Distribution: usa Date: Sat, 21 Nov 92 18:48:49 GMT Lines: 29 Attention: the following may be common knowledge, but assuming that everyone else is as ignorant as i am... Here's how to make a sound sampler for your GS, reeeel easy. I notice that many companies are charging $50 and upwards for digitizing cards. This is a total ripoff. To make a sampler to receive input from a tape player, CD player, whatever, all you need is: 1 1/8" phono jack. This is the same size as on walkmen. 1 molex connector 2 molex sockets. these can perhaps be bought at Radio Shack. My helpful sales representative directed me to the rack of nylon powerplugs. oh well. if you can't find 'em use something else instead. try IC sockets. 2 long pieces of wire here's what you do: open your computer. notice the little brown 7-pin connector at the front. this is the sound expansion port. you can also use it make a stereo o maybe 8-channel surround sound expander. notice the pins. the pin in the front is the analog-to-digital pin. the pin next to it is the ground pin. connet pin 1 to the '+' lug on the phono jack. this is the small one. if you have a stereo one, solder both small lugs together. connect pin 2 to the ground lug. this is the big one. there, that's all. now find some good sampling software. and send me a copy because i need it too. ben Newsgroups: comp.sys.apple2 Path: news.weeg.uiowa.edu!news.uiowa.edu!uunet!zaphod.mps.ohio-state.edu!sol.ctr.columbia.edu!news.unomaha.edu!slab.slip.uiuc.edu!derek From: derek@slab.slip.uiuc.edu (Derek Taubert) Subject: Re: IIGS sound sampler!

But what you fail to mention here is that any bad signal or spike that you may feed into this circuit will completely blow up your Ensoniq chip. Unless you've got "connections" and can order one directly from the company, you're looking at a motherboard swap to fix this. Oops. What you get for your $50: a cheap REPLACEABLE op-amp that will happily die in place of the Ensoniq when you decide to feed it a really nasty signal. One more thing that you should at least do if you haven't listened to me, is to add a capacitor in series with the signal input so that you can get rid of DC offsets. This is what killed mine when I did the exact same thing a few years back. Take my advice, it's REALLY not fun trying to get ahold of a new Ensoniq chip. Derek
