Do Alt-r in a workspace -- the cursor changes to a dot, which you can
use to draw whatever forms you wish to use to represent letters (it's
trainable, so you could use the Graffiti forms or any other you would

I would guesstimate that the current VM is probably only about a factor
of two or three larger than a decent assembly language version would be.
The "bloat" really comes from a lot more primitives being added (all the
networking and multimedia stuff for example), along with the
OS-dependent interface code to support it. You can get an idea of what a
1981 vintage VM would contain by comparing it to the Blue Book VM
