[vin41]
The Intel iSBC 80/10 was a groundbreaking single board computer introduced by Intel in 1976. It was one of the first products to integrate a microprocessor, memory, and I/O onto a single printed circuit board.
Key Features
- Processor: Intel 8080A 8-bit CPU
- Memory:
- 1K bytes of static RAM
- Sockets for up to 4K bytes of ROM/EPROM
- I/O:
- 48 programmable parallel I/O lines using two Intel 8255 Programmable Peripheral Interfaces
- Programmable serial interface using Intel 8251 USART
- Bus: MULTIBUS interface
- Board size: 6.75 x 12 inches
Historical Significance
The iSBC 80/10 was a pioneering product in several ways:
- It was Intel’s first single board computer, integrating CPU, memory and I/O on one board
- It helped establish the MULTIBUS standard, which became an important early computer bus standard
- It was part of Intel’s strategy to expand from just selling microprocessors to offering complete microcomputer solutions for OEMs
- It paved the way for future single board computers and helped accelerate the microcomputer revolution of the late 1970s and early 1980s
