....and no difference :( As I forgot to bring a 'scope home from work for the weekend, I'm a bit limited on checking if this has improved the signal levels on the clock or not. Using a DMM I'm seeing a resistance between 0v and the 32MHz Osc output (after the inline resistor) where it was showing 0/...

Maybe not so easy to miss with the tweezers though?

Ok, I remembered to bring the resistors home for the 32MHz OSC fix, so will try to fit one after work today...

I'm going to try this on my newer H5C1...but any chance of photos of your working board please @alienkidmj12 ?

Just in case it's not just the osc output....

Thanks!

That looks really good - where did you get your supplies from? Hoping to avoid any dodgy ones if possible...

And would it only need the 5V if it were to be used with an H4/H5 board?

I'll need to check when my son starts back at uni - should be able to find out by the weekend. I'm not fussed about which day at the weekend though (but I'd probably take my son over on a Sunday)...

Just my 2cents, I had no-end of issues with white screen on my H5, even though I had top-quality 3M sockets. In the end I got rid of the socketed chips and replaced them with the SMD variants (talking about the system chips) all my problems went away :) Interesting...I'll try to remove, check pins ...

I'll get a photo late tonight or tomorrow, depending on how late I get back home. It's a white screen on boot again so I'm wondering if there is a poor connection somewhere and soldering in the floppy power lead disturbed something. Not sure it's related to the floppy yet...needs a bit more diagnosi...

Well, I fitted the floppy power lead and the board is again booting to only show a white screen (keyboard LED is lit, getting about 5.09v on the +5v rail)... So looks like it will need even more diagnosing at the weekend or next week. :( I'm out tomorrow (leaving very early & back late) so littl...

Badwolf At some point I'll get at least one of my H5C1 boards working & then try to finish off the build of my DSTB1...then we might have more for comparison. I think it's fitting a few of the caps plus programming it up that is still to be done, but I've no idea on how long that will take (sev...
