The 1571 won't power up but using the same power supply the 1541 II works fine.
On 8 May 2022 05:28:09 GMT, Paul Förster <paul.f...@gmail.com>right, i misspoke about 1571, it is the first version and uses just iec power cord. but it won't power up. I have book on trouble shooting and repairing C64, but since I now have three working 128s, fixing the C64 work will be on back burner, as will

Hi Kenzo,Zoomfloppy? Looks great for converting physical floppies to D64 copies in windows and reverse?

not the 1571 yet.
research before trying that because a bad power supply can not only not power
up the attached device correctly but it can kill it. So I'd be careful when trying a Commodore power supply with a different device than what it was built
for. You should basically always assume that Commodore power supplies are NOT
interchangeable between devices.
And I had 4 computers in storage, a 64 and three original type128s. The 64 powers up, but composite connected monitor is blank. I have to do some research for that. Maybe the 64 does not output composite video?The C64 has a composite signal. It's pin 4 of the connector.
See: http://www.hardwarebook.info/C128/C64C_Video
But your VIC chip may be fried (or the monitor of course). Or it may suffer from a bad connection. It's hard to say without detailed info. I suggest taking the VIC chip out and clean the contacts, then put it back in. This can
be easily done if the chip sits in a socket. If it's soldered in then you may
have some soldering to do. But instead of soldering it back in I would put in
a socket.
The three 128s all work fine. Next I will try the two 1764 ram expansion modules. The one I have that was boxed comes with a commodore higher poweredI can't comment on the 1764. I never had one of those.
power supply. I will check the output voltages before powering up with it.
So now that I can read disks, I guess the next step is to clean and lube theMost things are on the web already in d64 format. You'd have to search hard for some things, though. But if you want to do the conversion yourself, then there are several options, of which I can recomment two:
drives, and then figure out a way to convert the physical floppies to .d64 files, since I don't expect the drives to work forever.
1) if you want to do it on the C64/C128, then use method 4 of:
https://diginoodles.com/writing/media-production/transferring-commodore-64-disks-to-modern-formats
2) get a Star Commander cable and connect the drive to a PC running DOS. Then
you can use the Star Commander:
https://sta.c64.org/sc.html
Though the second option is very comfortable and reminiscent of the well known
Norton Commander, it requires an old PC running DOS and having a parallel port. You'd also need to aquire one of the X1541 flavor of cables. It's all documented on the Star Commander homepage.
Hope this helps.
Cheers
Paul
Can anyone recommend the preferred drive emulator for making use of .d64 files?
I want to run the .d64 files on my 128 after I have downloaded onto my windows PC.
I see various hardware on the Bay but not sure which will work on a 128 in either mode.

It is likely that the power supply has failed.
The 1571 has a very simple linear power supply. It should be easy to
fix.
There is even a fuse, winch needs checking.
Also, the solder joints for the transformer can crack. The transformer
is heavy, and there is nothing other than the solder joints holding
it.
Be careful with mains voltage, though.

I'm really liking this thread.
Just wanted to chime in that I too have a C64 that powers on with just a black screen. I tried changing out the VIC and that made no difference.
Even tested the original as well as relacement VICs in a known good
system, and they both work fine. The first suggestion I got was to try replacing the PLA, which I did, and also made no difference (also tested
that in the known good system). I don't _see_ any issues with any of the
caps on the board, but that doesn't necessarily mean there aren't any.
I'd be very interested to hear what's causing yours to do the same if
you should find out :).
Jelly of your C= collection! Never had a 128.
