Q11.

What kind of mouse can I use?

Just about any mouse can be used with the LT, provided it uses the

RS-232C serial interface (like the Microsoft Serial-PS/2 Mouse).

Q12.

Can the amount of RAM memory be increased?

No. Epson does not provide any memory expansion capabilities.

Q13.

Can I use a light pen?

No. Even though the necessary I/O registers are present, there is no

connector for the light pen.

What kind of external FDD can use with the LT?

Q14.

The external FDD interface was designed to be compatible with the

Toshiba laptops (such as the T1100+), so any external 5.25" FDD that

works with a Toshiba will work with the LT. One such drive is the

model NTHLPFL from the Nth Group in Canoga Park, California. Their

phone number is (818) 883-5506.

Q15.

How many FDDs are supported by the LT?

As with most laptops, the ROM BIOS will support two FDDs. Even if

you have an external drive connected, you still can only access drives

A and B.

Q16.

When an external FDD is connected to the LT, which drive letter

should be assigned to the external drive?

DIP switch 2 (on the

drive will be A or B. Typically, you would assign it as A if you were

using copy-protected software that requires a "key" disk, or running

certain game programs that require booting from drive A. Otherwise,

it's a matter of personal preference.

Q17.

Is it possible to use a 360 KB and a 1.2 MB FDD?

No. The LT supports a 250 KB per second transfer rate, so the 360 KB

drive works fine. The 1.2 MB FDD uses a higher transfer rate and is,

therefor, not compatible.
