System: Colour Mega 2, TOS 1.4 (RAM)

Test conducted with QUICK Index. The CPU and drive tests where ignored
as I was concerned more with screen performance with and without the
blitter and with QUICK ST active/deactive.


Blitter		QUICK ST	BIOS	BIOS	Scroll	GEM
				Text	String
----------------------------------------------------------
no		no		98	98	100	99
yes		no		106	103	130	128
no		yes		140	427	127	108
yes		yes		140	427	127	146


From what Darek has told me, QUICK ST is self-modifying assembler code
that does what the C written TOS code does. What I don't understand is
why the scroll test is a tad slower with QUICK ST on. The blitter does
improve graphics speed on the Mega. But with QUICK ST and a blitter we
can see that graphics could be faster still.
