Initially, I used Packer to generate a virtual machine image, which I would then clone onto the disk of the machine I wanted to configure. It worked very well for server templates, but for a dev machine, it was a bit of a patchwork solution. On top of that, I decided to look for a Packer alternative because of Hashicorp’s licensing changes (a decision I still struggle to accept!).
Five boards landed above the $100 mark this year, ranging from $199 to $590. This is where we see some serious silicon, a newer SoC vendor making waves, and one board that’s in a category of its own.

But the big thing that keeps biting us bites us again: the increased line rate means less time for mid-scanline effects, and less code that can run on a scanline. The OTL Atari 2600 has 76 cycles per scanline, derived from its 1.19MHz clock and a linerate slightly off from the spec 15.734kHz. The ATL’s higher line rate drops that budget down to about 40, and then even lower if you drop to a 1MHz clock. And now consider what the 2600’s dot clock is, 3 times the cycle clock. Those are some even chunkier pixels, and remember, the achievable resolution of the 2600 is much lower due to sprite and playfield pixels being wider than the dot clock. We might not need that extra playfield register.
