The original Roland 100m module used the MN3004 512-stage BBD chip which is now rare (and therefore expensive). This module is therefore designed to operate with a variety of the MN-Series BBD chips. It has already been tested successfully with the MN3004 and the MN3007 (1024 stage), and is currently being tested with the MN3207.
The module also includes the same LFO as the original.
