The Acorn Business Computer - ABC 310

The Acorn Businesss Computer 310 was a computer built around the Intel 80286 16-bit processor with a 6502 processor for I/O functions. The computer came with a whopping 1MByte of RAM, a color monitor, a 720k 5.25" Floppy Disk Drive, and a 10MByte Hard Drive. The operating system was DOS 286+, and the machine also came with the GEM graphical user interface.

The ABC 310 was the last in a series of eight ABC computers:

  • ABC Personal Assistant

Intel 80286 CPU

The Intel 80286 is a 16-bit microprocessor introduced in 1982. It was the first 80x86 processor with a separate, address and data bus, the first to introduce protected virtual address mode or protected mode, as well as built in memory management abilities. The 80286 is instruction compatible with the 8086 and the 8088 processors. It contained all the 8086, the 80186 instructions, and also new instructions to handle protected mode.
