| G3 Desktop sound card |
Posted by: jamie marchant on 2014-12-19 09:31:13
While taking apart a G3 Desktop I realized it uses an interesting sound board which I thought I would share here.(personally I find the modular nature of this board facantaing)

What I found interesting is the number of expansions. I found some documentation on-line that says that the white 'AIO' connector would be for a board that had RCA jacks and a phonojack on it. I'm not sure how useful this would be.(since you can get adapters for that). The black plug would be for a capture expansion(PCI card?) and the long brown(ISA?) connector would be for a modem?
Now I'm curious and wonder does anyone know:
- What the sorter pad next to the capture input would be for?
- Wether the modem port was actually for a modem or was it to capture and record phone calls?
- Is the modem card ISA? If so could you put something else in the slot?
- Would the capture card go in a PCI slot?
- How expensive where all these addons back in the day?
- Is the edge connector of the card itself proprietary or some sort of standard?

Do you know this Apple document?

This is a description of the optional AV card. But I don't know if it's the same as installed in some 7600/8600/9600 Powermacs.
BTW the brown connector cannot be an ISA or PCI slot because there is no room left for a typical card. And: ISA slots use different spacing, PCI slots use different number of contacts, AFAIK.

So the brown card must be strictly a modem card. That AV card would be the one for the G3 Desktop. Looks like it would be handy for it's time.

It's usually referred to as the personality card. It only fits in the beige G3s. The brown slot is for a modem. There were 3 or 4 different ones with that one being the most common.
