- What? Is this another troll? The only things said here that I agree
- with are that ARDI has done a great job on Executor and that we shouldn't
- complain. The more so because ARDI has already indicated it plans to
- suuport OS/2, nothwithstanding the conventional wisdom that only the
- Windows platforms are of any consequence and that all others not only
- can be, but should be, ignored. Windows users need not worry, ARDI
- indicates that it plans to support you, too -- and it will not hurt
- you one bit for ARDI to do something you don't agree with. I care
- nothing for the OS wars, preferring a diverse and competitive market-
- place because I believe it to be both more interesting and better for
- the industry.
-
- ARDI deserves support for many reasons, not least of which is their
- choice to support a diverse marketplace. Still, there's plenty of
- reason to support them even if you don't agree with my diverse market-
- place philosophy. For one, the product is outstanding, with better to
- come. Another is their conduct, or should I say philosophy: they have
- solicited and used the support of their target user community and
- haven't even demanded that we fork over big bucks to get a peak at
- their product. Recently, Cliff allowed as how some $2M has been spent
- with (I gather) little compensating revenue to date, but despite their
- obvious need for cash, they allowed me the educational discount on the
- modest strength of my part-time instructorship at Columbus State
- Community College, a large institution of its type, but no powerhouse
- of computer science, to be sure.
-
- I anticipate that I will be send them more money for some sort of
- cross-platform license for future versions as I actually boot and use
- Win95, OS/2 Warp, and Linux on my home machine.

- Well, I think we can safely say that the answer is no. Not only would
- emulation of the 32 bit flat address space Moto 68K family be difficult,
- if not impossible, to emulate successfully using 64k segments on the
- 286, the emulation of the Moto 32 bit instructions on the 286' 16-bit
- architecture would impose an additional heavy overhead, as well. (O.K.,
- O.K., I know that 68000 had a 24 bit address space not 32, but
- Executor's emulation target is a 68040, anyway, right?).
-
- I may not remember perfectly but 286's topped out a 20MHz or so. Now
- I've successfully run Executor on a 25MHz 386sx, but it was pretty
- leisurely (q12 might be faster, but I no longer have the machine). If
- the address space issues were solved through some scheme for mapping
- the Moto address space into a sheaf of 64k segments and 32 bit
- operations successfully emulated, the result would likely amble along
- at a pace rather slower than "leisurely."
