Wire wrap layout software

[Alan Strassberg]

Looking for software (Win) to do wirewrap layouts for hobbyist
projects. I've Googled to no avail.

Just place the sockets and go for it! I use boards with power planes to
make distribution easy
then there are some tiny brackets that fit over the WW post and touch the
power planes, these
are soldered into place but are not necessary. Next, I install the bypass
caps and solder them
into place. Any non DIP parts are soldered onto a header so that they may
be wrapped and
finally, the logic part of the circuit can be wrapped. It is helpful to
highlight your schematic
when you place a connection so as to eliminate confusion.

And using different colors can help immensely in debugging/repairs.

Cheers!

The author of the Open-Source app "PCB" said this in a related thread:

BTW, anything that creates a netlist gets you 90% of the way there.
The scratching-them-off-as-you-go tip is critical.

I used to just do it stright from the paper drawing, just mark with a pencil as
you go.

The proper daisy-chain technique can make life easier.

In theory maybe, I never bothered and never had any problem.

Having said all that, after the project gets past a couple dozen
connections,
it's easier to lay out and etch a PCB. Maybe before that. Honest.

No way! if your only making a 1 off the bigger the project the more time you
save wire wrapping.

I made 2 assumptions:
1) You made a printable schematic before starting assembly.
Now that you have a circuit diagram in your CAD app,
it's duck soup to click the Layout Editor icon and create a PCB layout.
2) You made 1 mistake somewhere in the process.
Finding a fault on a printed assembly is orders of magnitude easier
than on a wrapped assembly.

Ok lets take point 1 first, a click on the mouse will not produce you a pcb. It
may also take you a long time to get a routed layout if you have a complex
design. Point 2, fault finding is the same process either way, you can fix a
fault on a wire wrap but you can only bodge a pcb fault. I allways check the
connections with a meter before pluging in the chips as it doesn't take very
long. If you made a mistake in the scematic then you could have a real problem
fixing it if you have made a pcb.
