I happen to have a large number of machines that are old and some are even
slow. They do many jobs becuase if for anything else they work well.
Now by current standard a z80 at 4mhz is positively glacial but it runs
the best software for docs that I happen to like (runoff).

I've done this with a MVII to teach Pascal to a small class (12) on DHV11s
and it wasn't even straining and I still had 4 spare terminal lines unused.
Another class used a MVII and 8 VT1200 xterms running decwindows back when
PCs were hot if you had a 486dx/33 and 8mb ram running Win3.1.

They are kinda neat. I have 11s and 8s as well. I happen to like the
PDP-8 for it's minimalist instruction set.
