The Applix 1616 was a kit computer with a Motorola 68000 CPU, produced by a small company called Applix in Sydney, Australia, from 1986 to the early 1990s. It ran a custom multitasking multiuser operating system that was resident in ROM. A version of Minix was also ported to the 1616, as was the MGR Window System. Andrew Morton, designer of the 1616 and one of the founders of Applix, later became the maintainer of the 2.6 version of the Linux kernel. History Paul Berger and Andrew Morton formed the Australian company Applix Pty. Ltd. in approximately 1984 to sell a Z80 card they had developed for the Apple IIc that allowed it to run CP/M. This product was not a commercial success, but Paul later proposed they develop a Motorola 68000-based personal computer for sale in kit form. The project was presented to Jon Fairall, then editor of the Australia and New Zealand electronics magazine Electronics Today International, and in December 1986, the first of four construction articles was published as "Project 1616", with the series concluding in June 1987. In October and November 1987, a disk controller card was also published as "Project 1617". Over the next decade, about 400 1616s were sold. Applix Pty. Ltd., was in no way related to the North American company of the same name that produced Applixware. Hardware Main board The main board contains: a Motorola 68000 running at 7.5 MHz, or a 68010 running at 15 MHz. 512 kibibytes of Dynamic RAM between 64 kibibytes and 256 kibibytes of ROM on board bit mapped colour graphics (no "text" mode), with timing provided by a Motorola 6845 CRT controller. The video could produce 320x200 in 16 colours, or 640x200 in a palette of 4 colours out of 16, with a later modification providing a 960x512 monochrome mode. The frame buffer resided in system memory and video refresh provided DRAM refresh cycles. The video output was able to drive CGA, EGA, MGA and multisync monitors. dual RS-232 serial ports using a Zilog Z8530. a parallel port for Centronics-type printers or general purpose I/O. This was provided by a Rockwell 6522 Versatile Interface Adaptor, which was also the source of timer interrupts. 4 channel analog/audio output via an 8 bit DAC and multiplexor. software audio/analogue input via the DAC and a comparator. a PC/XT keyboard interface. The main board also had four 80-pin expansion
