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.

- Well I was shooting for completing it in a week. Or less than 24 hours. One of those. Works great @futurewas8bit #commodore
- Still need to do the case and the key caps but I couldn’t resist trying a first boot of the MiniPET 40/80. So great. #commodore
- This would be fine.
- I made a clean spot. Sigh, now I’m going to have to do the whole thing.
- It’s MiniPET 40/80 day. The first 10 are numbered and I have number 3! Pretty neat. These switches are gonna take quite a while to assemble and solder. As usual, fantastic packaging by @futurewas8bit I’ve been looking forward to assembling this for quite a while. #commodore
- Today’s “learn something new every day” is pretty challenging.
- Delivery from @FW4511 in the UK today. Thanks!
- Just trying out my dual video capture. Might as well have a couple of them race. Atari 400 vs VIC-20 same program. Curious that the Atari has the same processor clocked higher but is slower in this version of BASIC. It sure was harder to type on versus the VIC. #commodore #Atari
- SVideo out on the Atari 400. Have to hold the cartridge port switch down when it’s out of the case to get it to boot but it’s working. #atari
- Finally have a reason to use my iPad.
- 10 minute lunchbreak progress: Porting an old PET maze routine to the VIC-20 and Atari 400 for a project (also just for science).
- VickyTwenty ended up being two things: The unsoldered pin on the character rom that was only making contact sometimes, and it turns out that the socket under the VIC was cracked. Not in love with these precision sockets, many chips fit loose. May have to change brands
- Switching gears. My first dive into a 400.
- Unity…
- Troubleshooting a VIC-20 with a strange color memory issue. Is working other than this. I've swapped all 5 RAM chips.

- This is the first "real" video out of my VickyTwenty. I used a video mod board to get S-Video out on it.
- Parts order from retro8bitshop came today for my 250407 replica. I may start this one next depending on if/when the MiniPET 40/80 ever ships.
