      Bill,

      I can help you out with the 1854.

      Actually CDP1852CE or CEX, RCA with datacodes in the range 001, 236 &
      336, new old stock, still in black foam, never taken out to my
      knowledge.

      Contact me directly for details beyond that.

      aa3nm [at} amsat.org will be fine.

      Steve

      oops. I think the memory part I had in mind was a motorola
      piece (6810?)
      and the i/o chip was an 1852.
