Really pisses me off that I can't find my ZX Dandanator Mini. You just made me more desperate to find the f-ing thing. Nice video, Rudy! See you Sunday.
Really nice round up, thanks for doing that, good to see them all sode by side like that. I would agree with your winner from a diagnostic perspective tho I really love my Dandanator mini as it can do diagnostics but its a really quick way to load games (tho writing the ROM can be a little bit of a faff). Also it has a really nice snapshot feature which allowed me to save scum my way through NOMAD which was too hard for me 😂
Thanks for commenting. I like the Dananator mini but a pain to copy games. It would be better to have an SD card so you can copy and paste games. All are good, it just depends on what you need.
I have got the kit to make. A very good way with the resistors, I will do the same, I got a cheap oscilloscope of Ebay a DSO-TC3 Oscilloscope. For me its ok I hope to use it not alot.
LEDs are not real-time. You cannot see the data and address bus activity of a computer running at 3.5 Mhz by eye, all the LEDs would seem solidly on all the time. The diagcard uses a simple trickery to slow the blinking of the LEDs to provide a visual representation of the data. So, I don't think clipping the oscillator probe to the resistors will show you real time info too.
By clipping and oscilloscope, you would get some useful information. Like seeing if the CPU is getting a reset signal. The other signals may be filtered. It would depend on the schematics of the diagnostic cartridge. To truly do a full repair, you would need to open the case and use the scope probes directly on the ICs. No diagnostic cartridge can truly replace an oscilloscope with direct access, but this this cartridge is still very useful

Thanks! Check ZX Rwnewed site, as that's where I got mine. Thanks for commenting, and see you Sunday!
@@RudysRetroIntel Oh, no. Not buying another one. I've got to find the one I lost. I'm sure I put it "somewhere safe", but that's how I lose things!
Nice video Rudy! This is very useful stuff. I'm definitely doing that resistor mod whet I get my one.
Thank you, and thanks for commenting
peek inside and poke around - I SEE WHAT YOU DID
You're the first! Congratulations! Thanks for watching and commenting

Great review Rudy
Thanks, and thanks for commenting
Wow, had no idea there were that many diag carts for those!
Me too! Could be even more, but these are the ones I found. Thanks for commenting

Glad you like it, and your oscilloscope should do just fine. Thanks for commenting
