Hardware Installation

1.Shut the host computer power off.

2.Remove the computer cover.

3.Remove the expansion slot cover of an unused slot.

4.Handle the PCRTC only by its edges. Avoid touching any conductors on the PCRTC. Install the PCRTC into the slot. Be certain that the card is inserted completely into the slot.

5.Secure the card with the mounting screw from the slot cover.

The PCRTC is shipped with the oscillator halted to extend battery life. To start the PCRTC, the card must be initialized. This can be done using the command line option PCRTC /I found in Chapter 3 of this manual or by the device driver. If you are using the device driver, it will automatically initialize the PCRTC when it loads. Upon initialization, a warning will appear stating that the oscillator was halted and date and time information may be corrupt.

Software Setup

Place the 3.5” floppy disk in your “A” drive. Run the installation program by typing “INSTALL” <Enter>. The files installed to your hard drive include the PCRTC device driver, the shareware program Timeset and three example files written in C, Pascal, and QuickBASIC. These files demonstrate how to make function calls to the PCRTC from within a program and are listed in Chapter 3. The device driver will also be automatically installed in your CONFIG.SYS file and set for address 200. If you require a different address, remember to edit the CONFIG.SYS file to set the address to match PCRTC hardware.
