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).
