Hello everyone! been forever since I have been on here. Hope you all have been well. ANYHOO, I recently came into posession of a Commodore 128, a Commodore 1902 monitor, and a Commodore 1571 floppy drive. The monitor and the actual computer are fine, and seem to run perfectly as far as I can test, but the floppy drive has something severely wrong with it. I am aware of how fragile the drives are, and have read quite a bit on the issue, but nothing is quite matching the experience I am having with my drive: It seems to initialize fine, and behaves fine until you actually send a command to it. Then, it will grind senselessly, followed by the flashing green light of error land. It can be turned off and re-initialized just fine, and any commands to force the hardware to do most head-moving tasks seem to go fine, but any actual read or write commands just fail with this same error. Here's the funny thing: thinking the controller might be bad, and noticing that the machine came with un-installed JiffyDOS, I decided to do my first IC replacement and remove the original controller, and install the new JiffyDOS chip. Installation went perfectly fine, because after install the 1571 does the EXACT SAME THING AS BEFORE! I actually laughed about it, since i clearly had done the install right, but it in no way was related to the drive problems. To give an example of the issue at hand, if you hit F3 for a DIRECTORY command, the drive will begin to seek, then, will begin it's flashing green light and the commodore will return to it's "Ready" prompt without displaying any data. I will record video of this later, as I just woke up and decided to post here (go figure, right?). I hope there is an easy fix for this, but if the drive is fried, oh well. I just have a ton of old floppies from the original ower, including much actually user-generated data that would be interesting to look over. Thanks. Again, I'll record and share video of the issue later today.
