RP-SM304A
The Parastream RP-SM304A is a replacement part for the Siemens SM304A integrated
circuit used in the Korg BX-3 and CX-3 combo organs, circa 1980. The Siemens SM304A
is a keyboard encoder that converts 32 parallel keyboard inputs into a serial stream.
These original Siemens parts are very difficult to find.
The RP-SM304A is a small printed circuit board that plugs directly into the 40-pin
socket of the BX-3/CX-3 KLM-244 board. It utilizes surface-mount CMOS technology
to realize its small size and low power consumption.
The Korg CX-3 uses two SM304A parts on one KLM-244 board. The BX-3 uses four SM304A
parts on two KLM-244 boards. An adapter socket (23-00040615) is included with each
RP-SM304A to facilitate mounting of the RP-SM304A in some circuit boards.

RP-SM304A datasheet and the
RP-SM304A installation instructions. There is also a
FAQ page for Frequently Asked Questions.
Key Benefits
- Functional replacement for the original Siemens SM304A part in most applications.
- Plugs directly into the IC socket on the PC board.
- SM304As may be replaced one at a time — Some other solutions require both to be
replaced at the same time.
