Look around for (Dave) Hagelbarger and Cardiac. "Cardiac"
was the reasonably-clever name, given the early propensity
for computer names ending in "-ac" for automatic computer,
but of course makes searching more subtle if you're not

for pictures.  Don't know whether the company mentioned
there still stocks them; a friend did get one a while ago.
