question re HP 264x terminals

  I took the CPU card out of one of my HP 2648s and it also has an AMD part
with a HP part number (1820-1701). I had guessed that it was a 8080. I took
some pictures of the card and CPU but I borrowed someone else's camera and
the pictures were LOUSY. IIRC the name on the card was simply "Processor"
or maybe "CPU" with nothing to indicate what kind of CPU it was. I'll
bring the card home next time and try to get some decent pictures.

  There's also a HP 2647 at the warehouse. IIRC There's no drives of any
type on it. I'll try to open it up and see what kind of CPU is in it.
