MMP-98N, MMP-98N2 (Multimedia pack 98n) (コンピュータテクニカ) PC-9801NS, NS / E, NS / T, NC, NA, NA / C, NS / R, NS / A, NX / C, PC-386NOTE AR, AE, Composite interface BOX mounted on 110-pin expansion bus of PC-486NOTE AS. graphic Equipped with accelerator, PCM sound source and CD-ROM interface.PC expansion bus Remove the cover and attach it. Power consumption 1.75 W. Because the power consumption at the expansion connector will exceed the allowable power consumption of the main unit, Adapter to connect MMP-98N to other expansion connectors (with through output of expansion connector SCSI_I / F etc.) Do not connect at the same time. The CPU mode of the main unit should be "HIGH".Also, EMS page with standard 256 color display function The EMS function is not used because the memory address of the frame (C000H segment) is used. Choose.When installing the display driver, the installer When EMM386.exe is found, its option switch is automatically rewritten, EMS page The frame address is shifted or set to not use EMS.Resume Function not supported. For models with built-in sound function such as PC-486NOTE AS, the sound of the main unit Set BIOS to "do not use". The compatible OS is Windows 3.1.We are using Microsoft version Windows 3.1 in the body made by Epson If the included “Sound Driver for W3.1 & DOS Utility” One FD in combination with "Display Driver for Windows 3.1 & CD-ROM Utility" Can not be used withIn this case, from Computer Technica (Device Sales Division) A compatible disc is available free of charge. ● Graphic accelerator CRT output: 640 × 400 dots or 800 × 600 dots, 256 colors (non-interlaced).
