Before today, I was using a “field anti-static mat” on my HP Logic Analyzer cart. This was the cart that I built from scratch, and I think it did the trick for the most part. But the more and more I started...

Graphics Primitives are working, at least mostly.

So we’ve got a frame buffer now which means we can start writing 68K routines to write graphics into it. So here I’m playing around with lines and circles. I’m using a random line drawing routine from...

I bought at Saleae Logic which is an inexpensive logic analyzer. See link here. It isn’t nearly as fast (only samples at 24mhz max), and it doesn’t have as advanced triggering capabilities, but it does do...

thinking about cross-platform support

To make this accessible to everyone, I’d really like to add support for more than just Windows. I thought that Java would be my ticket to freedom here, but that is turning sour real fast. From what I’m able...
