Sound Designer/Emulator II System Troubleshooting Sound Designer/Emulator II System Troubleshooting By Evan Brooks Digidesign Inc. Section 1 Macintosh Setup 1. Make sure the Mac is a 512K version. Add-on memory beyond the 512K may or may not work properly. 2. Boot the Mac using one of the Sound Designer Master Disks. 3. Make sure that NONE of the following items are installed in the Mac’s RAM at this point: a. RAM Disks b. Turbochargers or RAM cache systems c. RAM-resident debuggers such as Macsbug d. Anything else co-resident in RAM besides the System and Finder 4. Double click on the Sound Designer program icon. The program should boot and come up with an Untitled wave window. 5. Proceed to the Emulator II Setup section. Section 2 Emulator II Setup 1. Open up the Emulator by removing the 8 screws on the bottom of the unit around the periphery and remove the 4 screws at the top of the back panel. Then gingerly slide the top of the Emulator around and over the keyboard, exposing the circuitry inside. 2. DO NOT TOUCH THE POWER SUPPLY EVER!! 3. Determine if the Logic Board is a Rev. 0 or a Rev. 1 board as follows: The logic board is the large circuit board bolted to the bottom of the E2 on the Right-hand side. It has a smaller Memory Option circuit board mounted ON TOP of it. The Rev, number of the Logic Board is silk screened in WHITE on the portion of the logic board which is closest to the keyboard, and directly under the Memory Option board. You will have to lower your neck and head to see it. It will say something like “Rev. 0” or “Artwork Rev. 1”. IF THE LOGIC BOARD IS REV. 0, read the next section, titled “For Emulators with Rev. 0 Logic Boards”. IF THE LOGIC BOARD IS REV. 1, go to the section titled “For Emulators with Rev. 1 Logic Boards” Enhanced by The Emulator Archive 2002 www.emulatorarchive.com Page 1 Not for reproduction or resale Sound Designer/Emulator II System Troubleshooting For Emulators with Rev. 0 Logic Boards An RS422 interface board must be installed on Rev. 0 logic boards to permit the Macintosh and Emulator II to communicate. This board converts the serial port On the Emulator to run using RS422 protocol instead of RS232 protocol, which is slower. The interface board merely replaces the RS232 driver chip and receiver chip with the corresponding RS422 driver chip and receiver chip. Check to see if a RS422 interface board has been installed on the Rev. 0 logic board: The interface board is roughly 1.5” X 2.0” and plugs into the IC sockets vacated by IC132 and lC108 via DIP plugs. If this board is not present, then remove the RS232 drivers (1488 and 1489) at 10132 and 10108 and obtain an R…
