Prologica CP-200 (ZX81 Clone)
The CP-200 was a Brazilian clone of the Sinclair ZX81, produced in 1982. It was hardware and software compatible with the ZX81, but it was not an exact copy of the machine. There are two models of the CP-200, with the only difference that the first model had the Prologica logo in relief, and the cabinet was slightly smaller.
Later Prologica produced another version of the same machine, the CP-200s. The cabinet was redesigned and the computer had a video monitor output port added to it, and the power supply unit was now external.
CPU View - Zilog Z80 Family
The Z80 quickly became popular in the personal computer market, with many early personal computers, such as the TRS-80 and Sinclair ZX80, using the Z80 as their central processing unit (CPU). It was also widely used in home computers, such as the MSX range, SORD, and the Amstrad CPC, as well as in many arcade games. Additionally, it was also used in other applications such as industrial control systems, and embedded systems. The Z80 was widely used until the mid-1980s, when it was gradually replaced by newer microprocessors such as the Intel 80286 and the Motorola 68000.
The Z80 microprocessor was developed by Zilog, a company founded by Federico Faggin in 1974. The Z80 was released in July 1976, as a successor to the Intel 8080. It was designed to be fully compatible with the 8080, but also included new features such as an improved instruction set, more powerful interrupts, and a more sophisticated memory management system.
