What's that Placa thing? It says it's some kind of audio processor but it's some kind of giant breakout connector on the back.
After looking it up, it's an Argentinian soundcard from Audiocom. ADX 925X from 1996. I'll quote the page I'm reading. Kinda interesting.
"The Audicom cards are a family of PC audio cards developed by Solidyne. They were intended for the broadcasting market and some models included the Audicom broadcasting system.
In mid 80's Solidyne, a broadcast manufacturer company, started the project of recording audio in a PC to automate the spots emission (at that time done by cartridges). By that time, the hard disk were very expensive and extremely small (a PC hard drive allowed 10MBytes of storage), so the engineers knew that they needed to develop a system to reduce the required bits as much as possible in order to be successful. The result was the ECAM audio system, the first system was showed to the 'Secretaria de Ciencia y Tecnica de la Nacion de la Republica Argentina' in 1988.

Edit: Hold on Audiocoms wiki page says "Audicom was the first system in the world to record and play audio from a PC computer, beginning in 1988 the era of digital recording that would eliminate recorders from magnetic and cassette tape used for half a century".

I'm in no way an audio expert, but is this true? 1988 sounds very late to me.
