My first Amiga was an A1000 which I bought when KS & WB 1.1 was first released.
I got an A4000 in 1998 and proceeded to Tower it, I was later given a none working A4000 which I was able to fix.
Most of my amiga need are now met by using Amiga Forever and some testing of AROS.
Although I just got a Voodoo4 card so will test on my A4000 Tower when I get the time.
