I soldered a ribbon cable to my LCD, but found it was too time-consuming having to insert those tiny wires into the breadboard. It also wasn't very portable. Then I came up with this solution: I took a strip of 0.10" spaced single header and soldered the ribon cable to t he header. I split the ribbon cable into three sections: 8-pin header for the data lines, 3-pin for the control lines, and 3-pin for the power connections. I used hot-me lt glue over the solder joints to re-inforce the cable so it can be inserted and removed quickly. This arrangement is now quite conveniently inserted and removed and makes prototyping with a breadboard less labour-intensive. After reading PIC' up the Pace and author David Benson's suggestion of makiing a n 84 on a board for experimenting, I made a PC-board with a 16C84, a 4mhz oscillator, a reset button, and an in-circuit programming header that interfaces with my PIC-1 a programmer. All the port lines and power connections are brought out to a 90-degree 0.10" header which plugs easily into a breadboard and frees up a lot of breadboa rd real-estate for the rest of the circuit. I call it the '84-Board. I have a few small breadboards that I can now have different prototypes on, and it's just a matter of reprogramming the PIC and plugging '84 board into the circuit on the breadboard I'm working on. Debug-test cycle is also much faster. Steve
