Category Archives: on the move

This took my Python script 207 seconds. My Commodore 64 just crossed the 24 hour mark. I’m hoping it finishes in time to post the article next week! Brute forcing all the primes between 1 and 2^24. But… it’s for science! Yeah, that’s it!!

10 minute lunchtime progress: Part 9 is on prime numbers. Following the SLOW BASIC version of this with an Assembly version. Next is printing in decimal and some speed work. Happy at this point though

Since I’m not allowed to comment on YouTube today, here’s the YMT/Elysium Bitcoin miner using the Ultimate64 in full turbo mode. Kinda cheating and feels dirty: 26 seconds. My stock Commodore 64 takes 24 minutes.

The Commodore 64 N.O.O.C.U.L.A.R futbal “project”… I can’t say it’s the craziest idea I’ve EVER had, but it sure is fun!

Gather around the fire kids while Grandpa recounts tales of yesteryear. It was a time where brave men departed on grand adventures in their simulators…

In case you were wondering, SIMON’S BASIC modulus is 16 bit. Imma need to implement my own to do the next cipher which needs at least 2^24 to match my assembly version

Oh my, what have I started?

This cheat sheet gets a lot of use these days

15 years after we landed on the moon, a Commodore 64 running BASIC could find the prime numbers between 1 and 10000 in 16 minutes. Same algorithm in Python on a MacBook: 0.04 seconds. Rust: 0.002 seconds. What are you doing with this power? Nothing. Lame.

This satellite tracker is very cool. You have to hand enter the TLE data which isn’t a big deal. It’s in BASIC though so just oh so slow ;-) #commodore #c64 #hamradio
