Some comments from the Project Manager.....
HI. I thought I would provide a bit of feedback having been in the middle of it all at the time at Acorn. First a great article and factually pretty near the mark. Yes, Arthur 0.2 was in EPROM and we thought we would have them back as they were expensive and possibly re-useable. We set a very firm date for the launch, June 1987 if I remember and hence the OS was whatever state it had reached; not an ideal approach but it would have been sad to have left the superb hardware waiting for too long. Were Acorn products over-priced? No, the profit margin was reasonable bearing in mind the high level of R&D and the high technology. PC clones at the time were sold at very tight margins and made in the Far East or under railway arches in the UK with virtually no R&D spend as a result of the vast volumes. When I look back at Acorn Marketing it was some of the best I have ever come across in my career both before and after. Acorn made the best of being a niche player and inevitably struggled just as Apple did for a long time. Someone comments that Archimedes had 'Windows emulation'. No it didn't, it had genuine MS-DOS licences provided by Microsoft. It was the hardware that needed some emulation as many PC applications at the time wrote directly to the PC hardware bypassing MS-DOS much of the time (it was just a Disk Operating System after all not a Machine Operating System as in Acorn products). Finally as someone else has commented acronyms should always be in upper-case so it should be ROM not Rom etc. Why UK journalism insists on treating acronyms in this way when the USA gets it right is beyond me; it makes speed scanning of technical articles more difficult as I always scan for the techno words. So when RISC-OS was developed and launched it was all upper-case and never anything else; rant over :-)
