|  Re: A mathematical demo
Thanks again. I missed this emulator. It has Linux port and I use it. The test gives a bit surprising result - only 8.2 secs for 1000 digits - it is faster than SuperCPU. The explanation is easy - 80286 division is 7 times faster that at 8088. However I am not sure about exactness of this emulator. IMHO it is faster than iron AT.
[UPDATE]
Thank to RobertB :) I've made a SuperCPU version of this demo. It works in the native 16 bit mode. It looks like the native mode program maybe upto 100% shorter and upto 50% faster than the program for the emulated (C64) mode. My aim was to write a code which will be faster than for IBM PC AT 6 MHz. I couldn't reach it. :( 80286 has too fast hardware division.

BTW SuperCPU shows itself as about 21 times faster C64. It is the amazing piece of hardware! If c264 line was a bit happier then such things would be made for +4 too...
