I recall a web site that legally hosted disk images of original install disks for obsolete Amiga hardware, but I don't recall the URL since it's been so long.
An Internet search should turn it up....
[Edit]
;-) Oh, wait;
here it is!
Also, I recall that the TrumpCard insists upon its boot drive being named TCBoot:, and will choke if you rename it to DH0: or anything else sensible. So, you're stuck with their choice. Still, if it boots from hard drive instead of floppy, what's to complain about, eh?
Good luck, and have fun!
