Dala it's what he has and by no means is it obsolete or antique.
Nismotronic is superior only because of its embedded code (tunercode).
A version of Tunercode was written specifically for the Calum RT and this unlocks all of its potential for the user who cannot program in C. Dave didn't continue development on this so an SA version doesn't exist. I understand that the nismotronic hardware allows Dave to protect his intellectual property and I am all for that. I cannot fault what Dave and John have done for our community, kudos to them.
In circa 2008 when the RT was made it came with; 4 digital inputs, 4 HC(digital outputs) and 4 (0-5v) analog inputs and can hold a 64K rom All these inputs and outputs are on the board so you still can use the ones on the ECU as well. What this means is that it is more versatile worldwide and we are not forced to use a few specific USDM ecus and one expensive worldwide version(GTiR).
Moates decided to save a few cents and use a 32k chip when they made the nismotronic hardware instead of 64k or larger, I would have liked to have seen all these inputs and outputs on the board, maybe a micro-sd slot for logging instead of onboard memory. A direct serial(and or USB host) input to get the real-time and most accurate wideband input. Who is tuning without a wideband? Why resort to 0-5V, what year was that?
In 2016 the Calum RT and nistune are the only viable realtime solutions for the B14 and P11 people that want to keep their car stockish & the appearance of road legal.
In 2016 ppl are still happily using basic boards and are happily paying persons to burn bins onto eeprom chips and send it to them.
Let him use it, learn a bit and then if it doesn't suit his needs, he can take up one of your suggestions, to dismiss the Calum RT as being an antique is unfair and untrue, to say the least.
If english was his first language he would have had this running since the first reply.
