NT4 was x86, PPC, MIPS and Alpha on the disc I had. There was also an early beta of 2000 for Alpha. Don't know what you mean by Alpha 32- I thought the Alpha was the 64-bit replacement for the VAX.
was as a kid in a cybercafe (back when those were a thing) for half an hour at a time. First time at home was when me and my dad installed an internal modem dug out of a box of random parts (turned out to be something silly like 9600) and signed up using a Freeserve CD.
