Varix VC 50
The VC 50 was an 8-bit computing, 8-bit home computer produced in Brazil by the company ''Engetécnica'' (later called ''Varix'') between 1983 and 1985. It was one of the many Clone (computing), clone machines based on the TRS-80 Color Computer introduced during the Brazilian "Protectionism, Market Reserve", like the Codimex CD-6809 or Prológica CP-400, Prológica CP 400 COLOR. History Launched in 1983, the initial target audience for the VC50 was mainly agricultural companies, sugarcane mill, sugar mills and distillation, distilleries. The machine, originally equipped with an integrated floppy disk, floppy disk drive and numeric keypad, came to be used as a controller for industrial manufacturing processes and for financial and production calculations related to agriculture. ''Varixx'', formerly ''Engetécnica/Varix'', developed specific software packages for these usages (including for example of sucrose content control or cargo, freight price list generation).

Motorola 6809
The Motorola 6809 ("''sixty-eight-oh-nine''") is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS Technology 6502, including a hardware multiplication instruction, 16-bit arithmetic, system and user stack registers allowing re-entrant code, improved interrupts, position-independent code, and an orthogonal instruction set architecture with a comprehensive set of addressing modes. The 6809 was among the most powerful 8-bit processors of its era. It was also among the most expensive; in 1981 single-unit quantities were compared to for a Zilog Z80 and for a 6502. It was launched when a new generation of 16-bit processors were coming to market, like the Intel 8086, and 32-bit designs were on the horizon, including Motorola's own 68000. It was not feature ...
