Sound Designer/Emulator II System Troubleshooting
Sound Designer/Emulator II System Troubleshooting

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”

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…
