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.

- Happy Pi Day! Another year of 6502 machines verifying the digits. #commodore
- New to me TI-92. I did not realize just how huge these things are.
- Just looking over the Minnesota fishing regulations. I feel like I've missed a memo.
- If I view this Commodore PET picture on a C64, does that break the space-time continuum? The picture itself represents the very moment computing peaked. Long slide into mediocre since then. Happy Friday!

- The PET Diagnostic boards designed by Sven Peterson arrived and I just realized I have the BOM loaded in a shopping cart but never actually pressed “submit order”. This is what happens when you have too many simultaneous projects.
- Back in the saddle on the VIC chip replacement. Today I’m implementing the internal registers. Nice (but slow) progress. I’ve decided not to bother with implementing interlacing on the first version. #commodore #vic20 #vicsrevenge
- Everyone prints their MOS component datasheets and binds them right?
- My arms might work again on Tuesday.
- Anyone else have several VIC-20s with test clips more or less permanently attached? No? Just me. Okay then.
- Happy Friday. Time for some Blinkenlights! Here's a couple of LED patterns on the VIC-20 and PAL-1 (KIM-1) clone.

- VIC Chip "drop in" replacement work this evening and got distracted. Why make a simple drawing in your notebook when you can have a VIC-20 do it? Back off, man; I'm a scientist.
- Finally got around to assembling the PAL-1 gadgets. Can an office have TOO MANY blinkenlights? I don’t think so. Might use this with my “worlds worst paper tape reader” setup.
- Happy Tuesday. You don’t have to be angry on the internet today. Just do cool stuff and share it. Repeat.
- This has gotten a little out of hand.
- I've had the Numworks calculator for a couple years now. I find myself reaching for it more often lately. The base conversions are easy to access, and it sure is fast.
- A coworker had this GIANT flag made for me. So great.
- I need to wait to do the final touches until Oscar sends me the correct LED bracket but it went together nicely. Happy Friday !
