　※ When you look at the board with card edge side to the right, pin shorts on top and center
　　Is ON, and the pin short at the bottom and center is OFF.
　※ In the case of PC-9801VX0 / 2/4, set it to ON, and in slots other than slot 1.
　　Wear.In the case of PC-9801VX01 / 21/41, UX21 / 41, PC-286V, it is in the setting of JP
　　It can be attached to any slot regardless of it.
　※ Always set to OFF when using the expansion I / O unit.
　※ When JP is set to ON, when accessing memory in 80286 CPU mode
　　The double speed access function works.When OFF, memory access takes 700ns,
　　When ON, 300 ns.However, this function is an I · O bank method of 080000 to 09FFFFh
　　Valid only for additional RAM.

Expand PC-9801 / E / F / M / U / VF / VM / UV to 512KB / 640KB with NEC's expansion RAM board
If you use this board in I / O bank extension mode,
Setting change is required.This makes all bank numbers 00 to FFh available:
・ PC-9801UV2 + PC-9801-21 + PC-9801-21
　→ Remove one 128KB RAM module in the main unit and set the memory capacity to 512KB.
・ 384 KB system + PC-9801-02 / N / L (+ PC-9805)
　→ Open 4 to 10 of 2x6 series jumper switch of PC-9801-02 / N / L.
　(3-9, 5-11, 6-12 shorted).
・ 384KB system + PC-9801-31 / 41,384KB system + PC-9801-31 + PC-9801-21
　→ PC-9801-31 / 41 2x2 series jumper switch SW2 512-640K pins
　　Make it open.

Add PC-9801 / E / F / M / U / VF / VM / UV to 640KB with I / O bank type RAM board
Can be extended when using this board in I / O bank extension mode
Bank numbers have the following limitations:
· 384 KB system + PIO 9034-2, 256 KB system + PIO 9034-3,
　128KB system + PIO-9134
　→ Prohibited bank number = 01h to 7Fh, Available bank number = 80h to FFh
・ 384KB system + PIO-9234-0.25M
　→ Prohibited bank number = 01 h, Available bank number = 02 h to FF h
・ 128KB system + PIO-9234-0.5M
　→ Prohibited bank number = 01h, 02h, 03h, Available bank number = 04h to FFh
※ When bank memory is expanded by PIO-9234 (G) series expansion RAM board
　The bank number is displayed on the screen when TM9234 is executed.Also
　In the case of PIO-9234-1.5M / 3M, the 4/8 bank following the added bank is
　It becomes a prohibition bank.
