Nice, I usually remove the 7805, clean underneath and lightly sand down the surface of the aluminium heatsink to shiny metal, apply a tiny tab of thermal compound, and reinstall the 7805. I find that although not essential in a Toastrack, this significantly improves the cooling of the regulator.
For the voltage regulator i use RS part number 193-4015. You can then remove the heatsink completely (on the rubber key versions). It vastly reduces the temperature inside case and reduces the stress on every other component as a result. 👍
@@HappyLittleDiodes It certainly does - you're correct about that. But for me, I'd prefer to protect that ULA which boils along all by itself. It also protects the electrolytic caps (they're temperature rated) and the keyboard membrane. Of course, it depends how much they are going to actually be used in real life. Back when I was a kid my Speccy would easily be powered up for 12 hours at a time - maybe even more. These days, I'd be more likely to fire him up for half an hour to blast some Mainc Miner (the best game ever written!). Really enjoy your channel. Your channel and More Fun Making It are my faves! 👍
Nice. A couple of questions ... 1. Why does the EPROM need a sticker? 2. What's the danger of putting the board in a vice? Does flexing the board not cause issues? A final weird one ... what do you do with the legs you snip from the components? Do they have any use at all? I'm not a fan of waste.🙄
The EEPROMs with a window are designed to be wiped clear by UV light. So it they are left exposed they can lose data. I find as long as you are careful the board won't flex any more than normal. Obviously you have to be careful not to over tighten it though!
Where did you get the new sticker from? I need a replacement for my toastrack. I was thinking of removing one from a spare 48K+, but I would rather not do that!
Drugs and rock and roll! Outrageous. I believe we were all looking forward to you putting 9 million sockets in the nucleon ?
Yes! I'm going to get on that soon
Brilliant job mate,love the attention to detail as always!
Cheers bro!!

Good tips! Thanks
Joyously relaxing, I really enjoyed this video. I hope you have loads of fun with your Toastie!
Thanks very much! I definitely will

I'm on the fence about this because I like the weight and the warmth of 7805 and heatsink it feels authentic!

Great video! I just saw today that Zilog have just announced the withdrawal of the ubiquitous Z80 after 48 years in production! 😢
I know! How sad. I wonder if prices will go up quickly??
@@HappyLittleDiodes Probably. I was thinking about stocking up.

Sadly I haven't thought of a use yet for cut legs :(
15:32 you missed one ! :) top next to the video socket :)
Those GSS z80's always seem to die. Suspect on sight!
Seems I got it later! Don't remember it though. I will remember that about GSS chips
Any chance you could do a video showing “Desoldering by mind power alone.”? I know it would save me many painful hours and burnt fingers. 😂
I'll see what I can do! 🔮

Have a look on "sellmyretro"
Great Video, where did you get the replacement GAL chip from?
Thanks John! You can get them preprogrammed from retroleum. Otherwise, you can program them yourself I believe, the files are all available
Ha! I put the 128th like!
😂😂
An ultrasonic cleaner makes cleaning keys much easier.
i have 2 'toastracks' one with mask rom one with eprom, dunno if one is more common than the other!i
I'm not sure either but I've definitely a few of both
are you from bradford by any chance
Haha not tooooo far off. An hour or so North?
