Hi Just digging through my scrap box a while ago, I came across an IC socketed next to a 7 seg LED display on an old bit of veroboard. The markings are all faded badly. I'm assuming it is some sort of BCD to 7 seg driver or something similar. The marking could be: DM74S238 or something similar. Any ideas??
