EPSON EPSON AMERICA INC. SERVICE DEPARTMENT PRODUCT SUPPORT BULLETIN DATE: 02/25/88 SUBJECT: Equity LT - Common Questions and Answers PSB #: 0036 Q1. Can I switch the CPU speed between 4.77 MHz and 10 MHz while the L T is in operation ? A. Yes - the CPU and clock circuitry are fully synchronized. Q2. How can I adjust the speaker volume? A. You can't. There is no provision, either hardware or software, for volume control. Q3. What type of keyboard is the LT keyboard compatible with? A. The LT keyboard is compatible with the "old-style" PC/XT 83-key keyboard. The only difference is the addition of the "SysReq" key and a second "Ctrl" key. Since the ROM BIOS is compatible with that of the "new-style" XT, support is provided for the "SysReq" key. The LT keyboard has two "Ctrl" keys, to the left and right of the space bar. Both keys return the identical scan code (1Dh), so it is not possible to distinguish between the left and right keys, as can be done with the enhanced AT-style 101-key keyboard. Q4. What is the shock resistance of the floppy and hard disk drives? A. Shock resistance of the FDD is as follows: Operation 5G Non-operation 50G Shock resistance of the HDD is as follows: Operation Read 5G Write 3G Non-operation 70G Equity LT - Common Questions and Answers - Page 1 of 9
