but then did Sega want to do an 'Amiga Killer'?
its my limited understanding that Sega used Amigas for Genesis/megadrive development work.
The Sega dev kit being a hardware dongle that plugged into the sideport of the A500, and allowed programming of cartridge eproms, and running stuff.
quite if it allowed you to run say, sonic the hedgehog on an A500 i wouldn't know... ;-)
