The PCB Board itself Measures 30.5 (W) x 25.7 (D) x 1.3 (H) cm. This vintage SDK-85 computer was completely assembled back in the 1970's from the original Intel kit components and was nicely mounted in a solid wood case for use by it's builder. A 38 line parallel interface was also available. User could enter and read program results through either the buit-in keyboard/display or using a serial Teletype through the built-in serial TTY interface. The Intel 8085 microprocessor was designed for use in high-performance applications ranging from controllers to 8-bit minicomputers.Ī 2 KB monitor software stored on ROM chip provided the same commands as the SDK-86 board. The SDK-85 was a complete microcomputer system on a single PCB board including 256 to 512 bytes fo RAM memory and 2k of ROM memory, a 24 key hexadecimal keyboard, a 6 digit LED display, I/O connections and an expansion area allowing memory and I/O expansions as well as hardware experiments.The system used an Intel 8085A (5 for 'first 5 Volt microprocessor') CMOS MPU running at 3.072 M Hz. An external 5V/12V power supply unit was required to operate the SDK-85, it was not included with the SDK-85 kit. The 8085 kits usually came in component form with a printed circuit board (PCB) that required the owner to assemble and solder. In the early years of Microprocessor development, each time Intel introduced a new microprocessor (the Intel 8085 Microprocessor in this case) they would simultaneously offer a System Development Kit (SDK) allowing computer programmers & engineers a way to introduce themselves to the new processor's features and helped third part developers with hardware and software applications. It is hand-marked "A-1" on the box which is for the first version of this chip manufactured by Intel. This was a presentation award given to a select Intel employees who worked on the i386 Processor program. The 386SL was the first chip specifically made for portable computers. It added a special system management mode (SMM), in which the BIOS could more easily perform power management and other functions without requiring OS support. In October 1990, Intel released the 80386SL, which was basically an 855,000 transistor version of the 386SX processor, with cache, bus, and memory controllers, ISA compatibility and power management circuitry. The i386SL was first available at 20 MHz clock speed, with the 25 MHz model later. The extra functions and circuit implementation techniques caused this variant to have over 3 times as many transistors as the i386DX. It also contained support for an external cache of 16 to 64 kb. ![]() This processor offered several power management options, as well as different "sleep" modes to conserve battery power. It's been a wild ride the past 30 years, and whether you lived through it all or have only recently picked up your first processor, we invite you to join as we look back at not only the most popular x86 CPUs in its history, but ones you may never even have heard of.The Intel i386SL was introduced as a power efficient version for early laptop computers (Intel 386 Laptop computers first emerged as a portable computing platform in 1990). Invented by Intel in 1978, the x86 architecture has evolved through the ages, not only getting faster, but increasingly flexible as more and more extensions and instruction sets accompany each new release. We're of course referring to the longstanding x86 microprocessor architecture that has dominated the desktop and mobile scene since before some of you were even born, and will probably be a mainstay still yet for many more years to come. ![]() The same is true if you roll with AMD's latest silicon, the Phenom II X4. Believe it or not, your terrifically fast Core i7 fresh off Intel's assembly line contains DNA that dates back over three decades.
