Biggest MINC ever!

Over the past few weeks I’ve been doing some finishing touches to the MINC, and one of the things I’ve changed is the configuration of the MNCDI, MNCDO and MNCAA modules. You can now have four of each of those. And the MNCAD has been expanded to the maximum of 64 single-ended channels – 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 – for instance for sensor components.

In a ‘real’ MINC, there were only 8 slots for modules, and for 64 A/D channels you would already have used half of those – you’d need three MNCAM multiplexers next to the MNCAD itself. But in the PDP2011 MINC, there is no limit to the number of slots – you can configure everything at the same time. So I think I can claim having the biggest MINC system ever – 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 – but still the software works flawlessly. As witnessed by the output of the VMNF test program:

Meantime I’m finishing up some bug fixes and a couple of new features, if it keeps on raining in The Netherlands there will be a new release on the download page soon!
