One manual was for RCA's CDP18S020 evaluation board, manual MPM-203 'Evaluation Kit Manual for the RCA CDP1802 COSMAC Microprocessor', dated Sept 1976. (The version MPM-203A does NOT have a hex dump.) A number of copies of MPM-203 are available on Web archives.

I posted a message on a Microsoft community forum, and got back a reply saying to try turning off some of the Windows Services such as Superfetch. I tried this and discovered there are some services which slow the 1802sim down significantly. This is weird given that the CPU is showing almost no activity (98%+ idle time) in Task Manager - which in itself warrants further investigation. What made the difference for me was 'Tablet PC' Service in Win 7 and 'Touch Keyboard and Handwriting Panel Service' in Windows 10. You can also wring more speed out by turning off Windows Search service, but that slows down things like searches for apps and Control Panel items etc.. I've now gotten the Windows 10 Toshiba Kira into sub-second territory like the older Win 7 machines. I also set it up to dual-boot into Win 7. Win7 is still slightly faster than Win 10. WPF is still unbearably slow compared to WinForms.
The RCA CDP1802 COSMAC microprocessor is a one-chip CMOS 8-bitregister-oriented central processing unit introduced in 1976.

Although the 1802 is now more than 30 years old, it continues toprove itself in many industrial and commercial applications.A persistent rumor identifies it as the furthest microprocessor from Earth, havingbeen used on board the Voyager spacecraft. (Voyager 1 is nowthe furthest human-made object from the Earth, at more than 100 A.U. distance.)Certain versions of the chip were extremely resistant to cosmic ray upset,making it well-suited for use in space. However, design work for the Voyagerand Viking series spacecraft began long before the 1802 was available;instead they used custom-engineered computers. The Galileo spacecraft, however,used several 1802 processors.

The 1802 was first popularized for hobby use in a 1976 Popular Electronicsarticle that described the 'COSMAC Elf' computer. Around thesame time commercial companies began offering similar productsbased on the 1802.

The 1802 is interesting for a number of reasons, not the leastof which is the fact that it uses static CMOS circuitry, meaningit has no minimum clock frequency. Also, most instructions executein two clock cycles. It has sixteen general purpose registers,each of which are 16 bits wide. Any of these registers can be usedas a program counter or an accumulator.

  • Ual for the CDP1802 COSMAC Microprocessor 1976.pdf 5. 2 System Design Overview 2.1 User Interfaces.
  • RCA CDP1802 – as 2013 version. Probably the first 8Bit CMOS Processor, introduced about 1976. But how would a time warp of 37 years from 1976 to 2013 affect performance? Hardware description languages like VHDL and Verilog can describe functionality for hardware for implementation into FPGA and ASIC.
