Dave, I understand your point and your fine sense of humor . But allow me to justify my options. 1. My flash box cable genesis: Easy to build it isn't for sure, if someone expects a step-by-step instruction guide that anyone with minimum skills can just follow and get a working product in the end. But my flash box cable project is documented well enough to allow a skilled person to build their own cable by adding their own ideas. I believe that is the whole concept here. DIY! I decided to share my findings because I couldn't find anyone doing what I had to conceive and build: I needed visual feedback and proper press buttons to make the flashing as practical as possible. 2. What's the hard way? The harder way was to build a cable based on the legacy RS232 serial cable, and then fight to find a serial port on a PC to connect such cable, or even worse, add a USB to RS232 converter, when we have these IC's around that are doing this work for us: Take any common PC USB port, plugin the serial adapter and voila, you have a TTL serial interface ready to connect to your HP-20B/30B! 3. And is there a even easier way? Of course there is always the simplest solution of all: Buying a ready made cable... Oh, wait, the only problem is, as far as I can tell, so far nobody was able to offer such a product. Jose Mesquita RadioMuseum.org member |
