+
+TK Extended was a local version of [PC-XT](/museum/ibm-pc-xt-model-5160/), launched by Microdigital in 1988.
+
+To minimize the technological gap between American and Brazilian models, the manufacturer offerred an upgrade card, named **Cometa 286** (Comet 286), which goal was to replace the processor with a 7.15 MHz 20286 Intel processor, and also a 20287 math co-processor.
+
+This model marked the end of Microdigital, the same manufacuter of TK family, which included Sinclair ZX-81 (**TK-85**), Spectrum ([TK-90](/museum/microdigital-tk-90x/) and [95](/museum/microdigital-tk-95/)) and also Apple licensed products adapted to meet Brazilian laws regarding national content.
+
+Thanks to **Roberto Isiri** for information and picture.
