A correct answer consists of pointing me to a place online or offline
where I can buy a new or used Ektacom HBM-14 intercom nurse-call
console.  Pointing me to a place which has similar equipment is NOT a
correct answer, it must be a genuine HBM-14.  The Ektacom company went
out of business a few years ago.  Thousands of the HBM-14 intercom
consoles were sold to hospitals and nursing homes all across the
world.  Our hospital is in need of a spare HBM-14 console.  We know
there must be many used ones around.  We have not found, nor do we
want an aftermarket replacement, so we expect to find a used genuine
HMB-14.
