i noticed you use dolphindos as a base. Is there a disassembly somewhere or entriesn to its internal functions?

Ian of Dangerous Prototypes did it also. Flash Destroyer - DP (dangerousprototypes.com) and Flash Destroyer how-to - DP (dangerousprototypes.com)
I think the failere is sooner then he measured. To my understanding the floating gate gets wore down and it cannot hold it charge. I think after a lot of writes the bit will fade in a couple of weeks/days. that is much harder to detect and potentially worse in real life.
For the kungfu updating the firmware every now and then is ok, when developing the flash gets more wore down and can potentially be desasterious. Ie don;t use a developper mcu in a life saving device

Nice project. A bit overkill to use a processor with mouch more capabilities to run the show. The same goes for example a SD2IEC which has a mcu more capable then the C64 it serves
Are there any schematics avaialable? I only seem to find the gerbers.

is there a link to it?
No, sorry. It is currently still in the "beta" phase.
no worries I got an orignal

Eine "Expert Cartridge" fertig gebaut.
Nice one. Always had a soft spot for this cart.
is there a link to it?

solder without flux is like a**l s*x without lube..
I use this tip for all my soldering: https://www.amazon.com/T12-K-S…ork-Station/dp/B07JKSW931
How did the soldermask gets damaged like that?

Somebody wrote a magicdesk generator. It takes a couple of programs as input and generates a magicdesk cartridge file from it.

today picked up some PCBs and started with assembly: this is the first one (parallel floppy cable for C64 or S64):

Im currently waiting for my improved kff pcbs to arrive. After assembly i focus on again on the kff firmware
-
i got this problem too when i freeze the final cartridge on my sx64. I tweaked the timings but that didnt work :,(

xc95xl is still pretty much available.. even at the big distris

i think both carts have it appeal. The kff would be more versatile as it is easier to programm a micro for most people. The easyflash is a bit complicater to program. The easyflash can respond quicker to changing signals because it uses hardware gates for that. The kff is more time critical as things happen sequential.
The best solution would be a micro with a 5v cpld for fast switching.
For now im happe with my kff ,)

Gibt es eigentlich eine Seite wo man sehr viele Kernals findet?
Bei mir auf dem FTP für das Superkernal
The F64 Wolke also has a couple of kernals.
Bobbel can you please add me too?

Am besten, Du kommst nächste Tage vorbei ...
Solche Probleme habe ich noch nie gesehen.
ich habe den Fehler gefunden... puuh... VIA war ja o.k., C64 war auch o.k, also nocheinmal den WEG vom c64 zur Floppy ge-checkt !
-> die Userport-Platine "war" schuld... 
der Lötstopp-Lack ist etwas um die Lötstellen "verschoben",.. das "glänzende", ein ca. 5/100mm großer Punkt!!
=> siehe beim Pfeil !
der war es ! ich musste die Kontaktstiftte etwas mehr "belöten", weil diese nur schlecht das Lötzinn angenommen haben...
hier habe "ICH" eine Lötbrücke zu diesem Punkt fabriziert...
Diddl + Tommi_nrw hatten die ganze Zeit schon recht, dass das PA1-Signal Masse abbekommen hat.
(und da ground nicht "parallel verdrahtet ist", war der Fehler immer erst bei gestecktem Userportkarte entstanden)
puhhh.. danke für die Geduld,... nur läuft schonmal Prof.Dos !!
Most of the time the soldermask of the cheap chinese PCB aren't cured too well and not always good aligned. This is ok for prototyping.
It bit me several times

Your manual speaks about Superram-dos-DD and Superram-dos-FD. Is this a future project or something existing? A google didn't reveal much?
BTW nice manual
-
it will be used in a sx64 (thus original 1541) not an 1541 II.
No, it's actually not possible to use both and switch between.
Yeah found in the thread (at least i read upto page 37). Think it would be possible in theory when using 'switches' in some of the lines.
I think i need to get skme parta and my iron warm.

Yes, the mechanicle Drive works with 1541 Rebuild.
So you have the Sound
Ask Thorsten Kattanek for explizid instruction.
I'm afraid to damage the drive when using the 1541 rebuild. I still want to use the mechanics to read disks.
Thorsten Kattanek can you please enlighten me
-
Is it possible to use this together with a working drive? Like to switch between the real mechanics and the 1541-rebuild?
I'm assuming the mechanics still gets actuated and provide the real drive sounds
