Hi,
I am new to this forum purely because I was unaware of any Aquarius collectors. It's good to see things move on, I can remember when I had my Aquarius over 20 years ago, programming machine code in decimal (no assembler's to hand then). I had a go with the emulator yesterday and it all came flooding back, good work. I wrote Aquapede back then, but it didn't sell in great number's as the Aquarius's life was pretty short. It's possible a copy still exist's at my parents house and if so I will make it available to all. Mattel or Radofin were very good to me then by giving me all the tech info on the machine which made the job a bit easier. If memory serves me correctly, taking into account the memory constraint's I had to work with, movements were done using screen memory scans and moving characters either left or right or up and down and a storage area for the screen so I could replace the items under moving characters, All good fun. It would be good to see it again. I also modified a zx81 memory expansion to fit my aquarius. It wasn't at all elegant but done the job. I didn't mind that the Aquarius wasn't high res, but user definable character set would have made a difference. I always remembered it as a solid reliable machine and quite a lot of fun at the time. I am following this thread with great interest and will probably have a go at programming z80 code again. Keep up the good work.
