Gouldfish on Games donated a parts machine ZX Spectrum Plus, but can I get it working? Or does it even need fixing at all?

Please make sure to advertise the charity when it happens, would love to bid!

[@MoreFunMakingIt]

Lots of news coming up on this soon! It's turned into a whole big thing 🤣

[@Zhixalom]

"... because otherwise people won't have anything to comment about." 🤣- that made my day ❤ - Always a good idea to feed the monsters, just to keep them happy. 👍 (mission accomplished)

[@MoreFunMakingIt]

I think it scares most of them off if Im too self aware 😆

[@RudysRetroIntel]

Super fast repairs! Excellent! More speccys back to work. Let us know when the charity is. Thanks for sharing.

[@MoreFunMakingIt]

Cheers Rudy! I will let you know. Hopefully not too long...

[@RetroBytesUK]

Its always sad when the ULA dies, there is just nothing you can do apart from find a replacement and they are becoming less common as time goes on.

[@MoreFunMakingIt]

Fingers crossed we'll start to see more of the modern replacement versions as chips become more available.

6:46 The Samsung made machines use different transistors - most of which are Japanese 2SC/2SA types. The pinout for these is always Emitter, Collector, Base (left to right). TR4 is a 2SC2236A in this case. As you note, the extra pads on the board allow the usual ZTX65x to be fitted

Nice to have a new vid 🙂 Keep up the great work 👍

Lee’s got a key…! ❤ you are also a GenX kid, so I guess you were a Lee-latch-key kid 😊 All name joke aside, a great video as usual!

[@MoreFunMakingIt]

Thanks! 😃

[@chaoticsystem2211]

One delete key attached to, uh, something

[@CurtisOvard]

Another speccy brought back to life, by plugging it 😂

[@MoreFunMakingIt]

🤣🤣 Gouldfish assures me it didn't work when he tried it. I can only assume I have healing hands!

[@CurtisOvard]

@@MoreFunMakingIt lolz the look on your face was great.

[@MoreFunMakingIt]

[@rossbennett5069]

Great vid. I’ll be bidding for sure.

[@MoreFunMakingIt]

Thank you Ross!

[@MoreFunMakingIt]

This has happened before. It just breaks sometimes. I'll check it again later

[@leesmithsworkshop]

@@MoreFunMakingIt I am happy with what ever charity you choose.

[@EgoShredder]

I'd like to repair my Sinclair ZX Spectrum 128K+ Toaster model, that I accidentally powered up with the polarity reversed one evening, due to being utterly exhausted and even had a polarity tester right night to the Spectrum. So going by online comments, I gather it will be RAM chips blown and I assume parts associated with the power supply input on the board. Does that sound right to you? If yes are those RAM chips easy to source?

[@MoreFunMakingIt]

I've not had the pleasure of a toastrack model to work on yet, but in my experience of the 48k variety when the wrong polarity is inserted it can be a whole range of possible faults. Could just be a few fried chips, or the CPU, or in one case I had just about every IC went faulty. Hopefully on the 128k version they incorporated a bit more protection than they did on the earlier boards. For one thing the voltage circuit must be very different as there's no need for a -5v rail. I wish you luck!

[@jaycee1980]

If you're lucky the 7805 and the voltage converter circuit will be bad, and nothing else.. but it can be a complete wreck

[@zxspectrum16KB]

Ula+ spectra?

[@MoreFunMakingIt]

Very expensive!
