[GreenKeys] Heavy Metal Usage in the Deaf Community

[Jordan Spencer Cunningham]

Hi all,

I know that some of the old machines (M15, M19, probably M28, probably
others) were used by the deaf community back before the smaller, less
expensive machines were manufactured specifically for deaf use over POTS
(TDDs).

I'm just curious-- do we have any deaf on the list here? And does anyone
know how common this was back in the day? I've guessed it probably wasn't
extremely common in the community due to the expense, additional equipment
required to use over POTS, and the significant maintenance and learning
threshold, but I really don't know for sure.
