To be honest I didn't do much downloading at all in those days.. Just didn't have the patience for it. If I did do it I would do so over packet radio that I could just leave running all night. I had a third old PC just for that :)

Another reason that I didn't BBS much on my Amiga was that my modem was inside my PC on an ISA card for most of the time I used BBS'es. So I had to run a program on the PC to forward the modem data over a null-modem to the Amiga so either way I couldn't use the PC. So usually my PC was for modem use and the Amiga for other stuff.
