… or how to reanimate a dead breadbin case
Photo of a week
I’ve been doing some cleaning some time ago and I’ve found a breadbin case. Unfortunately, it was sorta fatigued. At nearly the same time, I’ve finally managed to successfully repair a breadbin motherboard – 2504007 rev. B. But let me start from the beginning.
The plan was to repair an old case, supply it with the proper keyboard and insert a freshly fixed motherboard in it.
Breadbin case fixes
I’ve sanded a putty once it was cured.
I didn’t bother to fix minor imperfections since another layer of putty (spray) was planned.
Next step was to apply spray putty, wait until it’s dry and sand it again afterward – repeat if needed. That fixed all minor scratches and filled small holes.
Here is a shot after doing the first round of the above process.
In the mean time, bottom part dried and was ready for spraying with a layer of blue paint 😉
Another thing that had to be done was to 3D print a replacement connector plate model that I’ve found on Thingiverse –> Model here
Some failed 3D prints later … 😉
Motherboard that I’ve got was pretty much dead.
Quick diag tests followed and I already knew that
PLA chip and both CIA chips are fried.
At that time I was only aware that PLA chips often fail.
However, I didn’t know what is the exact cause. Quick google explained a lot.
Here is a relevant article
Anyway, my original PLA was fried and I didn’t have a replacement. Me and Johny/Lamers tested EpromPLA the other day but we’ve killed it in a process 😀
However, I still had a PCB for it. I’ve come up with an idea to put binary PLA dump on a flash chip – SST27C512.
FlashROM PLA might not work with every software/cartridge but it surely works with SD2IEC and loads most of the games and software just fine.
That’s it. New builds are coming 😉
