I bought this a few years back and thought it about time I actually look at getting it running. This was supposed to be a nice, simple job on the run up to Christmas however it has turned out to be a total nightmare. My NAS failed and a large number of the files were corrupted. I've managed to save the majority of them, however some are beyond recovery. In total, I've spend weeks recovering this and I hope you feel it's worth it. Oh, and it was released in 1982, NOT 1992 as I incorrectly said at 02:55 !
