MPC3000 Options

The SMPTE Option

Expanding the Sound Memory

This section describes the various options available for the
MPC3000. To purchase any of these items, contact your Akai re-
tailer. These options should be installed only by an authorized Akai
retailer or service center.
The I-0055 SMPTE option gives your MPC3000 the ability to play
in sync to externally received SMPTE sync signals in one of four
frame formats: 24, 25, 29.97 drop, and 30. This option is not needed
to generate SMPTE code.
To Service Technicians
Installation of the I-0055 SMPTE/EBU IC chip
1. Open the operation panel of the MPC3000; Detach the CPU jack
daughter board (L4012B509B) on the CPU main board
(L4012A5010) by removing the 3 screws.
2. Attach the I-0055 IC chip to the IC26 socket on the CPU main
board (L4012A5010). Make sure that the No. 1 pin of the I-0055
chip is correctly placed as guided by the mark.
3. Replace the CPU jack daughter board (L4012B509B) on the CPU
main board (L4012A5010).
The MPC3000 includes 2 megabytes of sound memory but is ex-
pandable using common SIMM 1 megabyte or 4 megabyte memory
modules and an 8 megabyte memory board from Akai, the
EXM3008. Internally, there are two SIMM sockets and one connec-
tor for an Akai memory board. When the MPC3000 is shipped from
the factory, its SIMM sockets are empty and the Akai connector
contains an Akai 2 megabyte memory board. You can expand the
memory in either or both of two ways:
1. In the SIMM sockets, install either a pair of 1 megabyte SIMMs
(adding 2 megabytes) or a pair of 4 megabyte SIMMs (adding 8
megabytes). You must fill both sockets and the 2 SIMMs installed
must be identical. The SIMM modules must have a speed of 150
nanoseconds (ns) or faster.
2. Remove the standard 2 megabyte Akai memory board from its
socket and replace it with an Akai 8 megabyte memory board, the
EXM3008.
