10.3 Gängige Computersteckverbindungen
10.3.1 Netzteilstecker
Typische Netzteile haben 6 Stecker raushängen: 2 Stück zu je 6 pins
für das Motherboard und 4 Stück zu je 4 pins für Festplatten, Disketten-
laufwerke etc.

Mit DOS V 6.0 (and Central Point Software's PCTools 8.0 w/ Drive Map 1.0)
wurde die Möglichkeit eigeführt, zwei PCs über ein paralleles Kabel zu ver-
binden, um Fesplattenlaufwerke von beiden Rechnern aus benutzen zu können.
Die Belegung des notwendigen "LINK DOS 6.0" Kabels ist wie folgt:

Another strange cable I ran into was for a HP Plotter (also applies to
the HP Paint Jet). A standard serial cable would not work, nor would a
null modem cable. Before you go out and buy an expensive HP cable try
making your own from one of the following pinouts.

Most serial port connections only require a few wires to be connected.
The most common types of connections only require:

The above 9 pin connections were 'figured out' using the 9<>25 pin

Full pin 25M <> 25F cables have all pins connected straight through:
25F <> 25M
1 1
2 2
3 3
... ...
23 23
24 24
25 25
thus making extension cables for either serial or printer cable
connections.
Serial cables that have both Male ends or both Female ends are strange.
The pins are connected from<>to the same pin number on the other end
(1-1, 2-2, 3-3, ... 25-25) but since the gender is the same on both ends
these cables are not extension cables but actually CROSS the wires. If
you were to plug two 'same gender' cables to each other thus making a
connection like:
25F > 25F<>25M > 25M
1 25 25 1
2 24 24 2
3 23 23 3
... ... ... ...
23 3 3 23
24 2 2 24
25 1 1 25
you would have actually created an extension cable.
