#2Love the design of the website, despite the difficult readability of the fonts. Simple easy layout, happy vibes, reminds me of the old days.

#3Interesting. I know some have tried to make faster versions of old 8 bit computers from the hardware side instead.
Here's an FPGA-based drop-in replacement for 65C02 that runs at 100MHz: http://www.e-basteln.de/computing/65f02/65f02/
Not tried in a C64 yet, but he did get it working in a Commodore PET.

#5I love these projects that show what can be done with 1mhz cpu and mere kilobytes of ram, really makes you wonder what we’re doing with the other 99% of hardware performance we’ve achieved since then

#7I'm a bit bummed out that it's closed source - I would've liked to look through the code.

Programmer productivity. As long as this is the bottleneck in determining market success of a product, this tradeoff will continue.

#9It's a GUI OS, not command-line as I expected:

You can’t just "drop in" a faster 6502 (or 6510) into something like a C64. For one, all the serial i/o routines are software bit-banged so parts of the "ROM Kernal" need to be modified. More importantly, the VIC-II chip is the DRAM memory controller and it is tightly coupled with NTSC or PAL signal timings.
Most accelerator boards for the C64 need quite a bit of glue logic to overcome these difficulties.
