I was an Atari 8-bit user back in the mid-80's and was feeling the pressure from the Atari scene back then to upgrade to the Atari ST, however I just wasn't really wowed by any of the ST demos, apps, or games that I'd seen at the time.
One day I remember walking into an Electronics Boutique store in my local shopping mall and seeing what to me was the "Holy Grail" of gaming acheivements back then - a port of Dragon's Lair that captured the visual style of the arcade game (unlike the Coleco Adam and C=64 versions that took many liberties due to hardware constraints).
Utlitmately I opted to stick with my Atari 800XL for BBSing and gravitated towards the NES for gaming, but I would sell both systems in a few years to support my newly found interest in guitars. After I got out of high school in the early 90's I met musican and Amiga enthusiast through a local BBS and he introduced me to OctaMED 4. I bought a used A500 and 1084 for about $150, discovered that 512K of RAM wasn't enough for MED, and bought a trapdoor memory/clock expansion. Unfortunately the first card I bought only had a working clock, so I exchanged it for a card out of one of their floor model A500s (ironically the clock didn't work on this card).
I spent most of the 90's composing on OctaMED, gradually upgrading to a sidecar hard drive, then to an A3000, then to an A4000 with a notoriously bad Buster chip, and finally to an A1200 tower setup before a brief fling with an Amithlon setup. Although my fondest Amiga music memory was of the CDTV that I placed in a rack and used to gig with. We'd fit and entire scripted setlist (the startup-sequence loaded an IFF image of our band logo and our setlist, awaited a button press from the remote, loaded each song - decompressed with powerpacker lib - and played via the MEDplayer) on a single 880KB floppy. It impressed a lot of people in the late 90s. Those were great times. :-)
