Wire.





Ground wire. If you have a shielded cable then use
the shielding for the line marked as "GND" on the diagrams.





Not connected wires. Note the small split in the
horizontal wire.





Connected wires. Note the small dot, representing
the solder blob.

Amplifier. It consists of one transistor and one
resistor. The transistor has three pins. The collector (marked with C) should
be connected to the wire coming from the Commodore end of the cable. The base
(marked with B) should be connected to the wire coming from the PC end of the
cable, through a resistor. The emitter (marked with E) should be grounded.

The first picture shows the amplifier. The second picture displays a BSV52
transistor (SOT-23 packaging) as viewed from above. The third picture displays
a 2N3904 transistor (TO-92 packaging) as viewed from below, where its pins
are. Note that the pin layouts are specific to the transistors; others may
have their pins laid out differently.










Diode. Their cathode end is marked with a small
band, which corresponds with the direction the "arrow", representing the diode
in the circuit diagram, points to (on this picture, the right side). In all
tables, the right column shows the pin the cathode should point to.





Exclusive-OR gate. Their output corresponds with the
direction the "arrow", representing the exclusive-OR gate in the circuit
diagram, points to (on this picture, the right side).





Inverter. Their output corresponds with the
direction the "arrow", representing the inverter in the circuit diagram,
points to (on this picture, the right side).





Resistor.

Connectors

DIN plug, 6-pin. It is displayed on the diagram as
viewed from the back side, the solder side. On some DIN plugs, the pins are
marked with small numbers.





DIN port, 6-pin. It is displayed on the diagram as
viewed from the back side of the Commodore drive or the adaptor.





DIN plug, 8-pin. It is displayed on the diagram as
viewed from the back side, the solder side. On some DIN plugs, the pins are
marked with small numbers.

IMPORTANT: This is a DIN41524 type ("262-degree") plug where pins 7 and
8 are "out of circle". On the more common DIN45326 type ("270-degree") plug,
the seven outer pins form a circle, which is mechanically incompatible.





Game plug. It is displayed on the diagrams as viewed
from the back side, the solder side. On some game plugs, the pins are marked
with small numbers.





Game port. It is displayed on the diagrams as viewed
from the back side, the solder side. On some game ports, the pins are marked
with small numbers.





Mini-DIN plug, 7-pin. It is displayed on the diagram
as viewed from the back side, the solder side. On some mini-DIN plugs, the
pins are marked with small numbers.





Parallel plug. It is displayed on the diagrams as
viewed from the back side, the solder side. On some parallel plugs, the pins
are marked with small numbers.





RCA plug. It is available in several colors to help
with finding the matching plugs and ports.





RCA port. It is available in several colors to help
with finding the matching plugs and ports.





S-Video plug (Mini-DIN plug, 4-pin). It is displayed
on the diagrams as viewed from the back side, the solder side. On some S-Video
plugs, the pins are marked with small numbers.





USB plug. It is displayed on the diagrams as viewed
from the back side, the solder side.





User port plug. It is displayed on the diagrams as
viewed from the back side, the solder side. On some user port plugs, the pins
are marked with small numbers, from 1 to 12; there's a letter "B" the left end
of the upper row, which corresponds to pins 1-12, and a letter "A" on the left
end of the lower row, which corresponds to pins A-N.





User port edge. It is displayed on the diagrams as
viewed from the back side of the Commodore machine or the adaptor.





XA1541 mini-adaptor port. The 5-pin edge on the rear
of the XA1541 mini-adaptor. The port is displayed on the diagrams as viewed
from the rear of the adaptor.
