To reduce the cost of MSX computers, many MSX models used a custom IC known as "MSX-Engine", which integrated glue logic, 8255 PPI, YM2149 compatible soundchip and more, sometimes even the Z80 CPU. However, almost all MSX systems used a professional keyboard hard-built into the machine instead of a detachable chiclet keyboard, which made the MSX computer more expensive compared to the original SV-328. This was a trade-off because while Microsoft's MSX BASIC made the MSX computer competitive, it was still somewhat expensive for a home computer.
