Day of Frustration

I suppose I did get a few things done today, but it seems like I've achieved nothing. I went to the shop, I did a couple of loads of laundry and I charged some EV batteries. I managed to get a photo of the SID breadboard, too:

I see, it looks pretty neat. Say, what's that chip next to the sid?

There's a 74HC393 counter chip next to the SID. I use it to divide down the 16MHz clock to 1MHz to act as the Phase2 signal for the SID. The 16MHz oscillator is in the rectangular silver can. The Arduino will read the Phase2 signal and synchronise its simulated 6502 bus cycles with that.
