This model also includes an RGB II module for connecting a colour monitor. The mainboard has different layout than Pravetz 8C and supports adding of up to 1MB of memory directly on the mainboard. The model name on the motherboard simply reads "CPU 8S" as opposed to previous models, which had the full computer name on the mainboard (such as Pravetz 8C).
