SIMM socket S1
. The SIMM socket must be installed a certain way or the
BOB-II will be damaged.
The SIMM socket has two small plastic posts on each end with
tiny pegs that point horizontally. The socket must be oriented so the pegs point AWAY
from U1. When looking down on the socket, there is a thick edge and a thin edge that
surround the socket. The thick edge must be closest to U1. You’ll also see that the
socket groove extends all the way to the metal clips on one side, but there is a plastic
insert on the other side of the socket. The SIMM socket should be oriented so the side
with the plastic insert is FARTHEST from the video jack (J6). A final check involves the
BOB-II. It is installed by placing the gold edge connector into the SIMM socket at a 45-
degree angle. DON’T SNAP IT INTO PLACE. Simply check to see if the edge fits into
the socket all the way across. If not, flip the socket around. The BOB-II and socket are
keyed so the edge only fits in one way. If the orientation is correct and the BOB-II fits in
the socket install S1 so the BOB-II components face U1.
MAKE SURE THE BOB-II IS NOT INSTALLED WHEN SOLDERING S1.
9) Install the terminal blocks J1 & J2. The terminal blocks slide together using small
dovetails. Attach the terminal blocks together and install them together where J1 & J2 are
marked on the circuit board.
10) Install the LEDs D1-D3. Make sure the flat edge of the LED orients as indicated on the
circuit board. Refer to the parts list to see which color goes where.
