I can currently do 10 clean pullups in a row. My august goal is to get to 20, which is not easy for me. Many years ago, my cousin used to say, “my legs are bendy,” when he was tired and didn’t want to walk anymore. Well… my arms are bendy now.
As a long time Commodore guy, I’ve under appreciated the Apple 8Bit computers. Really quite amazing for the early 80s. This took just over 3 hours. Happy Friday!
Still testing the timing with the W65C02S-14 running on this VIC-20. Super expander cart seems to be fine and it can do math well enough. 90 minutes to complete this isn’t bad for 1981. #commodore
Giving the Julia Language another go for a new project. Lot’s to love about it…
The VIC-20 palette voltages are kinda tricky. For this alpha version of the project I’m just going to have to be okay with this particular background blue for now. Funny, if you pick up 470 ohm resistors out of the box instead of 270 how much trouble you can make :) #commodore
Probably only funny to me… I was working out some resistor ladders for the VIC replacement project and got two values wrong. Think anyone would mind #commodore 64 colors on their VIC-20? Happy Wednesday!
I wonder if there’s any value in writing a VIC chip and 6502 protocol decoder. Hmmm #commodore
New stretch goal: get the most accurate pixel timings on VIC-20s possible with equipment I already have. We’ll have to resort to… dun dun dun… math! #commodore
Before day job two steps back on the VIC replacement project: since PAL was progressing nicely I switched to NTSC to catch up but broke something along the way. Hmm… that isn’t right AT ALL #commodore
