This is quite random but this is the only place I thought may have someone with the answer. I found a box of Chips in my wife's grandfathers house (he passed away many years go). Doing a little research the chips are from a Heathkit based on the part numbers. Heathkit sold kits to build of things like ham radios, clocks, and other home electronics may year ago. My guess is these are from the mid to late 70s. However only having the chips it is hard to know what project the chips were slated for. Below is the list of chips and a description I could find online. Does anyone have an idea as to what type of electronic component these would be used to build? It would be really interesting to know what he was trying to build.
