As for home computers, most common probably were ones based on articles in "Radio" magazine (Micro-80, Radio-86, Mikrosha (Mass-manufactured ver of one of those two), Orion (actually, a nice one, closest Western analogue would be ZX Spectrum 128, although Orion had better graphic capabilities, but no dedicated sound chip. )
BTW, Micro-80 (and both its successors) were heavily influenced by TRS-80 but weren't really clones (They used Soviet copy of Intel 8086 CPU, not imported Z80x and standard TV set for monitor, had some other tweaks and software was rewritten pretty much from scratch as well.) Also, number 80 is a coincidence
