Intel system development kit

Each time Intel launched a new microprocessor, they simultaneously provided a system development kit (SDK) allowing engineers, university students, and others to familiarise themselves with the new processor's concepts and features. The SDK single-board computers allowed the user to enter object code from a keyboard or upload it through a communication port, and then test run the code. The SDK boards provided a system monitor ROM to operate the keyboard and other interfaces. Kits varied in their specific features but generally offered optional memory and interface configurations, a serial terminal link, audio cassette storage, and EPROM program memory. Intel's Intellec development system could download code to the SDK boards.

In addition, Intel sold a range of larger-scale development systems which ran their proprietary operating systems and hosted development tools – assemblers and later compilers – targeting their processors. These included the Microcomputer Development System (MDS), Personal Development System (PDS), In-Circuit Emulators (ICE), device programmers and so on. Most of these were rendered obsolete when the IBM PC became a de facto standard, and by other standardised technologies such as JTAG.

The SIM4-01 prototyping board holds a complete MCS-4 micro computer set including the first microprocessor, the Intel 4004, introduced in 1971.

The SIM8-01 prototyping board based on the Intel 8008 was released in 1972.

This was Intel’s first 8-bit Microprocessor based development system. This board contains the CPU, RAM, ROM, and TTY terminal interface all on-board and can hence run as a single board. It features 1K byte of RAM in 32 chips and 2K bytes of EPROM in eight chips.

A PROM programmer board was available (the MP7-0x) and connected via a Micro Computer Connector Board (the MCB-810).

Although not marketed as such, the SIM8-01 represents the first 8-bit microprocessor based Single Board Computer (SBC) available as early as April 1972, priced at $900 ($2,850 in 2022).

The 8080 System Design Kit (SDK-80) of 1975 provided a training and prototype vehicle for evaluation of the Intel 8080 microcomputer system (MCS-80), clocked at 2.048 MHz. (The basic 8080 instruction cycle time was 1.95 μs, which was four clock cycles.) The SDK-80 allowed interface to an existing application or custom interface development. A monitor ROM was provided.
