Both drives were connect to the A2091 card.
So it sounds like the card was used for MS Dos.
Unless I mis-understand the docs, there should be a
rom image in Devs, but I'm not finding it.
How do I get it to boot up ?
After reading the docs, it sounds like it could be an
interesting card, possibily being able to do selectable
booting (Apple or MS Dos).
