Q5. Can I move my LT around while it is turned on ? A. With a dual-FDD LT, it should be okay to move it around as long as both drive access LEDs are off. Moving it in the middle of a disk access is definitely not recommended. With the hard disk model, the HDD motor is normally on, even if there is no drive access. Simply turn the HDD power switch (on the back of the LT) off. When you're finished moving, turn the HDD power back on. Q6. How do I use a color CRT with my LT? A. Set DIP switch 4 (at the top of the keyboard) to the OFF position and connect the monitor to the connector labeled CRT on the back of the LT. The switch setting can be changed while the computer is turned on: However, some applications may not operate correctly. If this happens, turn the LT off, wait at least 5 seconds, then turn the power back on. This will assure correct operation. Q7. Can I use an EGA monitor with my LT? A. Certainly. It will work just like connecting an EGA monitor to a CGA card in a desktop PC - that is, you won't get the high-resolution graphics and the denser character cell in text mode. Q8. Are the option slots compatible with the IBM PC/XT? A. The shape and size of the option slot connectors are different, so existing option cards cannot be used. However, the signal, data and power supply lines are the same as the PC/XT. Q9. Can third-party option cards be installed in the LT? A. Since the form factor of the connectors is unique to the LT, at present only the modem and hard disk controller made by Epson can be used. Q10. A. Can an 8087 be used? No, no socket is provided for a numeric co-processor. One of the main reasons is that an 8087 consumes a relatively high amount of power, which would adversely affect battery life.
