I just ordered one on ebay. Got it in the mail connected it to my vic-20 and powered it on. I Put a floppy disk in and when i did the (load"*",8 ,1) command nothing happens....The drive does not show the light that it is reading the floppy....it just stays in the searching command with nothing accessing from the vic-1541 drive.....Is there anything i can do? maybe the drive number has been changed? please help..... Crying or Very sad

Is there anything on the disk? Are you able to read a directory? Is the disk formatted?

maybe the drive number has been changed?

Did you attempt to ascertain this by addressing a different device number?

hi there it sounds like it could be either the right 6522 or the 74ls06
on the vic 20

either that or you have a problem with the logic pcb in the 1541
also check your cable try another one if you have one

The vic-1541 drive does not even make a sound or the red light comes on. It just stays on the search mode and the drive does nothing. Now i have another vic-1541 drive and that one works fine....So its not the cable, or the vic-20..it must be the 1451 drive....Please help me narrow it down

As gklinger said, have you tried different device numbers?

I got a drive once that been internally modified to be device 11.

I second this with the addition that it is more likely that you have to replace the 7406 and/or the 74LS14 in the 1541. You find them top/left on the board, near the IEC-connectors.
