The '''Aleste 520EX''' is a [[Clones|clone]] of the Amstrad CPC 6128 developed 1993 Patisonic in Omsk (Siberia). The Aleste is quite rare. The only existing photos are from http://aleste520.narod.ru. According to Patisonic themselves, they ''"produced several dozens of the model, some of them was in 'kit' form"''.
Additionally to the standard CPC6128 features, it includes a number of additional extra features: Optional '''64-color''' palette, '''double color depth''' (eg. 16 color at high 320x200 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 computer works with Amstrad [[CP/M]] and MSXDOS as well (note: MSXDOS is a CP/M clone, which uses a FAT filesystem, as used on MSX and MS-DOS computers, instead of the normal CP/M filesystem).
