Hi Kenzo,
Post by KenzoThe 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.
I'm not sure that you can use a 1541-II power supply with a 1571. I'd do some
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.
Post by KenzoAnd 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.
Post by KenzoThe 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.
I can't comment on the 1764. I never had one of those.
Post by KenzoSo 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.
Most 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:
1) if you want to do it on the C64/C128, then use method 4 of:

2) get a Star Commander cable and connect the drive to a PC running DOS. Then
you can use the Star Commander:

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
