No, I stand by what I said. Older drives have removeable (either electrically, by jumper links, or mechancially, as plug-in resistor packs) 150 Ohm , or thereabouts, termination resistors. I've never see a floppy drive witha 220/330 pack, but I can believe they exist. Later drives, designed for use on short cables (for example inside PC cabinets) have fixed-in-place (often soldered CMD resistors) pull-ups of around 1k. These are not strictly terminators (they are nowhere near the characteristic impedance of the ribbon cable), they are just pull-ups, but they seem to just about work. I was told that having to fit/remove the terminators confused most lusers.... ao the manufactuers went to this kludge. Mind you, when I added a couple of 3.5" drives externally to my XT, I did add a terminator at the end of the cable. Inspecting the drives I was using showed the soldered-in 1k Ohm resistors, so I used 220Ohm resistors in the terminator. The combined resistance of the 2 1k's and a 220Ohm in parallel was pretty close to 150 Ohms, since I had the drives and the terminator close together at one end of the cable, regarding it as a single lumped resistor was not too bad an aproximation. -tony
