There was a place called MBV? Computer Supplies in Dorset rd Croydon. It was always so busy, basically had to serve yourself and then line up. But if you were willing to wait they'd look after you.
Another was Pacific Micro Labs in Elizabeth St City which was a grab the box and pay place, and the third was in Nicholson St in Abbotsford, but cant remember its name. I bought my A2000 there in 1989 and quite a bit of software at different times. Always a great help. I remember one guy spending half an hour showing me how to use both samples and midi in Dr T's Tiger Cub.
I see the same kind of "spirit" in Mac shops. But the detail in the conversations is missing.
