ScuzzBlog: Diaries December 2018 Entry 30th December 2018: Post 02: Sinclair Spectrum 128 - Salvage Job Sinclair Spectrum 128 - Salvage Job This isn't going to make a whole load of sense but here goes. I have four busted Spectrum 128s the one with the toast rack plus another in an original box. In amongst this is also another Speccy+ which for the sake of the exercise I would just ignore. I test the four loose machines and actually swap out a number to get a fix. I have no idea how I did it but in the end I managed to get all four working albeit each with a keyboard membrane shot. The one machine which was the dummy turned out to have just a dodgy modulator so that also was working. Like I say no idea how that happened. All four now wait a new membrane. Thing is I did acquire a new membrane and in the end fitted that to the Spectrum 128 in the original box. See the next blog. Now all I need to do is save my pennies and get these other 128s kitted out with new membranes. OK... there are only really four machines here that matter and they are numbered accordingly. The bogus Spectrum+ just ignore. I start out a little confusing cus I am swapping out keyboards left right and centre, so the numbering wouldn't make sense. As I progress though I generate numbers for the respective machines. All will become clear.. or not. Probably not. To the pictures .... Spectrum 128 First computer working so swapped out keyboard. Got a little more action on the keys but still missing important keys. This one was much better. Whoops !!! That's not working. OK with two out of the four working with some keyboard action I decided to buy a new membrane and see if I could get one of them functioning. With my four computers now fully reassembled I then checked them each in turn numbering them accordingly. Number 4 Just the dodgy 'y' key. Works sometimes. Number 1 Functioning but with a number of missing keys. Number 3 Same problem with the keyboard. Number 2 Appeared to be well and truthfully broken. Need to go in deep... deep deep. Turned out to be a bad connection on the TV connector. So in the end all four were actually working and needed just new membranes. There may be other issues but nothing can be further checked until I get the keyboards working. That's a tomorrow project. It will happen though. Always does.
