Bob Pease seems to be a technological dinosaur, with a pathological hatred of computers, and SPICE in particular! Though to be fair, he obviously grew up with SPICE when it was in its infancy, and so would have suffered all its teething pains etc. He should try something like SIMetrix, which is what I have: it is not SPICE per se, but based on SPICE and heavily modified, so many of the model discontinuities and convergence problems are a thing of the past. But we can't all be born analog gurus, some of us have to work hard for an even meagre understanding, and as far as I'm concerned, SPICE is a tool like any other: use it well, and you'll reap the rewards; abuse it and watch out! As a tool to *aid* understanding, and not to *replace* understanding, is where Pease seems to have it wrong, in my view.
I've sent a polite enough request to On Semi asking about old SPICE models, but I shan't be holding my breath that they even acknowledge it (filling the 'required' field for 'company name' is always gonna be a killer!).
