Here’s a rarity, only some dozens made:
The Aleste 520EX is a 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” .
It’s compatible with CPC6128, with extra graphics modes, ability to support more RAM, improved expansion port, and so on. Here’s a photo of the machine (the board) fitted into an MSX-compatible case:
