I think this one will be:

ONLINE COMPUTER SYS. INC 8 BIT DSP AUDIO BOARD PULLED FROM AT&T 6386 /25 WGS

according to

http://www.ambry.com/C5081.html

In looking around, it seemed like there were a bunch of copies of the ebay text. I wonder if various aggregators are copying ebay buy it now items, marking up a crazy price, then if you buy it from them, they go and buy it from ebay and pocket the difference. Another theory is this ebay seller just copied HIS text from one of those other sites. Either way, there doesn't seem to be much real info.

My guess is that it is a special purpose DSP board that you can program with various processing.. if you knew how to interface to it. I knew a guy who used such a board for room reverb processing on an ancient 486. Back then, the DSP chips would blow away regular CPUs for audio processing.

Its hard to say due to the as-usual awful Ebay photos.. seriously, if these guys would take a decent picture, and describe the item well, they'd make a lot more money.

Let us know when you get it. Find the most expensive looking chip and thats the best teller 😀 The big socketed one may be a CPLD, if it is that doens't tell much. I'd look for a TI DSP chip on there. Unfortunately, I doubt this thing is set up as a SB compatible or anything else you can easily use.

hi

in the 90s i worked with some cards made by
dialogic. at a guess this card is similar, yet
probably even older, in that it was designed
for a specific purpose other than audio playback
and more likely something to do with
telecommunications.

bye

Thanks to everyone, when the card is here I will tell the details.

See ya!

The computer that card shipped in has some mention in an old late 1980s issue of Network World Magazine. They advertised said computer as being notable for having the ability to answer a phone.

Thanks to everyone to the replies, but I do not think that my card is the one from the google books, take a look in this auction from ebay: http://www.ebay.com/itm/AT-T-6386-25-WGS-Voic … ht_14195wt_1042

for me, this computer have these answering phones cards. I bet this card is another type...

but thank you, great info!

I can bet you that this card in the end will be a paperweight to you. Not only it is suspiciously looking like a telecoms card but it will not even function as a sound card.
edit: I just saw the original auction too, this won't be of any use to your XT machine....

Yeah, I'm afraid that too, maybe I sell her here in Brazil, as "piece of history"...

Man, this looks pretty cool. Please let us know how if you can test it. Mandou muito bem! 😉

the board is finally here, two notable chips:

one pretty fast (40MHz) 68 pin TMS320C25FNL, and one Bios looking PCM54HPJ 28 pin... 4 RCA jacks, labeled IN1,IN2,OUT,SPKR.

Full size ISA card.

Any clues? Any software to discover the card?

thanks!
