Apple IIGS was never released or sold, in Finland. Only 3 test setups were imported for testing, reviewing and for demo usage.
Tero Sand had one of these donated to and used it for programming and also for the Apple Klubi / Omenahyve magazine creation. This unit was later donated to another user but the unit is now been trashed away. Sadly.
Apple IIGS was reviewed in few magazines inc. MikroBITTI but also, Tekniikan Maailma and also PRINTTI-magazine in issue 17/1986.
Due copyright reasons, i can’t offer pdf’s out of those reviews.
