Acorn IEEE488 interface

I remember your message on the BBC list about this, and had a *really* vague recollection at the time of seeing something to do with the unit a while back amongst piles of other stuff. I had absolutely no idea where it'd be though - assuming I hadn't imagined it anyway (and that it was even something useful). Then I went and spotted the darn thing on top of a pile of to-be-sorted Acorn stuff about an hour ago - so good timing on a second posting here! It's 86 pages including covers, but it is A5 size, so I could try and scan it at two pages per scan on my A4 scanner sometime - not sure if I'll get chance this side of Christmas, although I can try.... Oh, I probably already have a scan of the Acorn advertising for the unit too (it'll just be an A4 page), although I'm surprised that's not already out there in electronic form. I've also got the schematic for the Acorn System IEEE488 card somewhere - it wouldn't surprise me if the BBC unit is based heavily on this (I don't think I have the actual BBC version's schematics though, although I'll check) I don't think they were widely used. I suppose the BBC micro came with enough expansion options that most people had no need for it. Cambridge university still had one as of last year, but I'm not sure what's happened to it since or if there was any software with it (almost certainly not; hardware from there seems to usually get thrown out separately to software / manuals). This was heard via someone else, so I'm not even sure who the contact there was. Kent uni almost certainly used to have one too, as that's where my Teletext adapter came from - with an IEEE488 box lid! I've also got a complete unit in the cupboard (but no BBC-side ROM to go with it) I *think* Tony Duell (on this list) has one too. Other than that, those are the only four (well, three and a lid) I've ever heard of. cheers Jules
