So I did some research, and bought the following:

"Trident Instructor Size Underwater Writing Dive Slates", 8" by 10",
US $20 at AMZN:

.<https://www.amazon.com/dp/B0000BZK3Q>

It arrived yesterday.  It is dead simple, being a 8" by 10" piece of
injection-molded white polypropylene 0.100" thick, with a molded-in
surface texture.  

Some of the edges were uncomfortably sharp, so I trimmed them with a
small wood plane, which works very well.  Sharp metalworking files
also work well.  

Polypropylene is not as gummy as polyethylene, so one gets clean curls
or chips from these cutting tools.

The pencil is an ordinary wood-wrapped graphite pencil, which isn't a
real dive-slate pencil; these are available and will fit, but cost
about $5 per unit.

Operational trials to come.

Joe
