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.
These expansions are available at the same price as the previous ones, $29.95 with FREE Shipping. They can be ordered from the MCS-80 Expansion page.
