VLSI made the ARM2 and chipset available in early 1987. I seriously considered using that in a machine I was designing instead of the 68020. But I had been burned by Motorola announcing chips and then cancelling them when almost nobody used them (an update of the TRS-80 Color Computer chipset that could be used with the 6809 or 68000) so I decided to continue with the 68020 until somebody else came out with an ARM product. Acorn launched the Archimedes at the end of 1987 and I bought the chips and the manuals and wrote an ARM assembler and simulator. But the project was frozen and I only actually built the machine in 1992 though the chips were obsolete by then. http://www.smalltalk.org.br/fotos/casa3.jpg http://www.smalltalk.org.br/fotos/casa3.jpg While the chips were indeed created specifically for the Archimedes, it would have been possible for some other company to have made a machine with them before Acorn.
