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.

- Finally got me some real (r@re) punched paper tape. Actually have no idea what’s on these so I’m gonna have to break out the worlds worst paper tape reader to give it a go.
- Lived here 10 years and gone for a walk 4-5 times a week (including winter). So I’ve probably come over this hill 2000+ times. Still not tired of the view around here. Happy Saturday.
- Wow this book arrived crazy fast. Guess the Apple IIe is the vintage machine I’m keeping on my desk for July.
- I need an ESP32 that's like an Arduino Mega. Can I have like 60 usable GPIOs please? Sigh.
- I'm a decent 6502 assembly programmer (milage may vary) so I figured hopping onto an assembler on the Apple II would be a snap. It is... except I never learned ProDOS... got hung up there. Much reading and now I'm comfortable. #appleiie
- Taking a break from a VMWare certification to have a little Apple IIe fun. I don't have a color monitor (my Apple monitor is Green) so to get color I HAVE to use my capture setup. Works pretty well ;-)
- Wait, everyone didn’t save their Trapper? I’m the only one? Huh.
- Designing composite video in FPGA for the 6560/1 VIC replacement project #vicsrevenge... this might be the most useful visualizer/synthesis tool I've ever seen. Load your Verilog and get a visual representation AND what amounts to a test bench setup. Brilliant! #FPGA #commodore
- Today's side quest is to get back into computer vision. Might was well kit-bash it with reading paper tape right?
- A year later and I finally soldered the keyboard header pins in. Coming soon :) #commodore
- I blame the influence of @K0FFY_Radio for this purchase
- I need the 80 column mode on my 128 for a long number project this week. July is my scheduled maintenance month for this machine so I might as well do that first since I have it out. No retrobrighting happens in my shop. This thing earned it's yellow ;-) #commodore
- JiffyDOS on a VIC-20 is a strange animal
- I forgot that I have this butane powered soldering iron. Very convenient for a single quick job. Gotta keep it in mind.
- A little more speed from the 6502 · imapenguin
- eBay, have you lost your mind? Literally no one should be interested in this.
- I needed some window tint for the overhead window in the airplane, and it’s just a bonus that it is just the thing you need on a KIM-1 (clone) to increase the visibility of the LED display. Before and after is pretty stark. #commodore #kim1
- Pulled out the FabGL board. Apparently I was running Windows 3.0 last time. Seemed more fitting to turn it into a VIC-20. And what’s the first game on the list in the distribution? Splatform by @8BitShowAndTell… That guy sure gets around #commodore
- Squeezing @BrunoLevy01's RISC-V core onto an Icestick #FPGA is a lesson in "you really can do a lot with just a little". So many lessons to be learned. At 50Mhz Pi and Mandelbrot work really well. I'll leave the Icestick permanently hung off of this Raspberry Pi from now on.
- This is the best cure for writers block that I know of. There are no shortcuts.
