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.

SD2IEC works perfectly with a c128, but i think any other device will do. :)
Hi,So my physical 1541 prevents the C128 from completing boot up when the drive is powered on and serial cable connected. If I kill the power to the drive while the 128 boot up is hung, the 128 completes booting. Same if I disconnect the serial cable

I should have a look at SD2IEC.
Would had recommended VICE, which emulated the C128, C64, PET,
VIC-20... And accepts .d64 files among others.
So my physical 1541 prevents the C128 from completing boot up when the drive is powered on and serial cable connected. If I kill the power to the drive while the 128 boot up is hung, the 128 completes booting. Same if I disconnect
the serial cable while the 128 is hung on bootup. And the drive does not respond to load command, 128 reports drive not ready.
I opened the drive case, board is internally very clean, and no burnt or bloated caps. I am guessing one or more of the logic chips is bad. Looks like the MOS chips are from 1984. I am using an aftermarket serial cable, the cable
pins look correct when compared to online pics, and continuity pin to pin on each end is good. I guess these serial cables are supposed to be pin to pin straight wired.
If I get some ambition in the next few days, I will use my scope to check for activity on the logic chips. My understanding is that with the scope ground on
a chip ground and scope lead on address or data pins, I should see high speed voltage oscillation, indicating logic activity...
Hate to give up on all my floppies, even if I pick up an emulator...
Hi Kenzo,thanks paul,

1. Bad power supply of the external drive.
2. If you have a 128D, you may have a drive number conflict. The internal drive is #8. If the external drive doesn't have some other number assigned (usually #9), then you will most likely experience exactly such symptoms.
3. The drive cable has a reset line (see below). Usually, it's wired through,
but I have seen few few cables which have no connection there. Considering your described symptoms, it may make sense to try with a cable that does NOT connect the reset line. The downside is that pushing the reset button on the C128 or even powering it down and up again will not make the drive notice any
change. If you want to reset the drive too, you'd have to do that separately then.
Reset is on Pin 6:

The 1571 won't power up but using the same power supply the 1541 II works fine. And the second 1541 also works fine. So I have two drives working, but not the 1571 yet.
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 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 powered 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 the 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.
I suggest

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.

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.

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.

Can anyone recommend the preferred drive emulator for making use of .d64 files?

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.

Thanks, I ordered a zoomfloppy today.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.
