Strangely enough I've reading this using a 166MHz Pentium
with 168MB of RAM.

"i8254" frequency 1193182 Hz

I've not got round to upgrading the operating system due to
incompetence and ill health.
Is that enough to run lisp?
Well, I installed an up to date operating system on a more
powerful machine during a window of good health

It seems plenty fast enough. I wrote some code for music
synthesis, direct algorithmic synthesis, with each sample
computed by Lisp code, and it runs in real time.
Also, my crude 3D viewer code rotates simple wire frames in
real time.

(and could work much better, I've a X event backlog problem
that I now know how to fix.)
Unfortunately I cannot tell whether my comments are really
helpful to the original poster because I'm using fvwm2 as my
window manager. I've not burdened my old machines with a
``desk top''. If a modern desk top is essential for 7 to 12
year olds then I don't know.
For older children, who can type commands into an xterm,
crappy old machines, even worse than Pentium III, are
perfectly usable. They are much more powerful than people
now-a-days realise, it is just a matter of dodging those
particular programs that throw it all away.
