The only scanner I've ever used on an Amiga is a Power Hand Scanner (B/W) which connects to the parallel port. It's been mothballed for over 15 years, but I remember having to scan images in strips and join them using Power's scanning software package. Scanning and editing the images was a slow and painstaking experience, yet the results produced, gave a great sense of achievement and it was (perversely) great fun too!
Nowadays (on a PC) it's all too easy!
