- expansion port for the Hypercom 3i and Hypercom 3 Phone I/O modules
- due to a couple of bugs in the ISDN Blaster PALs, the expansion port is not ready to take any expansions by default
- 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
