[net.micro.apple] Any DAC/ADC on apple cards??

eklhad@ihnet.UUCP (K. A. Dahlke) (09/07/84)

I have an Apple 2+, and I am interested in playing with sounds.
By playing, I mean at the lowest level.
What I want is a card, compatible with the 2[+EC] open architecture slots,
containing an ADC and a DAC.
I will supply any microphones/speakers/aux input,
provided the jacks are standard.
Let me clarify, I do not want music synthesizers, speech chips, etc.
I only want a raw ADC and DAC.
Is there an apple 2[+EC] card with these devices.
I know it would not be difficult to build one,
but I am not a hardware wizard.
Any leads appreciated.
Thanks in advance.

I bought a pair of John Bell Eng. adc/dac cards and a parallel port board
for about $150 in kit form.  It is about the best system I have found for
the money.  The ad/da's are 8 bits whivh provides enough resolution for
playing around with sounds (adc sample rate is 50 kHz)
	With those components, I have managed to make some digital echo
effects and a few other pretty interesting digital processing sounds.

Check a Byte Magazine for John Bell Engineering's address.
