Re: 8301

I was looking into the idea of using on board RAM in an FPGA, but even with the basic QL display resolution, the amount of block ram you need means using quite a large FPGA in relative terms. And if you want higher resolutions, it just ramps up. Thinking about the way the video is produced in the 83...

Re: Need electronic expert advice for a project

This makes more sense now on the switch side of things. The switch enable will trigger that lower of the 3 comparator's (there are 4 in the 339 package), and that in turn will switch Q6 on, allowing the SW pin to rise towards +12V, it would normally be dragged to 0.6V by the bias resistor to -12V a...
