How -can one light seven LED's from this, with zero having all LED's off and -seven lighting all seven of them, in bar graph fashion? How about a ROM? Just use an 82s123 PROM (or even a 2716 EPROM), feed your three bits into the low address bits, ground all the rest, and drive your LEDS (through a buffer if needed) from the data bits. /mike -- \|/ Michael L.
