Sinclair ZX80

The MicroAce was a 1980 Sinclair ZX80 home computer clone, designed and manufactured by CompShop and distributed in the USA by MicroAce of Santa Ana, California. [1] [2] [3]

Contents

It was also sold in Australia and was distributed by Dick Smith Electronics.

Description

Advertised as "a microcomputer for everyone at a micro price ... a complete computer for $149.00 for 1K [RAM] kit" with optional 2K RAM, [4] [5] it was an unlicensed clone of the Sinclair ZX80 and had an identical, yet obfuscated copy of the ROM by means of a byteswap. [6] [7] Some time later, between 1980 and 1981, MicroAce settled with Sinclair and licensed the ROM of the ZX81. [8] [9]

Reception

BYTE stated that the assembly instructions were insufficient for those inexperienced in kit assembly, and suggested that beginners learn how to solder first. It found some fit and finish issues with the completed computer, and criticized MicroAce for being unresponsive to questions. The review stated that "if you recognize the limitations of the machine and don't expect too much, then I think you can buy the MicroAce kit with confidence", albeit strongly recommending the 2K RAM option.

The Jupiter Ace by Jupiter Cantab was a British home computer released in 1982. The Ace differed from other microcomputers of the time in that its programming environment used Forth instead of the more popular BASIC. This difference, along with limited available software and poor character based graphic display, limited sales and the machine was not a success.

The British Broadcasting Corporation Microcomputer System, or BBC Micro, is a series of microcomputers and associated peripherals designed and built by Acorn Computers in the 1980s for the BBC Computer Literacy Project. Designed with an emphasis on education, it was notable for its ruggedness, expandability, and the quality of its operating system. An accompanying 1982 television series, The Computer Programme, featuring Chris Serle learning to use the machine, was broadcast on BBC2.

Each time Intel launched a new microprocessor, they simultaneously provided a system development kit (SDK) allowing engineers, university students, and others to familiarise themselves with the new processor's concepts and features. The SDK single-board computers allowed the user to enter object code from a keyboard or upload it through a communication port, and then test run the code. The SDK boards provided a system monitor ROM to operate the keyboard and other interfaces. Kits varied in their specific features but generally offered optional memory and interface configurations, a serial terminal link, audio cassette storage, and EPROM program memory. Intel's Intellec development system could download code to the SDK boards.

<span class="mw-page-title-main">Home computer</span> Class of microcomputers

Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single nontechnical user. These computers were a distinct market segment that typically cost much less than business, scientific or engineering-oriented computers of the time such as those running CP/M or the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business computers. Their most common uses were word processing, playing video games and programming.

The ZX81 character set is the character encoding used by the Sinclair Research ZX81 family of microcomputers including the Timex Sinclair 1000 and Timex Sinclair 1500. The encoding uses one byte per character for 256 code points. It has no relationship with previously established ones like ASCII or EBCDIC, but it is related though not identical to the character set of the predecessor ZX80.
