Hello, I have a bunch of the venerable 1802 CPU, Don't know what to do with them. If I remember correctly, they are still occasionally used because they can take a bit more of hard radiation than other CPUs. I have roughly ten each of 1802, 1851, 1852, 1854, 1855, 1861, 1864, 4034. I could trade them for something little in the PIC or Atmel line, or, at your suggestion, throw them in the dustbin.
