A full Spectrum of emotions

[rubber_jonnie]

Both Z80s are good and the soak tests worked fine, I just need to fix the 'muddy' colours, which the manual suggests is an issue with TR2.

But not now, back to bed, see if I can sleep at all.

I think it's the lack of sleep which causes the biggest problem for me.
Get better soon!

And for me. I had virtually none last night, and although I did get some this afternoon, it wasn't much.

Yes, a good rest is a must when you are ill.

So a day without tinkering with your retro stuff will be very helpful for you.

It's been kind of forced on me, I just had to go to bed, felt so awful. Up, showered and dressed today, but it only made me feel better briefly, wanting to go back to bed now...

I understand you...

Feeling better this morning, so after I found a new PSU for the CPC, I had a look at the original Spectrum + board to try and figure out what the video issue was. A bit of scoping and all the signals looked good at the LM1889, so I then wondered if there was a cold joint on one of the CHROMA pins where I'd removed the LM1889 and fitted the socket.

It turns out there wasn't, but I noticed pin 1 looked like the track over to C39 had a break. Sure enough, doing a buzz test and cross referencing to my spare board, and there was indeed a break, but very difficult to see. I can only assume I did it desoldering the LM, it's a super fine track, so it wouldn't take much.

And it is working again. The + is now reassembled and running a soak test:

So far all good EDIT - 0ver 200 iterations later and all is well.

So it looks like this is the end of the Spectrum saga. I thought it would be just the one machine to begin with, but it ended up as 3. As a bonus, I now have a fully working spares board just in case, that turned up dead from eBay (I expected it to be dead) and I was able to revive.

It really has been a full Spectrum of emotions!!!

On a side note, doing all this stuff this morning has just made me feel ill again, so back to bed for me, at least I can write this and then go have a nap...

@rubber_jonnie Glad that you are starting to feel better. The lack of energy is what's causing me the most problems too, so hope you get a good rest!

Good news on the health front, for both you and the speccy.

Thanks. In bed now after lunch, very tired despite sleeping well last night.
