Ten Year Rule

Only because that's about the loswst spec you'll find in a modern 'scope. I sucessfully aligned a 3.5" dirve using a very cheap handheld digital 'scope (IIRC 500k samples/second, it did an aliasing trick to look at _repetitive_ wwaveforms up to 5MHz). ANd just one trace). Did you actually try to align a floppy drive with it? Actually, if you want to align floppy drives (and nothing else), I would try to find a thing called a 'Microtest'. It's a box containing an ADC and a microcontorller that links to a PC serial port (_Any_ PC with a floppy controller and a serial port, I think you need 256k RAM and any display adapter, even MDA). You link up the drive under test as drive B on the PC, and run the software that comes with the microtest. Then select the drive from the menu (and there's every one that _I've_ ever wanted to work on), it drwas a picture of the drive PCB (using IBM line-drawing characters) and tells you where to conenct 5 clip-leads from the ADC box. Then put in a standard analogue alingment disk and it will tell you how far off-track you are, if the track 0 sensor is correctly positioned, and so on. Of course I need a 'scope for lots of other things, but this little toy really is fun... I assume that is very much tongue-in-cheek... -tony
