Hah! Wirewrap the bugger!

I was working on a modernized version of my old computer, remember? I have the basic computer and the memory (up to 16 megabytes for the old dog  ) ready. Now I'm not sure wether I should first build a prototype on perfboard bfore I have a buggy PCB made.

Go straight to 2 layer - the bugs in your design can be fixed with judicious cut and wire, and you don't get the loose connections and crosstalk that make life such a PITA...
I've played those games, and it's a lot cheaper and less stress to go to straight to PCB even if you know you're going to bin it fairly quickly. Just socket everything and life gets pretty sweet!

Ok, I'm convinced. I made some changes in the PCB layout and over the weekend I will check wether the Sub-D connector will fit, wether I can replace the EPROM by a compatible EEPROM, recheck the clock and baudrate generator and memory addressing and then let's hope for the best.

Done that, Wirewrap is easier to debug if (when) you make a boob

Ish. It also causes a pile of problems all of it's own, what with fallen off wires, dodgy connections, crosstalk, ...

Breadboards are very noisy. If possible, test your design at a very low clock frequency and even then noise can still cause glitches. With an oscilloscope you can see errors of that kind quite well. Even under good circumstances you can hardly expect to see a nice square signal.

I have found breadboard and strip board a good antenna for picking up long wave radio...

Not if you encase the pin in solder, but then you loose the ability to swap around, what I have done in that situation is test everything and if I can't see a problem get busy with the soldering iron!
|
|
|
|
|
That is called "makin' Pappys way", I have done that in my garage, I have a feeling it would an 'elf & safety' violation to do it on company premises...

That's too comfortable. Use an acid proof pen and draw your pads and traces directly onto the copper.

I have not used it myself, but this one[^] has been recommended to me.
Thee is a free version that is limited to 250 pins or soldering pads and only two layers.

Way back long ago I worked at a PCB development company. Amongst the things, even back in the 1980's that was important is that boards are typically multi-layer. This allows smaller and more complex circuitry. Possibly more than you need worry about, but this type of planning, topographic layering, in some ways simplifies the design (no need to have weird routes as "wires" can cross without touching), but could increase the cost of the software.
Note that plating through the whole was an important part of these designs - so that when those wires cross and you want them to meet at a connection (drill hole) they do.
At that time, the company even had a machine that drew with wire as an alternative to the etching process - and since the wire was insulated, they needn't worry about crossing lines unless they wanted them to connect (drill, plate-through).

This I have used a really long time ago.
Easy-PC PCB Design Software by Number One Systems[^]
At the time it had no auto-routing but was the only affordable one I knew of. Not too bad for the price but I've no idea how it is now.
Protel (I see they changed their name) was really good, during the 1 month trial. Was $5000 then...
|
|
|
|
|
Altium DXP would be my choice, but KI Cad I have tried it seems usable. Protel is/was good but expensive, I still get cold sweats from using it at Uni. It was the DOS version where you could assign your own short cuts, I rarely did so hitting F1 could do anything! 
|
|
|
|
|
I use Altium myself and can highly recommend it. Eagle cad is quite popular with the DIY/Arduino crowd.
|
|
|
|
|
I think the sys admin and I tried TICAD free and seems quite feature rich down side open source!  Recommend Eagle as I have used before but could not find the refernce I used, think it was amalgamated with RS Components in the UK...

I'll be back in approximately 16 hours and 30 minutes. In that time I will get some sleep, get through a work day and then ensure I have a big drink.
If all goes according to plan I will be back on Code Project at 18:53 drunk posting to commemorate 18 years since Melanoma took my little sister.

What do you get when you cross a joke with a rhetorical question?
The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism.
Do questions with multiple question marks annoy you???
