PERSONAL COMPUTERS

In most cases, the Personal Computer (PC) used with the C3 Maestro console is delivered with the Logic Board installed, its hard disk drive formatted and MS-DOS operating system software installed on the hard disk drive. The C3 Maestro application software is also installed on the drive.

BOARD SET-UP

IMPORTANT NOTE

Unless otherwise noted, all procedures in this manual should be performed in the order presented.

Hardware

Table 1 lists the PCs approved for use with a C3 Maestro console system. Use of an unapproved computer will void the console system's warranty and support services. Subsequent to the printing of this manual, additional PCs not listed in the table may be approved.

LOGIC BOARD

Normally, the Logic Board is configured correctly and installed inside the PC before the C3 Maestro console system is delivered to the customer. The following information is presented for reference only.

All positions of DIP switch SW1 on the Logic Board should be in the "ON" or "CLOSED" position. This sets the base address of the dual-port RAM chip on the board to D000:0000 (hex). SW1 switch should never be configured

in any other way. Figure 2 shows the "0000" setting.

Operating System Software

The PC will have either MS-DOS version 3.3, 5.x or

6.x installed on its hard drive. MS-DOS 5.x or 6.x is preferred. All Data General and Hewlett-Packard computers ship from the factory with either MS-DOS 5.x or 6.x. MS-DOS 4.x is not approved for use with the C3 Maestro console system.

SW2 − Interrupt (IRQ) DIP Switch

DIP switch SW2 on the Logic Board sets the board's interrupt request (IRQ) line. It should be set with position 1 "ON" or "CLOSED" and all other positions "OFF" or "OPEN". This sets the interrupt to seven (IRQ7). Normally, SW2 should not be configured in any other way. Figure 3 shows the setting. This setting is not a binary-code decimal equivalent representation of the interrupt number; the switch simply provides a single-pole four-throw switch function using four single-pole single-throw DIP switches.

Logic Boards previous to Rev. A were not equipped with SW2; the interrupt was hardwired as IRQ7.
