My finest C64/128 setup so far


The C128 is a fascinating and unusual machine. It was the last 8-bit Commodore machine before the Amiga and co-existed with the C64 series for a while. They sold ~8 million units worldwide (vs ~17 million C64). I never owned one, but I fondly remember playing with one at my friend’s place and seeing them in computer shops. It’s fully backward compatible with its predecessor in C64 mode, but in native C128 mode it takes advantage of its 128 KB RAM, higher clocked 2 MHz 6510 variant (the 8502), and the improved VIC-IIe graphics chip.…

Still, I promptly accepted the invitation. I participated in a panel that discussed the struggles and strategies of organizing community events.…

Hacking a cheap video upscaler

Building a Frankenstein 64


Last year, I decided that I was going to build a Commodore 64 from scratch. This is the blog documenting the project. It’s no secret that I love fiddling with retro computers, especially those I owned when I was a kid. When I revisit ancient technologies and hardware that were part of my younger years, I’m overwhelmed with that warm nostalgia feeling. But it’s not only that. Understanding how old computers work is also educational and helps me look at the modern world with a wiser perspective.…
