So without having mom around to deflect Hudson for the weekend, I got basically zero accomplished and now I'm under the gun to finish my lab for tomorrow. Lame because I know how to do it, but even though I "unit tested" a lot of the individual modules, I still get the feeling it's not all going to work when I put it together. Not the least of the reasons is because I found myself writing a perl script to convert the binary-looking output of a spreadsheet I'm using to write the microprogram into hex. Here's the resulting ROM if you're curious:

For the curious, that's (if it ends up working that is) some tiny bits of code to make the fetch and decode portion of the fetch-decode instruction cycle of the computer we're building. Now cross your fingers and hope the whole thing works; we'll know in the morning because right now, all those tiny little lines are blending together so I'm leaving it alone for the night, for better or worse.
