Since the old ISA Hardsid is not being sold anymore, I'll publish some
my research work here. I had plans of designing a PCI version of the
with full compatibility with the ISA version. Hard Software has
released their own Hardsid PCI, so my project is now pointless. Well, I
could design my own PCI version, and release the information how to
such a card, but just now I have much more importants things to do.
posting in the CBM hackers mailing list, the Hardsid was originally

To design a PCI version, I first had to know how the original Hardsid

were a mess, so I thought of re-drawing them using a PCB design
At that point I had an interesting idea: I had the schematics on a PCB
