Apricot XI Prototype

The Apricot PC was Apricot Computers' first personal computer made for business use. It had two 3.5" floppy drives and a keyboard with an LCD screen. It was released in 1983, and achieved success in the UK. Although it ran MS-DOS and CP/M, it was not an IBM PC compatible as the underlying hardware was very different. An Intel 8089 I/O controller was used, instead of the IBM's 8237 DMA chip; the only ROM was a simple boot loader rather than a full BIOS; and there was no 640k barrier.
 
The Apricot Xi was a similar computer, but with a hard drive instead of the second floppy.
 
Our XI was an Apricot Development machine without an Xi badge and a case serial number of MF 067127.
