As requested, here are the quick index performance values obtained using the Datafree 16Mhz Accelerator board. My system is a 520ST upgraded to 4 megabytes with the original 1985 tos 1.0 ROMS. Quick Index 1.5 was used with drive C being a 30 Meg Supra harddisk. Settings were Mono, tos 1.0, drive C. No upgrade Datafree board Datafree + Turbost v1.5 ------------ -------------- ----------------------- CPU memory 100 103 103 CPU register 100 102 102 CPU divide 100 185 185 CPU shifts 100 197 197 DMA read 5038 5038 5038 Gemdos I/O 110 118 118 Disk RPM 3604 3604 3604 Bios text 100 126 330 Bios string 100 122 763 Bios scroll 100 115 181 Gem draw 100 120 149 Using applications like ARC, I get about a 35% increase in speed. Spectre (actually Mac programs) for some reason gets a 45-50% increase in speed. - BTW- a blitter socket will get you nothing in return - turbost is as fast and is cheaper - blitters cannot be run at a full 16MHz. Hope this helps /leonard

This makes me wonder what the speed up of PC Ditto I (and/or II) would be. In terms of SI of course...

BTW: Who wrote Quick Index? Is it the same company/person who wrote Quick ST? Steven W. Klassen Computer Science Major University of Waterloo
