Over the past couple of months I had been slowly building a new working digital computer to replace the one now on display at the System Source Computer Museum. Hopefully in the not too distant future people will actually be able to go into the museum and see it there :-( 

Well a basically identical reproduction of the original (WDC-1) is now finished! Not to much to say here except that I thought the process of rebuilding would be tedious and boring, but I was surprised at how enjoyable it actually was. Without the anxiety of wondering (despite best laid plans) if everything would work as expected, and the anticipation pushing you (maybe too fast sometimes) to want to see a finished project, I had a very pleasant experience.  I think it helps that there is a good variety of tasks that go into making a WDC: 

By working on a module at a time, I was able to cycle through these task and thus not get too tired of doing any one thing for too long. 

All in all, making WDC-2 was a nice change of pace.
