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- Running the 8 Bit Show and Tell VIC-20 Super Expander Programming Challenge on the Commodore 64 · imapenguin
- Working on the Retro pinout project a little at a time. 128 pins captured and about 4500 to go. Thanks to all who have offered to help so far.
- The retro pinout project · imapenguin
- My new open source project: Collecting scope outputs on every IC on retro computer boards. I'll need lots of help from the community
- I went right to getting the VIC working yesterday and am just now getting to the bucket of other stuff @TheGavNinja sent me. Lots to check out #commodore
- These are the chips getting the dreaded X on them just from this evening. Sheesh
- Brought another vintage computer back to life from the trash bin. Some probing around with the oscilloscope narrowed it down to a bad VIC chip. Desoldered, installed a socket and replaced it and it’s back in service.
- The first spreadsheet I ever used was Practicalc. Seems appropriate to use it to hold a BOM for a new retro board build
- Sunday morning Enigma work. Because reasons… #commodore #crypto

- Six years ago today I became a licensed pilot ;-)
- Just reading this book for the first time. It’s really good. Seems like a possible candidate for an @8BitShowAndTell book club.
- Making and breaking Ciphers on the Commodore 64 Part 12 – Pontifex – Solitaire from Cryptonomicon · imapenguin
- Did you know that Bruce Schneier created a cipher for Neal Stephenson in Cryptonomicon(1999)? Uses a simple deck of cards, so naturally…Commodore 64! Should actually work on most 8 bit machines of the era with slight mods.
- I guess I shouldn't be surprised, but 3583 bytes on an unexpanded VIC-20 really isn't much. My Pontifex program doesn't fit ;-)

- Retro computer repair people problems… when you need an NTSC VIC and TWO PAL versions arrive first
- It freaking works. I can't believe this thing actually works. #commodore #c64 #crypto
- I think screenshots from my scope desktop software is better than a photo of the scope screen. I'm going to start with pinouts of a Longboard 64 NTSC and organize the github repo. This would be much easier with two people in person. One to probe, the other to record. #commodore
- I want to see scope pinouts of every pin on every chip on a VIC-20, C64 (long and short) and 128. If it doesn't exist, I may create this as a resource. Just power on and pin out, screenshot scope. Nothing running. #commodore
