is there an x86 educational simulator?

[Daniel Simon]

Has anyone ever written an educational simulator that will execute x86
(preferably at least 386) code one step at a time with a visual
representation of all the registers on the screen so thick headed
newbies like me can figure out what all those codes are actually
doing? Maybe something with a pretend memory array and a couple fake
i/o devices to excersise?

Recently I saw this: http://www.geocities.com/emu8086/
It's an 8086, but looks primising.

Bochs (http://bochs.sourceforge.net/) simulates the CPU, video board,
and other devices. If you get the version with the built-in debugger,
you can set breakpoints, examine memory and registers, etc.

Last time I checked, however, it did NOT have an easy-to-use GUI
interface -- just an awful, cryptic GDB-like command line UI.
Maybe there's a front-end or GUI for it now...?

the Ketman something or other it was discussed in this newsgroup a
while back so there may be a URL

Thanks for all the responses. I played with the Ketman
tutorial, which looks like it will go a long way in helping
me visualize what happens when x86 instructions execute,
which is what I was looking for.

My first attempt to install emu8086 kept giving me some
missing ocx file error, I will try to work around that and
run the program when I have time.

I still hope to find something that models a 32 bit
processor eventually.

Thanks again,
Dan
