Oh, this can tell children that when Lenovo Hanka was developed, the computer only had the interface of isa bus, and pci was a new bus that later appeared to replace ISA bus. In the era of pci bus, the computer processing ability has been greatly improved, and the operating system has already supported Chinese well, so there is no need for separate hardware to support Chinese input and processing.
background knowledge: in the early days of computer use, due to the limited processing capacity of the computer, in order to improve the efficiency of the computer and reduce frequent access to the memory in the process of Chinese character input, Hanka was developed.
