Atari ST Monitor?

[xenophon <xenophon@online.nospam>]

Back when I had a tricked-out IIGS, I got an Atari ST monitor from
somwehere and used it with my system. IIRC, the monitor was an inch
larger than the stock Apple monitor, and it had audio built-in.

1. Was this a stock Atari monitor, or was ti modified (I think the
cable was modified)?

2. Did anyone else have one of these?

3. Does anyone know where one could be had these days?

Thanks.
