here is my Nicolet Instrument corporation instrument is called 1170 on the front,
model 1174 on the back, plug in module model 171/4 four input signal digitizer,
42cm wide, 32cm height, 64 cm deep including heatsink and knobs, it uses 200 watts, weight 35 kg !!
20 x 2114 ram chips = 10kbytes, 5 x 2901 CPU / ALU chips with their own micro code run its simple software,
serial out done using shift registers and byte to chars converters, all in all a super fun instrument to play with,
this maybe also explain the length of the video. Nicolet corp is from madison wisconsin usa, the year 1978 is written on all circuit boards.
you see it is also full of wirewrap, i think this reveal either prototype, or very low volume, or they are all adjusted to each customers special needs,
anyone know more about this unit ? have seen one ?
