The Jupiter Ace
The Jupiter Ace is very similar to the ZX-81. This should be no surprise as the designers of this computer are Richard Altwasser and Steven Vickers, who both played a major role in the development of the Sinclair Spectrum ZX-81.
The ACE can, via a small adapter, use the ZX-81 RAM expansion modules, to enable up to 64KByte of RAM. The machine came with the language FORTH built in instead of BASIC in many other computers.
FORTH is a small, interactive language that is many times faster in execution than BASIC, but it has a much steeper learning curve. This may have added to the fact that the Jupiter ACE was not very succesful.
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.
