 I'm going with a 74hc574 because, why not...I already use it everywhere else.  Hopefully it doesn't come back to bite me, I don't think it will.

 Well, that's it for today, hopefully tomorrow I'll have more time for this.  I doubt it, given the hours I want to work and all that.  The next best chance will be Saturday evening, or Sunday morning/afternoon&evening.  
 
-I think my next target will be to finish the current clock, and start testing out everything else(PC, ALU).  I only had a couple errors in the registers module, namely the DIR pin(needed to be 5v instead of ground to get it to go A->B), a wire was in the wrong order for one of the decoders, and the order is messed up.  But, that's not too bad given the literal mess of wires.  I _might_ have swapped a bit somewhere, but that'll take thourough debugging with a completed system, or at least something much further than what currently exists.  
-It's also getting closer to the time where I need to purchase a board to start building it all out on, as that'll get me to the point where I can hook things up to the bus for real, as right now I have 6 completed(ish) modules, and 3-4 more that I need to wire up that will all have to be connected to the bus.  And once I have a permenant bus wired up, I can start doing simple things like counting up and down, outputting values to a register, etc.  Half of this build will be overcomplicated but it's MY build, so I do it MY way.  :-)

+## Finishing the clock
+
+I finally finished the clock, it was really just hooking up the logic gates and the third 555 timer.  Now that that's done, I can now do basic clock stuff.  However, there's not much that I can see with it as I don't have the ALU stuff hooked up.  
+
+I've also decided to upgrade the main bus to 16 bits, as I have plenty of breadboards, and it really doesn't bother me.  If anything, that'll allow me to potentially expand this to 16 bits if I ever feel like causing that much pain and stuffering.  That would be a total redesign of a bunch of parts, like the ram, alu, and registers, but I _might_ do it.  
+The main advantage of that is that it makes some instructions easier, like the program counter in/out, instruction register in/out(maybe), and that's about it.  
+But that might be a fun challenge for the future.

+Enough about the future, we're stuck in the present(always).  
+I don't want to hook things up to the bus just yet, as I don't have a board ready.  But I might measure it up soon and buy something from home depot, as they should be able to cut it for me.  I just don't know the final height of it, as I know I need more breadboards below.  Need to prioritize that asap(nevermind that the left half of the pc isn't even wired up!  )
