Introduction
The Sharp X1 Turbo was an improvement on the X1. Graphics capabilities had been upgraded to include a 640x400 mode, and it came with dual 5.25" disk drives for storage. THe machine had 64K RAM, came with Hu-BASIC built in ROM and had a 3-voice + white noise Programmable Sound Generator (The General Instrument AY-3-8910, the Yamaha YM2149, or the Yamaha YM2151 in later revisions).
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.
