I'm currently looking into the BBC Micro's history in Australia (and there's quite some history!), and I stumbled upon a couple of uncited claims on Wikipedia in relation to the development of DFS and Econet for the Beeb.
On Econet:In 1981, the Education Departments of Western Australia and South Australia announced joint tenders calling for the supply of personal computers to their schools. Acorn's Australian computer distributor, Barson Computers, convinced Joint Managing Directors Hermann Hauser and Chris Curry to allow the soon to be released Acorn BBC Microcomputer to be offered with disk storage as part of the bundle. They agreed on condition that Barson adapted the Acorn DFS from the System 2 without assistance from Acorn as they had no resources available. This required some minor hardware and software changes to make the DFS compatible with the BBC Micro.
I have confirmed that the Tasmanian, South Australian and Western Australian education departments entered into a computer education alliance in the early '80s in order to share curriculum resources and software. Further research suggests that the BBC Micro was adopted as the preferred platform between these states. Whilst I couldn't find a direct reference to any joint tenders made, there's enough circumstantial evidence to imply that this probably happened.In 1982, the Tasmania Department of Education requested a tender for the supply of personal computers to their schools. Earlier that year Barson Computers, Acorn's Australian computer distributor, had released the BBC Microcomputer with floppy disc storage as part of a bundle. Acorn's Hermann Hauser and Chris Curry agreed to allow it to be also offered with Econet fitted, as they had previously done with the disc interface. As previously with the Disc Filing System, they stipulated that Barson would need to adapt the network filing system from the System 2 without assistance from Acorn. Barson's engineers applied a few modifications to fix bugs on the early BBC Micro motherboards, which were adopted by Acorn in later releases.
Whilst I found some interesting nuggets about Barson and their relationship with Acorn, I can't find anything directly connecting Barson with the development of DFS and/or Econet implementations on the Beeb, nor can I find anything to back up the claim that Barson's engineers were involved with bugfixes on Beeb motherboards. However, I've seen a few posts on here about hardware (expansions, adapters etc) made by Barson, which suggests to me that they had the capability to adapt DFS and/or Econet for the Beeb from the System 2 as claimed.
As such, I'm inclined to believe Wikipedia in this instance ... but I can't really cite Wikipedia, if that makes sense.
If anyone knows a bit more about the Acorn/Barson connection, particularly in relation to any hardware stuff that Barson may have been involved with, I'd love to hear about it. Many thanks in advance.
