Busy, busy, busy. . .

Wow, it’s been 2 months since my last confession! Yes. . .busy, busy, busy. Between work and work and work, there’s barely anytime to work. Just look at this mess on my workbench. Every time I set out to clean and organize the bench, I get caught up in a software issue or a capacitor replacement or a programming problem or the washer blowing a circuit board. Like Gilda Radner so profoundly exclaimed, “It’s always something!” And this weekend is Field Day so there won’t be much organizing soon. But I pledge that I will get this straightened out within the next 30 days or I’ll have to swear again in 30 days! Oh my!

And no! Sorry, you can’t install the update because it’s not supported by your computer’s CPU. I guess somewhere around the beginning of 2004, Intel added all this stuff to their chip: Physical Address Extension (PAE) mode, No-eXecute (NX), CMPXCHG16b support and Streaming SIMD Extensions 2 (SSE2). And the BIOS needs Data Execution Prevention (DEP), which apparently was not a stringent requirement for 64-bit Windows 8. Hard to believe a service pack would change hardware requirements for an operating system. Another strange thing is that the 32-bit version does not have the same hardware requirements, so I can...

Is Heathkit back?

So I went to a Tailgate Fest sponsored by the Cuyahoga Falls Amateur Radio Club today. I didn’t find anything I was looking for because I wasn’t looking for anything, but did see a lot of interesting stuff. The one that caught my eye was a complete Heathkit amateur radio station with transceiver, speaker, ‘scope, and tuner. It was nice and clean and functional. And boy did it bring back memories! I was a very avid Heathkit builder back in the 60’s to 80’s era….my first ham radio, my first VTVM, my first oscilloscope, and my first computer, among a whole bunch more. I loved putting those kits together, testing them and then using. But Heathkit eventually went out of business,┬áseveral times if I remember correctly. And I sold off each of those kits over the years for bigger,...
