Seeing the success of the ZX Spectrum, the company Tangerine (which produced one of the first kit computers based on the 6502) launched this computer under its subsidiary Oric, which was slightly cheaper, had an RGB monitor output, a sound chip and a better keyboard... but its ROM had numerous bugs.

A repackaged 800XL with a new case and keyboard.
The US and Canadian versions of the 65XE had no PBI or expansion ports.

The 65XE was called the 800XE in Germany and Czechoslovakia, to capitalize on the popularity of the 800XL model in Europe.

Its bigger brother, the 130XE, came with 128KiB of RAM and an Enhanced Cartridge Interface (ECI) instead of a PBI.

Commodore's last 8-bit computer, introduced three years after the successful Commodore 64, with which it was almost completely compatible.

It was intended to compete with the Apple Macintosh and the IBM PC.

The C128's principal hardware designer was Bill Herd.

Hard drive:
Operating system: BASIC
Innovations: It was capable of working with 256 colors and had a maximum resolution of 672x256 pixels (672x512 in interlaced mode):
The most commonly used modes were 672x512 pixels in two colors and 256x160 pixels with 16 colors. The 180x80 pixel mode allowed the use of all 256 colors.
It had three sound channels plus one for white noise.

At the height of the 8-bit home computer boom, Locumals, a Hong Kong company, decided to enter the newly emerging market, creating a computer that sought to overtake its competitors. It ended up being a resounding failure.
Despite having superior technical specifications, brands like Amstrad and Spectrum were already established in the market, which, combined with continuous delays in its release (two years after its introduction in 1983), spelled doom.
Only in Hungary, where the remnants of the production ended up after the closure, did it have any impact.
In Germany, it is known as the Mephisto PHC.

Manufacturer: Amstrad
Launches: 1985
Manufactured in GB
CPU: Zilog Z80A @ 4MHz
Memory: 72 KB
Support: Cassette
Hard drive: None
Operating system: BASIC 1.1 ver. sin Ñ

An Amstrad distributed by Indescomp (the brand's distributor in Spain, which would later become the subsidiary Amstrad Spain) exclusively for the Spanish market. It was identical to the CPC 464, but had a printed circuit board in the ROM socket that included an 8KB RAM chip, increasing the original CPC 464's memory from 64KB to 74KB, theoretically to accommodate the new commands and routines of the new BASIC 1.1 it incorporated.
But this was only a ruse to avoid the 15,000-peseta tariff that all microcomputers imported into Spain with 64KB or less of RAM had to pay starting in August 1985.
Subsequently, all computer keyboards sold in Spain were required to be adapted to Spanish, so the Ñ key had to be added to the computer, and the translated ROM version of BASIC 1.0 was used.
A few months later, Spain joined the European Economic Community, so the import tax had to be eliminated.
Amstrad then incorporated the Ñ key into the original CPC 464 model and stopped selling the CPC 472 model.

A variant of the Dragon 200 modified specifically for the Spanish market, which expanded the ROM character set to include lowercase letters, letters specific to Spain such as ñ, ü, ç, and accented vowels, along with other symbols.
This was achieved at the expense of reverse video characters, since the original version of this computer only allowed capital letters.
