Over the past few years Brasil based TecnoBytes have rapidly grown a good reputation as hardware supplier for MSX, with their OPL4 Shockwave sound card and the V9990 PowerGraph as the most well-known products. These cards are compatible with the Sunrise MoonSound and GFX9000 cartridges respectively.
Today, TecnoBytes have announced an upcoming hardware extension for MSX that brings something entirely new to the table: a Floating Point Unit (FPU) for MSX or in other words: a coprocessor that can take the performance of your MSX to the next level, provided there is software written for it. To make that happen, they have teamed up with the team behind the Oldbits Dev Studio who are going to produce a ready-for-use library to support the MSX FPU. According to TecnoBytes, using the MSX FPU should make it possible to do realtime calculations for a game that uses "Angry Birds" physics. Particularly combined with a V9990, this opens a whole world of new possibilities for MSX.
