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. -- Karl Dahlke ihnp4!ihnet!eklhad

#R:ihnet:-16000:uiucdcsb:4600008:000:489 uiucdcsb!thielges Sep 9 11:39:00 1984 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. Bart Thielges
