Good and bad news... the replacement #PSU works, and the repaired PCB seems to work, too.
But the bottom read head is now confirmed dead. I measured the coils directly at the head. Like before, only the erase coil is intact.

Here a comparison of the old #powersupply and the replacement.
I already cleaned the old board, removed two rusted diodes, and unsoldered the ICs, but there might be more defective components, that's why I decided to replace it with something completely different.
Still unsure if I'll leave the cable binders for keeping it in place.

After getting the #Commodore #C64 and #C128 running again, the next device to repair is the #C1571.
It had #corrosion and #rust on the main board and the power supply is beyond repairworthiness. I'd replace the latter with a #meanwell RD-35 with 5 and 12 volt output.
One #diode was rusty, a few traces needed #cleaning and five #resistor looked bad. Hope the black hybrid chip is still okay.
Sadly, the lower read head seems to be broken, my work might've been in vain.

More cleaning done today. This time the #C1541 and #C1571 floppy drives, as well as the #C1531 cassette drives. They have quite some #rust inside, hope to get at least one running.
If anybody has tips for getting rid of the rust, feel free to tell.

So, time for some light #retrocomputing with a #C1571 for a #C128.

Just cleaning up some obvious yuck. Wondering if I dare connect it (are the PSUs here as evil as the #C64 ones?) to mains at some point.

Jak wgrywać gry i programy na Commodore 64 z pomocą emulatora SD2IEC.

Kilka słów o SD2IEC, następcy MMC2IEC, pamięci podłączanej do interfejsu IEC – uproszczonemu (niepełnemu) emulataorow stacji dyskietek do Commodore 64 i innych komputerów tej firmy.

Przydatne komendy SD2IEC:

Listowanie katalogów:
LOAD”$”,8
LIST

Przechodzenie do katalogu – ścieżka względna:
OPEN15,8,15,”CD/KATALOG/”:CLOSE15

Przechodzenie do katalogu – ścieżka bezwzględna:
OPEN15,8,15,”CD//KATALOG/KATALOG2/”:CLOSE15

Przechodzenie do katalogu wyżej/z dyskietki
OPEN15,8,15,”CD:←”:CLOSE15

Montowanie dyskietki:
OPEN15,8,15,”CD:NAZWA.D64″:CLOSE15

W komendach tych występują:
/ – ścieżka względna:
// – początek ścieżki bezwgędnej
: – oddziela ścieżkę od pliku

Dlatego np. można załadować bezwzględnie dysk:
OPEN15,8,15,”CD//KATALOG/KATALOG2/:NAZWA.D64″:CLOSE15
