The following would be a viable solution for this application:
4 x TC-08
(8 channel thermocouple converters)
1 x ADC-11/12
(11 channel 0-2.5V converter)
The laptop will most likely have a parallel port connector for the ADC-11, however, it will not have enough serial ports for the TC-08s (they require one each). We can supply USB to serial port converters
for any additional ports you require (I believe you need Win98 to use USB though).
Notice that the ADC-11 only has 0-2.5V inputs, so if you require 0-10V you will need to use a potential divider which you can buy from any electronics component vendor (or make yourself if you know how).
The ADC-11 will measure the high and low of digital signals against time, but it will not decode the signals.
I hope this helps.
