The CPU Shack is pleased to now offer test systems for testing the famous Intel 8086 and 8088 processors. They also support testing of the 8087 FPU, as well as the NEC variants (V20/V30). As an added bonus, an expansion is included for testing the i186/i188 processors as well.
Of course the original NMOS, and later CMOS versions are supported from many manufacturers.
Head on over to the MCS-86 Test System page for more information and to order your system.

Continuing our goal of having test boards available for pretty much every common architecture of the 1970’s we now have a board available for testing Signetics (and later Philips) 8-bit NMOS processor, the 2650, 2650A and 2650B. Made on a cool black PCB they are a fairly simple system, but are capable of testing some of the special features of the 2650 as well as the added features of the 2650B (if anyone happens to locate one)
These chips did not achieve the wide microcomputer success hoped for (likely due to a lack of second sourcing) they did find their way into many industrial/embedding systems, as well as many arcade/video games (including some made by ATARI).
These boards are in stock, and ship world wide for $94.95. Head on over to the 2650 page to grab one.

National Semi SC/MP Test Board
National Semiconductor released the SC/MP (aka the SCAMP or ISP-8A-500) in 1974 as a low cost PMOS 8-bit processor. Later the design was moved to an NMOS process resulting in higher clock speeds and simpler power supply requirements. This version was known as the SC/MP II or the ISP-8A-600. It was used well into the 1980’s.
This test board is designed to test with the PMOS or the NMOS versions of this chip. It has power supplies and clocking for both the PMOS and NMOS versions and requires only the slide of a switch to change between them.
I have a couple in stock, $94.95 with FREE shipping.
More info and purchasing info on the SC/MP Test Board page.

I finally got more of the Intel MCS-4/40 Test Boards ready to ship. Grab yours soon if you want one. All other test boards are in stock too, including the RCA COSMAC boards, the Intel MCS-8 board and the Intel MCS-80 board (with Z80 8085 and NSC800 Expansions.
New Test Boards: Coming soon will be two new test board types. First is a board for the SC/MP and SC/MP II CPUs made by National Semiconductor. The second is a whole test system, designed to test Motorola 680x processors as well as MOS 650x processors and many of their derivatives. All told it’ll test over 30 different chip types! Even some of the more unusual/special versions. Commodore 6510? Yup! Nintendo Ricoh? Yup! and a whole lot more…

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.
NSC800 Expansion Board
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.

The CPU Shack Museum is pleased to announce the availability of Test Board Systems for the Intel 8008 Processor. This system will allow you to test, as well as design program for, the Intel 8008 8-bit processor as well as its several 2nd sources, including the Siemens SAB8008, the Microsystem International MF8008 and the unlicensed East German MME U808D.
The Test System is loosely based on the 1973 MARK 8 computer, one of the very first computers to use the 8008, which was arguably the worlds first 8-bit processor.
The Boards are available here for $149 with FREE Shipping Worldwide.

MCS-4 Test Boards
The MCS-4/40 Test boards are now back in stock and shipping this week. Only have a few available so head on over to the MCS-4 page to order yours.
I also added a PDF of the boards schematic to make interfacing to it easier for any projects you may have in mind.
If you do have a project in mind, or already made one, post about it in the comments, we’d love to see/hear about it.

Z80 Expansion Board
Now available at The CPU Shack are the Z80 and i8085 Expansion boards for the MCS-80 test boards. The i8085 and Z80 expansion tools allow the MCS-80 test-board to test the function of Intel 8085 (and compatible) or Z80 (and compatible) CPUs. The test tools are connected via the ZIF socket for the i8080 CPU and into the 3×16 pin header connectors of the MCS-80 test-board. There is no need to modify or replace anything on MCS-80 test-board.
This is possible because both the Z80 and i8085 CPUs are based on the Intel 8080 processor. The 8085 is nearly the same as the 8080 from a software point of view, Intel just greatly simplified the hardware required to support it.
They are currently available for $29.95 each shipped.

MCS-4 Test Boards
The CPU Shack is excited to now offer MCS-4 test boards for sale and shipping now. These boards are intended to test Intel 4004 and 4040 processors as well as 4002 RAMs. They can also test National Semiconductor 4004s and 4002s.
Each board runs off of a min-USB connector making it very easy to use. The processors are inserted into easy to use ZIF sockets making testing many different CPUs a snap. I
