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
