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.

- Assembly coder friends will appreciate this
- You don't HAVE to "create a video for this."
- Today’s lunchtime learn something new is sorting out all of the Rockwell AIM 65 monitor commands. The built in assembler is pretty good. Happy Wednesday!
- I loved the poem by @K0FFY_Radio so much that I framed it and hung it in my office.
- Finally found breadboard IDC connectors that actually stay in breadboards
- I've loved fixing things as long as I can remember. Instead of a lunch break, I'm fixing two keyboards. Not just any keyboards, the BEST keyboards. Happy Monday!
- Needed a quick second logic analyzer for a slow circuit. It’s a hack but it works :)
- 10 years ago today I witnessed a hit and run which resulted in an elderly couple being stuck in their car which caught fire. Manager at the restaurant across the street was pretty upset when I stole their fire extinguisher to put the fire out. I guess that Navy DC training stuck.
- My "Complete Lance A. Leventhal" library is one more book closer to completion
- When you get a new to me breadbin Commodore 64 (the best computer ever made) from @K0FFY_Radio you get dot matrix letters AND an unexpected software bonus. Woot!
- Taking the printer interface on the AIM 65 clone for a test drive. A sine wave should do the trick
- I don’t have diabetes, but I’m a health data nerd. For the next 14 days I’m wearing a Freestyle Libre CGM. They say it takes a bit be accurate. Let’s hope that’s true because compared to a finger prick meter (which is pretty accurate) it’s not even close.
- I’m on the prowl for this book. Physical or scanned electronic. There’s a copy on Archive.org but it’s not downloadable. Check your attics and basements
- Package arrived from Japan today. I’m super excited to be a small part of this project. AIM-65 clone for the win!
- Writing mirrors thought. Outsourcing it to AI may sideline our cognitive engagement. I value AI's potential yet value intellectual growth for people. Use AI to help cure cancer (or MS), but do not stop thinking and creating. Also, quit being lazy; it makes you boring.
- I found a tube with 8 old school 6551’s in it. I’m running the 6502 cluster nodes at 1.843Mhz so I needed the “AP” model which is what I have. Sooo much easier when you’re trying to multiplex 5 serial devices to not have that transmit bug and delay math in the newer model. Woot!
- Pretty sure everyone has a serial tap these days
- Ooooo nice, a 6551 without that nasty hardware bug. Fancy.
- Building a software serial bridge · imapenguin
- Still lots of work to do on the job scheduling and "worker node" software side for sure, but my 6502 Cubesat sized "cluster" is up and running on a VIC-20 controller node. Not a bad cap to the week. Happy Friday!
