The machine was based on a powerful (for the time) 16-bit single-chip K1801VM1 CPU, clocked generally at 3 MHz. It was almost perfectly compatible with Digital Equipment Corporation's LSI-11 line, though it lacked the EIS and further command set extensions. The manufacturer also closely copied the PDP-11's internal architecture. Each model had one free card slot, which was electrically, but not mechanically compatible with the Q-Bus. The first versions had 32 KB onboard DRAM, half of which was used as video memory. That was extended to 128 KB in later models, with video memory extended to two 16 KB pages.

Cool system? ))))))))
