An Obvious RAM Fault? Toastrack Repair with Suspect Ram
Вставка
- Опубліковано 27 сер 2024
- A Sinclair ZX Spectrum 128k "Toastrack" has a suspiciously familiar looking fault. Sent to me by Paul Universal Retro Boss my immediate thought is the ram is faulty. Normally this leads to the conclusion that something else entirely different is wrong! But this time I might just be right!
Fixing stuff is FUN!

I'm glad you listened to me when I said at the screen "Don't forget to test the new chips before you install them!"
Bovinely spectacular!
Cowabunga!
I'm offended the extra unnecessary mooooooo!! at the end was not required. LMAO awesome video as always Lee :)...
Mooo sorry! (is that a pun?)
The great thing about a thermal camera is that if a component is abnormally hot then it will drown out the components with normal temperatures. So the whole screen will be blue or darker and the faulty component(s) the only orange on screen.
Fun video! I will solder my ByteDelight test cartridge this weekend and use it on my two Spectrums with corrupted video output, and I will no doubt find out that faulty RAM ICs are the cause of the problems...
I agree, I often wonder about diluting my content by filming myself fixing other random items, but I just enjoy it.
You make the random a feature though!
im really tight it seems.. i didnt have kapton tape and didnt want to buy any... so i just used kitchen foil ! Folded twice for quad thickness, it works really well and can be moulded around plastic connectors to protect them
Cheers Lee another good video , always put a video on mate as you come across very entertaining in anything you do 😂👍 better than watching the TV!
Ill take that! :)
Your videos are calming to watch and I have learned a few things. Glad you're doing a bit better Lee.
Hi Lee, just some info on the 6K board. Only 20k of these were produced before the 6U took over. So almost in the issue 1 ZX Spectrum gang.
Ah nice one Colin. Great info
Great to see you back on the main channel and in full form :)
Thanks mate! 😍
Even if you have sensitive fingers it's still a very hit and miss method beacause there are still many variables. The thermal camera is a good Idea even if even that isnt 100% either.
Yet another great video!! I agree about test carts. Sometimes, you just need to use an oscilloscope. Thanks for sharing
Love it! Moooooooh!
I love me a toast rack Speccy.
Oi.. Bad baaaad RAMmy! 😆
Beautiful video.
Thank you very much!
Nice fix Lee,, I'm still undecided which ddsoldering gun to get.
Totally depends on how much you're likely to use it. And even then there's a very good case for the cheaper one.
🐄🐄🐄How are you getting on with the new moo?🐄🐄🐄
It's getting better and better.
No noise is amazing. Quick to heat up, easy to use. I needed to remove 8 sockets from an Oric 1 yesterday, something I'd been putting off before, and it was an absolute breeze.
My only negative is the temperature control wheel. Just have to get into the habit of checking I've not left it on 450C.
Also would much prefer the lowest setting to be cooler than 350. For those extra delicate issue 2 Spectrums
You still needed to replace those other two RAM chips, though, right?
All three faulty chips were replaced
Hi. What thermal camera are you using?
Topdon. There is a video on my channel all about it
