The superbaknit Interface-A is the electronics used by the SuperbaKnit box to perform needle selection. You may have multiple superba, Singer, White or Phildar knitting machines that you want to use with SuperbaKnit. You can use one SuperbaKnit box with each of several knitting machines; you need one interface per machine.
The SuperbaKnit Interface-A is used for Memo II, 624 and 9000 knitting machines.
NOTE: This is the interface board A ONLY. It is used as an extra supplement for a second machine with the SuperbaKnit Kit.
