Hi all, Mostly copied over from qlforum.co.uk, so if you read it there, sorry for the redundancy!
Today I ran a loop on an unexpanded QL in monitor mode (US model, has weird interrupts) and then with a 68EC020, a GC and a SGC. 100 PRINT DATE$ 110 FOR loop = 0 to 100000 : NEXT loop 120 PRINT DATE$ It's a good timewaster. It just moves things around, takes a certain amount of time. Machine Time Bare QL 2m17s My 14MHz EC020 1m01s My 020+RAM 0m39s Gold Card 0m29s Super Gold Card 0m12s My first line is an MC68EC020 running just pure QL hardware. I can't get it reliable above 14MHz so that was the speed for the test. My second, faster line is with 512MB of 16-bit SRAM added, and a simple PAL address decoder that allows the 020 to access the memory in its native width. Rounding off, with QL = 1, basic 020@14MHz = 2.3, 020+RAM = 3.5, GC = 4.8, SGC = 12.5 So I have a little way to go, I think. However, 2.3x achieved by around £40 of components is... nifty. If this gets people wildly excited, I'll write up a how-to and a schematic Dave _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
