RCA CDP180x Boards Available, and National NSC800 Expansions

CDP180x Test Board

CDP180x Test Board

The CPU Shack’s list of test boards continues to grow.  Today we now have available a board for testing RCA COSMAC processors including the CDP1802 1804 1805 and 1806.  These early CMOS processors are still being made 40 years after their introduction in 1975.  Being a CMOS design, the boards are a bit simpler to make (simpler power supplies) and thus a bit less expensive.  They are in stock and shipping now for $89.95.

You can Order them on the RCA180x Test Board page.

Also available are new expansion boards for the MCS-80 boards.  In addition to the Zilog Z80 and Intel 8085 expansions, an expansion is now available for the National Semiconductor NSC800.  Introduced in 1979 this CMOS processor is a hybrid of the Z80 and i8085, taking features of both to greatly enhance the Z80 architecture.
