Black Card Interface (Backpack)
These versions of BCI allows you to use a single made for the Tiptop Audio Z-DSP on your EricaSynths Black Hole DSP MK1 / MK2 and PicoDSP modules without adding extra HP.
The Black Hole DSP MK1 version plugs on the expansion ROM connector and requires no modification.
The Black Hole DSP MK2 and PicoDSP versions plug to the ROM programming connectors and requires desoldering the original EEPROM which might void your warranty.
