How do a test if Parallel is working?

[Raymond Day]

I got my 1541-II working and I have a 15 pin parallel cable on it.

I guess it's my not be wired right to how the ZoomFloppy is.

I guess this is how I run a test for if the parallel is working:

"C:\Users\Raymond\Downloads\commodore ZoomFloopy\nibtools-msvc-opencbm5-win32-r58

7>nibread -D10 -t test

nibread - Commodore 1541/1571 disk image nibbler

If not what is the command to test if the parallel is working with the ZoomFloppy?

I think that is the right command but I can get the test to work. I think I need to make another cable. I open my 1541-II with the 9 pin Parallel cable I put down on paper how I wired it up to the 9 pin.

I need to go out and buy a 9 pin female plug and wire it up right with ZoomFloppy. So it will be 9 pin to 15 pin.

Hello Raymond,

Just to get it right: Your drive has a "track 0 detector" in it, which
is also connected to the parallel port?

Can the parallel routines cope with this? I would expect the track 0
detector to interfere with the parallel transfer in a fatal way.

Unfortunately, I do not have a drive with "track 0 detector" in my
cabinet, so I cannot test it myself. Can anybody shed any light on this?


Regards,
Spiro.

I put the track 0 in it like commodore did on I think the 1541-C but you have to cut a jumper on the 1541-C. They only had the DOS code in that ROM too and I copied that small code to mine. It's hooked up the same way commodore did it. I think it was jumper 3 but I am going by old memory's.

Yes. I got it working!

It looks like this now.

I spent about 3 hours testing the wiring with a tester and this web page help me a lot. From what I could see all the wires are right. So I got the edge port on the Zoom Floppy plug in like it would be on the USER port of the Commodore 64/128.

Now I need to test out copying. It should be fast.

Happy got this working I been trying from when I 1ST plug in ZoomFloppy.

I hooked it back up with my other 5 drives and I can't get the parallel to work with the Zoom Floppy now.

Guess I have to test one by one unplugging the serial cables and keep testing till it can do parallel again.

Maybe the 5 volts is not good for 5 drives on the serial bus. Not sure.

Hello,

BTW: No need to answer directly (or Cc: to me), I am reading the list -
obviously.

Just to get it right: You have 5 devices on the serial port, but only
ONE OF THEM connected via parallel, right?
