This is mainly a reminder for myself so I don’t forget what I did. When using Qodem in iTerm2 on my Mac along with a Microsoft Natural Ergonomic 4000 keyboard, the “Alt” key wasn’t working inside Qodem.

(Rant warning) TL;DR I gripe at how complicated it gets and offer no solutions. I really do like what Let’s Encrypt offers. Just getting there figuring out what options work and don’t work is work. I don’t know how the muggles manage it. TL;DR 2: HTTP-01 was out because of internal sites. DNS-01 was the […]

Good news! A new video RAM chip fixed the lingering video artifacts I had. I looked up the IC model that was in it “HM6116LP-2” and found some on eBay. I had to wait a couple of weeks for them to arrive from China, but popped the first one in and it worked like a […]

I finally got around to working on the TRS-80 model 4 again, specifically troubleshooting the floppy drives. Last time I tried to boot it, the drive light would come on and it didn’t sound like it was doing anything.
