man I feel sorry for you.. really do :)

I actually still play some C64 games now and then (emulated) never seen a
C128 upclose, but I dare to say that nothing ever invented was better then
the C64...

no pentium can even come close to the horse power squeezed into such a tiny
machine, running on less then 1 mhz, yet being able to do all graphic tricks
of a PC.. even the 16color (hardware limited and palette set) could be
fooled into more then 16 colors.

and don't even get me started on its musical powers... oh man, memories :)
