Many readers outside of the USA have requested this netlist, so
here it is !

Parts list and netlist for the Parallel Port Logic Analyzer.
If you have questions/ problems with this netlist please e-mail me
at stevem@tanisys.com   I based my version of the circuit on an
article in Electronics Now.  I am not the creator of this work, so
I can assist only in telling you how I made mine.
In my version all parts at through hole.  You must provide +5volts
to this version of the circuit.  I used a 7805 and a nine volt battery.
Please get the data sheet for 74HC14 and CD4060 before proceeding.
Then using these data sheets convert the netlist to a schematic.
In the netlist, the number in parenthesis is the pin number.
(A) stands for diode anode
(K) stands for diode cathode
(+) stands for positive terminal of cap
(-) stands for negative terminal of cap
Two terminal devices (resistors and caps) pins are labeled 1 and 2
The 100K resistors only provide isolation between the five test probes
and
the 74HC14.  TESTWIRE refers to the wire used to connect the unit under
test to the analyzer.  Six connection wires are required to the unit
under test!
That is don't forget to form a common  ground.


R1,R2,R3,R4,R5 = 100K ohms
R6 = 1M ohms
R7 = 5.1K ohms
C1,C2 = 20pF
C3 = 0.1 uF
C4 = 10 uF
X1 = 5.0688 MHZ parallel cut
IC1 = 74HC14
IC2 = CD4060
D1 = 1N4148 OR 1N914
D2 = 1N34A
DB25 = DB25 MALE SOLDER CUP CONNECTOR (must mate with printer port)

Options:

With some slight loss of accuracy, a 4MHZ or 6MHZ crystal can be subbed.
If you try a 4MHZ crystal then   D1(A) connects to IC2(14) not as above.
If you try a 6MHZ crystal then   D1(A) connects to IC2(1) not as above.


Good Luck,
