For no particularly strong reasons; I had working QBUS machines, and
prototyping cards, etc, etc.

Thanks. Feeling good today after a bit of frustration with development
not going faster.

I did implement that too. Unix doesn't need it but I had to fill the
block with something and it wasn't that har

and writes after all and I hadn't implemented those yet. We're running
this on an
