Ar yes I remember the Maxima but wasn't that around 1986? I used the Chromdioxid in 1984 I think that I still have it. I remeber my Aunt having bright orange AGFA cassettes and my Mum brought my a green coloured one from back home in Alicante, Spain!
I loved the Maxell XLII and TDK ADs at the time!!! I wish i'd kept all of my cassettes but I had a huge throw out before I left for University and throw everything away - gutted!!!
Funny how as a kid I had a better sounding system than the one i use now - i've done a full circle with systems and now portability is key, just like my first ever Philips orange mono battery powered record player!!!!
I still have my Grandad's Beogram 1500, Beomaster 1900 and Beocord 1900 with 35 speakers from 1979 in storage! One day...
