ISA-cards CAN be used with Amiga:
- there is ateo-bus which is just ISA with a different name
- there were the Domino and Omnibus GFX-cards, which were really just adapters for ISA-ET4000-VGA cards.
- there still is the XSurf doing the same trick for ethernet
- if you have an C=-bridgeboard some ISA-cards can be made useable for the Amiga-side
And offcourse not to forget:
- the famous DIY OMTI-Adapters, featuring an 8Bit-slot for the use with old HD-controllers :roll:
