Hello.I'm new to the forum and I'm looking for a copy of the schematic to build a Solid State Oscilloscope from the Forrest Mimms' "Engineers Notebook" that Radio Shack used to sell in the 70's.I believe the scope is based around the LM3914 driver with a 10x10 matrix of LEDs. I found my old project of the scope that I had built back in the 70's while looking through an old junk box and I know it used to work but is missing an IC and has some broken wiring.
