The '''Aleste 520EX''' is a [[Clones|clone]] of the Amstrad CPC 6128 developed 1993 by [[Patisonic]] in Omsk (Siberia). The Aleste is rare, according to Patisonic themselves, they ''"produced several dozens of the model, some of them were in 'kit' form"''.

In addition to the standard CPC6128 features, it includes a number of extra features: '''64-color''' palette, '''double color depth''' in slightly '''decreased horizontal resolution''' mode (eg. 16 color at 256x200 resolution), battery-backed '''Real Time Clock''' chip, '''512Kbyte RAM''' (of which 192K can be accessed as on 64K CPC with 128K dk'tronics memory expansion), '''8bit printer''' port, expanded keyboard matrix with '''10 additional keys''', two software controlled '''LEDs''', extended Expansion Port (with additional pins for '''DMA support''').

The above photos are showing a more or less fully assembled Aleste (the LEDs are missing, and, more important, there is no connection for an internal or external power supply attached to the mainboard - unless the owner used the Expansion Port connector to inject power supply voltages).

This version has 7pin+7pin sockets for printer (normal would be 5pin+7pin, though the extra pins are most probably left unused).

On "not confirmed" status of the article: yesterday I emailed request to [http://www.patisonic.com/ Patisonic] company and they confirmed that "Aleste" exists and produced in the company. --[[User:Nzeemin|Nzeemin]] 09:28, 19 September 2006 (CEST)
:You mean it's still produced???? [[User:Gryzor|Gryzor]] 14:15, 20 September 2006 (CEST)
:: No-no-no... (Sorry for my bad language knowledge.) They started to produce Aleste at 1993 and finished at the same year. They produced several dosens of the model, some of them was in "kit" form. [http://community.livejournal.com/ru_oldpc/10110.html Here] I posted my email discussion with a person from Patisonic firm (in Russian). --[[User:Nzeemin|Nzeemin]] 20:25, 28 September 2006 (CEST)

If anybody interested -- take a look at the repository: [https://github.com/LasDesu/Aleste-520EX]. Also here's forum discussion -- [http://zx-pk.ru/threads/20769-kompyuter-quot-aleste-520ex-quot.html]. So in 2016 someone restored the scheme and PCB, and recreated the machine. -- [[User:Nzeemin|Nzeemin]] ([[User talk:Nzeemin|talk]]) 18:26, 19 May 2017 (EDT)

I would like to emulate the Aleste 520EX in my emulator. Is it possible to talk (in English - sorry I dont know Russian) with the person who recreated the machine? Would then run some tests for me? [[User:Arnoldemu|Arnoldemu]]
: Feel free to write in English to the forum -- most guys there knows the language, or can use Google Translate at least. -- [[User:Nzeemin|Nzeemin]] ([[User talk:Nzeemin|talk]]) 07:02, 20 May 2017 (EDT)
