Apricot PC


The Apricot PC was a personal computer produced by Apricot Computers. Released in late 1983, it was Apricot's first computer made for business use.
The press received it well, especially for the high resolution of its time and its trackball cable.
It used an Intel 8086 processor running at. A 8087 math co-processor was optional. The amount of memory was, expandable to. CRT green-screen 9" with text mode or graphics. Equipped with two floppy discs and a keyboard with an integrated LCD display. Released in 1983, it achieved success in the United Kingdom.
The Apricot Xi was a similar computer released in 1984, with a hard drive instead of a second floppy-drive.

Software

Due to an IBM PC incompatible BIOS, trying to run a software package like dBase III would result in a system crash.
The system was delivered with SuperCalc, and several system utilities, asynchronous communication, an emulator for, Microsoft Basic-86, Basic Personal and ACT Manager. Optionally available were Microsoft Word, Multiplan, WordStar, dBase II, C-Pascal, UCSD Pascal, C, Fortran, COBOL and.

IBM PC compatibility

The manufacturer did not completely clone the IBM BIOS, so although it ran MS-DOS and CP/M-86, it was not IBM PC compatible as the underlying system BIOS and hardware was very different. An Intel 8089 I/O controller was used, instead of the Intel 8237 DMA chip used in IBM computers; the ROM was only a simple boot loader rather than a full BIOS; and there was no 640k barrier. The floppy disk format was "not quite compatible"; attempting to read an ordinary PC FAT floppy in an Apricot, or vice versa, would result in a scrambled directory listing with some files missing.
Apricot later offered the possibility of converting the computer into an IBM compatible PC by replacing the motherboard with one equipped with an Intel 80286 processor.
