I can assure you the DraCo never used Paula, it used a modified Tocatta soundcard.
Quite... But no one was talking about audio, Paula is a very specific and unusual interrupt controller (which AmigaOS relies on)... Though I can imagine that it would be quite easy to handle that aspect with off the shelf parts.
Cia chips, are not custom chips, but generic 68000 auxiliary chips sold at electronic shops.
Pop down to Maplin and pick me up a dozen MOS6526s cheers... Oh wait the company that made them went bankrupt in 1994... That's sucks, if only I could remember the name of that company...
Do your research

And kickstart roms are nothing more than eeproms/proms that you can probably buy at your local electronics shop.
So you see the DraCo had no custom Amiga chipset at all. They relied on a heavily modified kickstart, that was patched upon boot.
True.
