- Ouch. That's sad. From a performance experience, Executor on an
- entry level Pentium easily outperforms an LC475. Executor doesn't
- have the degree of compatibility that MAE has, but that's due to us
- not having access to (or having looked at) the ROM and Toolbox source.
- Feel free to check a demo version of Executor from our web site
- http://www.ardi.com. Executor only runs on x86 currently, but that
- will change.

- Emulating RISC on RISC *shouldn't* be a development nightmare, nor
- should performance suck. Check out ftp://ftp.ardi.com/pub/SynPaper to
- see how Syn68k, our current generation of synthetic CPU, works. Mat
- Hostetter has already done significant work on a successor to Syn68k
- that will be able to support PowerPC emulation on SPARCs with greater
- performance than we currently get (there might be some alignment
- slowdowns but there'd be no byte swapping, less register contention
- and a much more sophisticated dynamic translator).
-
- I've sent followups to comp.emulators.mac.executor.
