Abstract

This article describes a technique to do arbitrary foreign language text processing on a personal computer. Three things are generally needed to process a national language. The processor requires a keyboard entry, a display on video screen and a printer for printing foreign text on paper. To provide for such arbitrary foreign language, representable by alphabet (not ideograms), a personal computer is modified to function to permit entry of arbitrary alphabets. For the video display, the normal personal computer ROM (read-only memory) chip for the display adapter (either mono or color) is replaced by EPROM (electrically programmable read-only memory) that stores a national language character font.

National Language Input/Output on Personal Computer

This article describes a technique to do arbitrary foreign language text processing on a personal computer. Three things are generally needed to process a national language. The processor requires a keyboard entry, a display on video screen and a printer for printing foreign text on paper. To provide for such arbitrary foreign language, representable by alphabet (not ideograms), a personal computer is modified to function to permit entry of arbitrary alphabets. For the video display, the normal personal computer ROM (read-only memory) chip for the display adapter (either mono or color) is replaced by EPROM (electrically programmable read-only memory) that stores a national language character font. Optionally, adding a single wire to the display adapter board makes possible the use of either of two 256-character sections of a 512-character EPROM. Switching between the two halves of the EPROM is done by software. The procedure is as follows: A. Replace the font display ROM by an EPROM in a socket. B. Cut Pin 21 from a 24-pin socket so that if the socket is plugged with a socket for a U33 on a mono board, no connection

is made to that pin. C. Cover pin 21 with insulating tape. D. Solder fuse (3.5 inch wire wrap wire will do) to the stub of the clipped pin on the socket. E. Solder the socket pin to the pin 7 of U58 on the mono board. F. Insert the socket into the socket for U33 G. Insert EPROM into the socket on U33...
