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.

- Working on the Snappy this morning for @adrianglz64</a> , why do I like this weird character thing while flashing it? Also, my capture device does an excellent job picking up the jail bars on this particular machine ;-)
- Fits in the case. Monitor and TheC64 are 5V. Both run off of a single split wall plug or a 10Ah battery. Need to design/3D print brackets(less foam please) and buy a right-angle HDMI connector. I can visit @gregnacu and his Ultimate portable in a cafe soon #commodore #c64
- I've been trying to figure out what to do with my "TheC64". I have this pelican 1490 case and a 14" very thin monitor that will fit in the lid. I need some kind of mechanism to raise it up when it's open. Hmmm... #commodore #c64
- For the first time in weeks I don't know what to make next. Blinking cursor is taunting me... #commodore #c64

- Been avoiding this for some time.
- Finally got this 128 sorted out. 4.95 volts on the board is WAAY better than the 4.61 when I started.

- More C64 Badlines fun while on Zoom calls. Running @NoelsRetroLab benchmark with the screen on vs screen off (PAL). 2.4 seconds faster.
- In High school (like 1991) my grandma bought me a bunch of electronics equipment from Radio Shack. I’ve upgraded almost everything over the years except my multimeter which finally went to multimeter heaven last week. Its replacement lacks the vintage charm though.Thanks grandma

- 10 minute lunchtime progress: Even if I set the CPU speed on the Ultimate to 48MHz it looks like the Part 5 cipher calculations will still take 190 hours to complete. Or... 380 days on a standard Commodore 64. I may have to rethink this one a little... #commodore #c64
- c0pperdragon verdict · imapenguin
- The c0pperdragon ended up in the short board 64C. The installation was easy other than the momentary panic that I had bent a VIC pin(I didn’t).
- I bought one of these but have two machines that can really benefit from it. Thus begins the internal dialog about which one. Shut up, I’m not talking to myself. #commodore #c64 #128

- Only have time for so much. In addition to my code cracking work, I have time for one hardware project this week. These are my choices and I want to be all in on all of them. #commodore #fpga #6502
