You can now have four of each of those. And the MNCAD has been expanded to the maximum of 64 single-ended channels &#8211; well, theoretical channels, because until something is hooked up to them, in reality it is just a multiplexer. The lowest 8 or so channels are used for the A\/D components on the boards, everything above that is available &#8211; for instance for sensor components. <\/p>\n\n\n\n<p>In a &#8216;real&#8217; MINC, there were only 8 slots for modules, and for 64 A\/D channels you would already have used half of those &#8211; you&#8217;d need three MNCAM multiplexers next to the MNCAD itself. But in the PDP2011 MINC, there is no limit to the number of slots &#8211; you can configure everything at the same time. So I think I can claim having the biggest MINC system ever &#8211; with 2 MNCKW clock modules, 4 MNCDI digital input modules, 4 MNCDO digital output modules, 4 MNCAA D\/A converter modules, and the equivalent of 4 modules for A\/D. Over two times as many slots as there were in a real MINC &#8211; but still the software works flawlessly.
