While hercules is WAY cool (I've played with it a bit, along with OS/360 since it's "public domain"), it'll never beat the real thing. On my shiny new Dual Athlon 1700+ (1.466GHz) (however I suspect that hercules is only using one processor to decode/execute instructions), I get a Super-Speedy 5MIPS rating at most. While this is about 2x as much as my old Athlon 700 system gave, it's nowhere near as fast as any modern S/390 or zSeries, and probably not even as fast as the S/390 on a card that IBM use to sell with a PS/2 as a P/390. Emulated hardware will _always_ be ages behind the real thing when the two architectures are as difference as PC's and ESA/390 or zArchitecture (not to mention disk I/O, memory I/O, and the mainframe's I/O subsystem in general). -- Pat
