Looking for an upgrade for your Atari or Amiga? The CPU Shack now has..CPU’s for sales. Tested working, genuine full featured (FPU + MMU ) XC68060RC50A Rev 5 CPUs.

Tested using a Blizzard PPC accelerator board at 50MHz clock. A few CPUs were checked using TF1260 board @66MHz, worked well, but I won’t guarantee they all like 66MHz (though with cooling they should hit that and likely more) All CPUs were checked by booting into DiagROM, checking CPU Revision there and then booting to AmigaOS 3.1.4 (Caches/FPU enabled).

These are $289 with FREE Worldwide shipping.

The CPU Shack Museum is proud to announce the availability of The Collector’s guide to Vintage Intel Microchips, written by George Phillips Jr. This e-book (PDF) contains over 1300 pages, and 900 photographs of Intel Microchips from the 1960’s and 70’s along with their functions, package variations, rarity, and valuations.  Everything from the 3101 Static RAM to the i4004 4-bit processor. The author, George Phillips, has moved this book into public domain.  Originally published back in 2007 it is still a very useful resource.  Being 10 years old, some of the values are inaccurate and there has been a few more Intel chip types from the 1970’s found since then, as well as some different package/marking variations.  However the Guide is really an important resource for any collection that includes Intel IC’s from the 1970’s.

I have been collecting information for an update to it for some time, so if you have any Intel chips/variations not in this guide, feel free to let me know.

You can download The Collector’s Guide to Vintage Intel Microchips here (pdf 22.9MB)

3002 Test Board

We have released a simple (its our least expensive board yet) Test Board for the Intel 3002 Bit-Slice Processor.  The Intel 3000 bit-slice processor family was introduced in 1973 and were made on a  Schottky Bipolar process. The 3002 series was also second sourced by Signetics, Siemens, and Intersil, and clones were made by the USSR and Tesla  (Czech).  The 3002 CPE is a 2-bit ALU and register file that can perform logical and arithmetic operations, left/right shifting and bit/zero value testing. The 3002 also includes 11 registers (R0-R9, T), an accumulator and a Memory Address Register (MAR). The 3002 CPE elements execute micro instructions generated by the 3001 Microprogram Controller Unit (MCU) based on micro code stored in PROM.
Its only $69.95 (including FREE shipping worldwide)

Order it on the 3002 test Board page.

In other related news, we are also developing a test board for some other BSP. Hopefully we’ll have a single board (with expansions) that can handle AMD 2901/03/203 and MMI 6701 processors

6801/6803 Expansion Board and PCP

After several months of development an expansion for the 680x/650x Test system is now available to support the very popular and widely used 6801 and 6803 MCUs.  The Motorola 6801 was one of the first (with the 6802) MCU’s that Motorola made based on the MC6800 8-bit processor.  It includes RAM/ROM, Serial I/O and timers.  The test board tests the function of the base CPU, the timers/data capture, and the Serial I/O.  The MC6803 is a 6801 without the built-in ROM and with less I/O.

The expansion supports both types as well as their copies/derivatives made by Hitachi, Fujitsu, SGS and others.  The expansion is included in the complete 680x/650x Test system, bringing its total supported processors to well over 35.  The expansion does require updated firmware, which is included in all new systems (and available to upgrade previously sold systems.)

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…

Coming Soon!

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.
