I write about the past, present, and future of technology across three sites. imapenguin.com explores retro computing and programming fundamentals, milkcrunch.com covers modern software development and engineering culture, and evadot.com examines commercial spaceflight and the new space movement.

RSS- I wonder where in my yard I should be looking for this package…
- Think I found the color film I’m adding to all of my 7 segment displays to help them show up better on phone cameras
- I own a couple dozen calculators. I checked and only two of them can multiply two 32-bit numbers and give me the full 64-bit product. The@NumWorks and TI Inspire. Oh, and a Commodore 64 if you can code in Assembly;-) #commodore

- Always meant to read this series. Found em for a dollar so no time like the present.
- Vicky-20 S Video Mod Results · imapenguin
- Finally got around to doing the S-Video Mod on my Vicky-20. The results are pretty good. Probably about as good as you can get from a VIC-20 of any kind, so certainly nothing to complain about there. #commodore
- Had some fun last night playing with SYS parameters and learning a lot. Here's extending BASIC to implement a PRINT AT equivalent on Commodore 64/VIC-20 to do the 100 Door problem. Again ;-)
- Yet another version of the 100 door problem; this time, let's extend Commodore BASIC to add PRINT @ · imapenguin
- Writing an article and occurred to me I need to add a word to my Mac dictionary... #commodore
- Picked up a set of gymnastics rings to add to my workout setup at home. I do enjoy these “users instruction enjoyment and importance” lost in translation comic books they included. These tapes are kindly prepared…
- Next to the Corsham KIM-1 the KIM Uno looks crazy tiny (it is). I heard from questionable sources that it’s more about how you use it than the size so don’t worry little KIM Uno, it’ll all work out. #commodore
- I built a paper tape reader from scratch without any reference designs. Someone pointed out there there’s a book from 1979 that has designs for this in it. Annndd I happen to own this book…. Sigh. Let’s tell people I wanted to do it the hard way on purpose shall we?
- Alright, going outside for the rest of the day but I promised myself I'd go from novice to expert(ish) in @JuliaLanguage in 2022 so I needed a project I want to work on. Implementing a 6502 emulator seemed pretty natural to get started ;-)
- Success! The world's worst paper tape reader: Decoding on the PAL-1(KIM-1 Clone), LEDs (because blinkenlights) AND VIC-20 at the same time!
- Success! The world's worst paper tape reader: Decoding on the PAL-1(KIM-1 Clone), LEDs (because blinkenlights) AND VIC-20 at the same time! Timing is tricky by hand, but I couldn't be happier with this complete hack job that actually works. Are YOU keeping up with the #commodore?
- Worlds worst paper tape reader mid week progress: Test creating the enclosure peices. Not thrilled with the PVC as a material. Might move to ABS or maybe even a hardwood, but this cheaply confirms my design looks good. Happy camper.
- Being inside today seems like a silly thing to be doing.
- Well that's pretty satisfying. Happy Wednesday from my PAL-1 (KIM-1 Clone)!
- Worlds worst paper tape reader progress: this is just as good as drawing schematics right?
