Tatung Einstein TC01

Autopsy:

from Wikipedia homepage:

The Einstein was released in the United Kingdom in the summer of 1984, and 5,000 were exported back to Taipei later that year. A Tatung monitor (monochrome or colour) and dot matrix printer were also available as options, plus external disc drives and an 80 column display card. It was also capable of emulating the Spectrum 48k with the “Speculator” addon.

More expensive than most of its rivals, and lacking an obvious niche market other than technically-advanced home programmers, the Einstein was commercially unsuccessful. A later, revised version, called the Tatung Einstein 256 suffered a similar fate.

The machine was physically large, with an option for one or two built-in three-inch floppy disk drives manufactured by Hitachi. At the time, most home computers used ordinary tape recorders for storage. Another unusual feature of the Einstein was that on start-up the computer entered a simple machine code monitor, called MOS (Machine Operating System). A variety of software could then be loaded from disk, including a CP/M-compatible operating system called Xtal DOS (pronounced ‘Crystal DOS’, created by Crystal Computers in Torquay), and a BASIC interpreter (Xtal BASIC). Thanks to the reliability of the machine, and ample memory, the machine proved useful by many software houses to use for programming, and then porting the code to the machines they were made for, Spectrum 48k, Amstrad CPC, Commodore C64, this later stopped when the PC and Atari ST would emerge as the development systems of choice.

Radio Shack TRS-80 Model 1 / Expansion / Floppy / Video Display

Radio Shack TRS-80 Model 1 / Expansion / Floppy / Display

Autopsy:

from Wikipedia:

TRS-80 was Tandy Corporation’s desktop microcomputer model line, sold through Tandy’s Radio Shack stores in the late 1970s and early 1980s, and one of the earliest mass-produced personal computers. The first units, ordered unseen, were delivered in November 1977, and rolled out to the stores the third week of December.

The line won popularity with hobbyists, home users, and small-businesses. Tandy Corporation’s leading position in what Byte Magazine called the “1977 Trinity” (Apple, Commodore and Tandy) had much to do with Tandy’s retailing the computer through more than 3,000 of its Radio Shack storefronts. Notable features of the original TRS-80 included its full-stroke QWERTY keyboard, small size, its floating point BASIC programming language, an included monitor, and a starting price of $600.

The pre-release price was $500 and a $50 deposit was required, with a money back guarantee at time of delivery. One major drawback of the original system was the massive RF interference it caused in surrounding electronics. Stricter FCC regulations on interference led to the Model I’s replacement by the Model III.

Radio Shack announced the TRS-80 (Tandy Radio Shack) at a New York City press conference on August 3, 1977. It cost $399, or $599 with a 12″ monitor and a Radio Shack tape recorder as datacassette storage. Before this, the most expensive product Radio Shack sold was a $500 stereo.

The company hoped that the new computer would help Radio Shack move into higher-priced products, and improve its “schlocky” image among customers. Small businesses were the primary target market, followed by education, then consumers and hobbyists. Despite its hobbyist customer base, Radio Shack saw hobbyists as “not the mainstream of the business”. Although the press conference did not receive much media attention due to a terrorist bombing elsewhere in the city that day, “six sacks of mail” arrived at company headquarters asking about the computer, and over 15,000 people called Tandy to purchase a TRS-80, paralyzing its switchboard.

Unlike competitor Commodore—which had announced its PET several months earlier but had not yet shipped any—Radio Shack began shipping computers by September. Still forecasting 3,000 sales a year, the company sold over 10,000 TRS-80s Model Is in its first one and a half months of sales, and over 200,000 during the product’s lifetime.
