PC 30-III
Basically, a PC 30-III is a PC 40-III with no onboard VGA, a 20MB HDD (instead of 40MB) and an added EGA video card. There are two versions: One with a standard PC 40-III mainboard where all the VGA components simply were not installed, and a later version with a “real” PC 30-III mainboard. The silk screen between the ISA slots either says “PC 40-III” or “PC 30-III” respectively.
Comes with original box, boxed monitor (?) and boxed keyboard.
Probably unused unit, both floppies had been removed by dealer.
