 I am slowly re-entering the world of assembly programming and am confronted
with 2 different methods to program graphics on the Amiga in assembly.

 I have books that deal directly with the copper and those that deal with
the graphics library in ROM.

 Besides the fact that my programs will probably not be compatible with the
new Amigas (I use a 500 with 1.3 and old chipset), will the speed difference
really affect me? In assembly?

 Thanks

I started using the Library routines for graphics , but they where
to slow.

The speed difference will affect you , but it depends what you want.
I wanted lots of graphics along with smooth scrolling all in one 
display.For this the Rom routines where useless.

!Yeah there is a *BIG* speed difference, if you want a larf, have a go with
!some of the gfx.library's bob functions. (Go for a cuppa when you sort a bob
!list.)

Better still , try scrolling a viewport ... The colour flickering
is rather amazing !
