Actually, I get the impression that Insignia have spent most of their money chasing the Windows API, but I could be wrong there. Nevertheless, it is worth observing that the Hedley emulator (186) was written in less than a year by basically one person, and works more than adequately well 8) > You'd have better luck building 'translator' code that changes the x86 > opcodes into native instructions on each platform, which DEC and IBM > have done. ARDI do that too; I seem to recall they actually published a paper on the topic. Of course the 68000 is a much more rational processor to emulate 8) > Nate -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
