Ironically, my back has been extra sore lately. I was late for work this morning because I didn't get much sleep last night due to the back pain. About to try again...

That's the one, you found it. I spent a couple hours searching your's, and ZappMan's, sites for that. Thanks.

It was the pain in my back that made me miss it - that's my story, and I'm sticking with it. My back is better tonight, but still very painful. Hopefully it gets better overnight, I've been on prescription pain killers (Lidocain) all day, and I'll be taking some prescription pills before bed tonight.

Quote from: granz on Jan 16, 2026, 11:30 AMThis reminds me of the picture that I saw of a handheld device that, underneath the battery, had "404 Battery not found" printed in the silkscreen layer of the PCB. If the battery is installed, the printing is hidden, but if the battery cells are missing, then that label shows through the semi-transparent plastic case of the product. I can't believe that I cannot find the picture - I was certain that I had posted it to here, or ZappMan's forum.

I just happened to be sitting at my computer this morning, when an alert came in. It popped up on my screen, saying that I had gotten a response to one of my posts. I guess that it is working now, I just have to be actively working on my computer. Thanks.

That sounds like it might be useful.

Did you get finished making the CardIAC system, and working through the book?

Nice.

And posting that reminded me of this morning (severe pain in my back woke me up at 1:00, it feels like I have a knife in my back) - at just past 4:00 I looked at my bedroom clock, and said to myself "4:04, time not found."

@granz @Chris Savage
  I found some books on the ZX Spectrum, so I'll start reading those books.
