Overview collection of processors and support chips

Processors From 1970 I have been working as lead engineer of a R&D department for many years and I have designed a lot of equipment as embedded programmer and hardware designer and I programmed a lot of different microprocessors at work but also at home. I collect old computer chips like processors, pio chips, pia chips, sio and uasrt chip, but also sound and video chips and old eproms and ram chips. Sometimes it is very hard to get an old microprocessor and other old computer chips but sometimes you can still buy them. I also get some old microprocessors and old computer support chips from disassembling old computer boards. I have one page that contains the whole collection by year and some more Information about every chip, Wikipedia pages and Datasheets, this page is a reference by family and type, my wish list and trade list, and some information of the different suppliers and databooks, catalogs and reference manuals. If the number of chips in the last column is more than one, I can trade. This is the detail page of my collection. Kind regards, Hein Pragt.

I also have a Facebook Group on Retro Computing and Electronics, feel frtee to join!

Collection of processors and support chips by family

Here yoiu can find an overview of alle the processors and support chips in my collection ordered by type and family.

Zilog and clones / second source chips

Zilog started with the creation of the Z80 processor in 1975 and that story is also amazing to read. The chip was officially introduced on the market in July 1976. I used the Z80 a lot and I have worked as a C and Assembler programmer / hardware designer on Z80 systems for many years. Then I had to switch to other processors and microcontrollers, but I am interested in de Z8 and Z180 chips as well. I also have some DDR clones of Zilog processors.

6502 family chips

In 1975 MOS Technology introduced the 6502 processor, the design team had formerly worked at Motorola on the 6800 project and the 6502 is essentially a simplified, less expensive and faster version of that design. A lot of video game consoles and computers, such as the Atari computers, Apple II, NES, Commodore 64, BBC Micro used the 6502. I never liked the processor because the lack of I/O and an 256 bytes stack. But as it became very successful I learned a little about the chip family and I liked the systems that were built with this chip. It is an interesting chip family to collect.

6800 family chips

In 1974 Motorola introduced the 6800 microprocessor designed and it was part of a complete chip family with several versions and a lot of peripheral chips. I knew the design but did not use these chips until 1998 when I worked for a company that made embedded systems using the 6809 processor. I modified a lot of assembly code for these machines and I really liked the processor. Because the 6800 family is very big, it is interesting to collect them.

68000 family chips

In 1979 Motorola introduced the 68000 processor and the design implements a 32-bit instruction set, with 32-bit registers and a 16-bit internal data bus. The address bus is 24 bits and does not use memory segmentation, which made it easier to program for. But it was a huge chip with a lot of pins and to complected and expensive for hobbyist. It was widely used in more expensive computers like the Apple Macintosh, Commodore Amiga, Atari ST and also the Mega Drive console. I never used it as a programmer or designer, but the chips are impressive and nice collectors’ items.

Intel families and clones / second source chips

Intel (integrated and electronics) was founded in 1968, and they created the first real microprocessor chip, the Intel 4004. After that the 8008 and de 8080 and a huge processor family followed including the MSC-48 and MSC-51 family of microcontrollers. When I started working I used 8080 based CP/M machines but I never programmed the 8080 in real, I used the Z80 from Zilog. But with the first PC I learned to program in ‘C’ and Assembler for the 8088 and the 8086 processor and in embedded systems I programed a lot for the Intel 8052 microcontroller. When demands in the hardware grew we switched to a Intel 80188 processor. I also wrote a lot of ‘C’ and Assembly code for this processor. I am interested in Intel chips up to the year 2000.

PIC processor chips

I never used PIC microcontrollers until a few years ago, I always thought they were too limited for the things I wanted to create. I worked with companies that used them in 1998 but I kept away from the PIC processors. A few years ago I learned that these chips were very nice to emulate other chips so I got interested and created one design with a PIC chip. The family is very big and I collect these chips and I prefer the real old ones.

4 bit processor chips

Four bit processor chips are interesting, I never used them and I have a few in my collection. When I have more time I intend to build small systems on a breadboard if possible. Most of these chips have a very interesting design and use.

Special processor chips

Most of these chips I have heard of but I never got to use them. But they are interesting to get to know and when I read the datasheets, some of them are quite impressive. I have used some of them in computers I worked with, like the Spark processor that I used when I was working on Sun Solaris systems. This is a separate box in my collection.

Video chips

I do not only collect processor chips, I like to have as much old chips that made up al the old retro computers as possible. And video chips were part of that, some of these chips became as famous as the microprocessor chips at that time. I have programmed the Video chip of the MSX-1 and MSX-2 computer a lot, enabling graphic features and I even wrote a ram-disk driver that used the extra video ram of the MSX-2 for data storage. It is nice to see how these chips have grown to their current power.

Sound chips

I also collect sound chips that were used in Microcomputers in the last century. Sound chips have grown from simple beeps and with noise, to complete synthesizer systems and it is nice to collect these chips as well.

peripheral chips

I also collect peripheral chips, a peripheral chip is commonly a chip used to put information into and get information out of a computer. They are part of the computer but they are not the core components of the computer, such as the CPU of memory. There are a lot of peripheral chips and a lot of types like serial, parallel interfaces, memory and network controllers and sometimes they are universal and sometimes they were specially made for a certain processor family. I keep them separate from the processor families, but arrange them according to type and their family, if possible. Some peripheral chips are specifically made for one computer system like the VIC and TED chips of Commodore and the ULA of several other systems. I collect these as well.

Wish list of vintage chips

Look at my wish- and tradelist that I have on a seperate page.

Documentation pfd files

Sometimes it is hard to find information about a chip, certainly the old ones. To know what year a chip was introduced and what family it blongs to it is noce to have soms old datasheet and catalog books as a reference. I have some and I put the to download here.
