So at the time, to compile software for Windows NT Alpha, was there an Alpha IDE and compiler available (something like VC++) such that developers were writing and debugging locally, or would developers usually cross-compile from an x86 machine?
To answer my own question, now that I'm not on my mobile: it looks like there was an Alpha version of Visual C++ 2.0, as well as a cross-compiler for the 68k Macintosh! [1] I was firmly in VB land at the time (as a ~10 year old) so this bit of history eluded me.
