    • Michael Böhmer from E3B describes the required hardware patch
  • up to 5 ISDN Blasters can be installed into one Amiga
  • supported by NetBSD
  • bugs
    • the card configures with a chained config request, so the Amiga thinks the card in the slot behind the Blaster is located on the same PIC - this bug is mostly harmless and correctable
    • the card stores only the upper three bits of the base address, assuming that it will get a place in the address space between 0xe80000 and 0xef0000 - this bug is not correctable
    • the address decoding does not differentiate between the ISDN chipset and the expansion socket - this bug is only noticeable when an expansion module is present; it is correctable
