I hope Terry doesn't mind (please delete if you do) but I'd like to put in a good word for Ian Mavric of Australia who supplied me this computer. He operates an enthusiast web-site for all things TRS-80, sells many parts and items for them, and he's a real nice guy too!
I should also mention The Classic Computer Shop where I got my Europlus from along with some other parts, and they always arrived speedily and well-packed. Note, being based in The Netherlands it's not a cheap option though!
Again, apologies if this is out of place. I don't have any stake in these guys operations, I'm just a very happy customer.
It's in very good condition, with no faded paint. I haven't turned it on yet - it's American so I need to find my adapter - but I can at least bash on the keys and pretend I'm balancing my cheque-book and storing my kitchen recipes on it.
Just had a watch, and it was good, very clear and informative, though I can see the problems you had videoing the screen contents. I forgot just how good some of the software was for it, as all I saw was mostly the shitty old BASIC games that couldn't run fast enough to do much very interesting. I remember the sound trick though; I seem to remember having to set the tape recorder to sending the mic. input to the speaker somehow so you could hear it, which was a very cool trick when you see/hear it in action for the first time.
