RCA 1801 disappeared from face of Earth forever... You would be better off
to purchase at:
http://www.sunrise-ev.com/membershipcard.htm to use 1802. The 1802 was very
successful microprocessor that replaced 1801 because it required to have a
pair of chips to work together. I believe I saw 1801 was more than 30 years
ago.
Good luck!

Hi there,
I just purchased an RCA Microtutor minus the rather important CPU card. I
can recreate the card but I expect locating the 1801 chips will be
difficult. I am just posting this in various forums in case anyone has any
leads on where I might find either the complete card or the required chips
to make a replacement. I'm wondering what, if any devices were built with
the 1801 that I might be able to scrounge from.
Thanks again,
B
