- Use 2DD instead of 2HD. 98's FD has different rotation speed from
- IBMPC's one, that is, it is physicaly different. If you are luckey you
- can read directory some how, but that's all in an IBMPC. Toshiba's
- J3100 series may have 3-mode FD (1.44MbHD, 1.14MbHD, 640kDD) and can
- be used as a conversion tool.

- In this case, PC98's RS-232 is the standard. As you know, IBMPC's 9pin
- connector is non-standard. You can easily make conversion cable. But
- I forget its direction. If you fail try cross cable :-)

- As third solution, you can use Internal Modem of PC98.
