ET-188 was an IBM PC XT compatible computer made by the Yugoslav company Novkabel (Novosadska fabrika kabela - Novi Sad Cable Factory) from Novi Sad (now Serbia) in the 1980s.

[1][2][3] Novkabel already had experience in developing computer systems (ERA 20, ERA 60 and others) which was used to make ET-188 as an original design, compatible with IBM PC XT.

[4] To save space and to lower the cost, ET-188 used 8 MHz Intel 80188 CPU, with integrated timer, DMA and interrupt controller.

ET-188 was offered to the public in 1985 and advertised in the Yugoslav computer press.

[5] An improved ET-188A model was in May 1986 presented to the public at the Belgrade International Fair of Technique and Technical Advancements with more RAM and a new redesigned case.
