The photos show that they are Dimarzios and…that they are pickups.
A vintage Ibanez group or forum with knowledge of which Dimarzios were included in Ibanez Artist guitars in the 1970s-80s will give you the cleanest info.
All I can really do is ask you to hook the start and finish wires of each humbucker up to a multimeter, note the resistance, then swap one of the wires with the series connection wire so we get the measurement of an individual coil for further reference. The numbers will establish which ballpark we’re in, but it will still end up being an educated guess.
Best guess based on photos is original Super Distortion and original PAF - But a resistance measurement could prove or disprove that.
