At 1993, a company located at Omsk (Siberia) desighed and manufactured a clone of CPC6128 computer. The name of computer "Aleste 520EX". The coputer works with Amstrad CPM and MSXDOS as well. Thats because Aleste computer have two modes one is Amstrad mode, but second MSX mode have different memory management and additional graphics modes.
=== AMSTRAD MODE Amstrad Mode===
Computer have no any differences with CPC6128 instead of one addtional register with let switch to MSX mode.
=== MSX MODE Mode===
At this mode computer have different memory manager. The manager seems same like MSX mapper and could swicth ON any 16KB page of whole memroy at the any of 16KB page of CPU memory.
At the boot time coputer loads BIOS and MSXBDOS (BIOS for Disc Controlles) from a bood disc. After that COMMAND.COM (MSXDOS).
=== MAGIC SOUND Magic Sound===
Additional sound board MagicSound is a four channels smapler. Each channel has 8 bit per sample and 6 bits of volume per channel. Computer uses the board for playing STM (Scream Tracker) files. The sample's data containg at the Aleste's memory, that is possible because Aleste have support DMA access from external board to whole Aleste's memory.
=== VDP EMULATOR Emulator ===
Computer have "GameBios" with is emulator of VDP9938. it was sufficiently - to replace the first several kilos-byte of game and MSX2 game worked. Certainly, video processor MSX is by apparatus sharpened for the games, but they worked sufficiently rapidly to 8MGts of game on "alesta" in order in them to play. Game "FireBird" typical
"vertical scroller" worked very well.
=== FOTON Foton===
Another additional board FOTON is a "Light Processor". The board have D54 interface and Aleste with special FX application conrol over club's light.
