Hat vielleicht noch jemand eine MOS 8501 CPU für den #Commodore#C16 über? Die hier wurde vom Vorgänger bei einem Reparaturversuch falsch herum auf den Sockel gesteckt und ist dabei gestorben. Das Gerät soll weiter leben. #Retrocomputing
Ich habe gerade eine Einladung zu einem der nächsten Computerclub Treffen für Retro Freunde bekommen. Da lerne ich dann hoffentlich noch einige Gleichgesinnte mehr kennen.

💬Excerpt from an interview with Jane Jensen refuting the so-called experts of the time who claimed that the main drawback of adventure games is the inability to replay them once finished.
Interesting fault: After playing around with my childhood C64 breadbin from 1983, the screen suddenly lost all contrast and went very dark. #retrocomputing#commodore#c64 1/3
And there we go again! Larry 3 is on. Never played this one either! From the get go it already seems a bit more polished and seems to have more of a musical score, which is nice
I finally finished Sam‘s Journey and I must say it’s an extremely well done game. I „only“ got 63% score, so retrying a couple of the levels will definitely be on the menu! #commodore#c64#retrogaming#SamsJourney
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. #floppydrive#retrocomputer
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. #commodore#c1571#retrocomputer#restoration#meanwell#psu
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. #Commodore#C1571#floppydrive#repair#retrocomputer
At least my three #Commodore 1541-II drives are fine. They read my floppies and pass the tests. One of them even shows perfect #alignment scores.
I'll leave the 1571 alone for now, until I find a replacement or other solution.
Next, I still have a VC-1541 to repair. It had a bit of rust, too. Also, an #ALPS drive this time. #retrocomputer#1541ii#1541#VC1541
