Building a computer from scratch

It's been a busy month. Finding time to assemble the prototype has proved difficult, but after a few setbacks and a seven-hour stretch of soldering yesterday, the first board has been completed.

Mostly completed, that is. I forgot to order the voltage regulator, so the top left corner of the board is unpopulated - something I'd like to have fixed by later in the week. I'm testing it with an external power supply right now, and everything looks good; the chips are detected by Quartus and I can program them without issue, although they aren't doing much at the moment.

Otherwise, it's been a slow month progress-wise. I've mostly been working on the ISA and its implementation, both of which should be done by the end of the month.
