Royalton, VT 05068 > (802) 763-8367 I ordered the "ADC-812", one of two REI products for the M100/102. It's an analog to digital (A/D) board with 8 analog input lines, digitizes to 12 bits, plus sign. I ordered it by phone the middle of last week, and it arrived Saturday by priority mail. REI also sells the "DACQ-SYS", to which Jeff refered above. It's more expensive ($320), but has both A/D, D/A, and digital inputs and outputs, while the ADC-812 is an A/D only. Since I just got it, I can't give a detailed report (I will in the next few weeks), but at first look, it's a pretty nifty system for $144 ($129 for the ADC-812, $10 for the interface cable for my M100, and $5 for shipping and handling). It looks like (he/she/they) gave some good thought to lots of good features, and to making the system as flexible as possible. Conversion time is 1 millisecond, nominally, but this could be reduced to about 100 microseconds by tinkering with the A/D clock. Concise but complete manual includes a complete schematic. Programming examples are in BASIC, but the description of operation is thorough enough to help if you plan to do high-performance assembly work. More soon.
