I just installed my second internal 3.5" floppy in my 2000, and it's nice to have a full complement of drives: 2 floppy, 1 hard. Now if I could only afford a twin 20 MEG Bernuoulli Box (and a controller that would run it... I assume my 2090 won't). It's QUIET!!! My 1000 drives were very noisy (gronk!), so it was nice to have the quiet murmuring of the first internal drive on the 2000. But the new one is so quiet, I have to look at the light to be sure it's working. It's a Prodrive (actually NEC), and now that I have it I can see why it took over a month to get to the top of the backorder list. QUESTION: If I want to switch the drives DF0/DF1, what do I need to do? Switching the cable alone didn't work (no drive activity at all). So, I assume that I need to change the jumpers. However, the jumpers look different, and are in different places, on the two drives. Is there some general principle that I can apply here, or the jumper method quite specific to each of the two drives?

So why not simply switch their positions along with the cable? You assumption of jumpers needing to be changed is/was correct. But since your drives have the jumpers at a different place, its safe to bet they are from 2 different companies and that the jumper settings would be different. On the lighter side: Whats wrong with 0 on the right and 1 on the left? Its been that way ever since the 4040 drives.

Well, I assume you know how to setup your drive as df0:. Since you didn't get it from us this is "your problem". Currently, B2000s with two different styles of drives have been shipped. One very simple style just has device select jumpers. Place the jumper on D0 or unit 0 zero select or whatever it may be called for the drive to be df0: and on D1 or unit 1 for the drive to be df1: The second, more complex style, has numerous jumpers for setting just about all the features of the drive. This is a model of the Matsushita JU-363, but some versions, with the same model number, have the simplified jumper settings indicated above. To use such a drive as df1:, use the jumper settings indicated below: bottom view of drive Drive Connector ========================= * * *--* * * * * * I I I * * * * * * * *--* D D D M D I D D 0 1 2 U 3 U C R "*" indicates a pin "I" and "--" indicate junpers Lastly, attach your df0: drive to the last connector on the 34 pin floppy cable and df1: to the center connector. This should do the job for you. -- (((((((((()((((((((())(((((((()))((((((())))(((((()))))((((())))))(((())))))) __ Ed Gunther COMMODORE AMIGA TEST ENGINEERING / /\ "The LAST line of defense, if "THEY" let us!" < == /__\ UUCP ...{allegra,ihnp4,rutgers}!cbmvax!gunther \__ / \ PHONE 215-431-9356 (life or death only please!)

I just finished installing a pair of ProDrives in my 2000 so I can offer a comment if you want to do it by changing jumpers. If you want the ProDrive as DF0: you will have to change the jumper in the block to the left (looking at the drive upside down, front towards you), it needs to be moved one position back (I'd make a picture but the drive is all fastened in and my memory is not that exact). Also remember to have the data cable positioned with the stripe on the left (The original drive that was with my 2000 was the other way around). You'll have to ask someone who has a 2010 what the jumper setting for that to be DF1: though. Hope this is some help. ---------------------------------------------- | David Fisk - University of Lowell CS Major | | dfisk@hawk.ulowell.edu | ----------------------------------------------

I've always had to go through a brief hair-pulling session every time I've sat down at a 2000 with two drives in it. I sit down, and insert my disk into one of the drives. Then, a blank expression crosses my face as I wonder which drive is which. I'm supposed to know these machines inside and out, so I resist the urge to ask which drive is which. So I take a wild guess and try df1:. Invariably, I get it wrong.

On page 4, paragraph #2 of the 2010 installation guide it says: "The 2010 will be mounted on that plate to the left of the first floppy..." ^^^^ ^^ ^^^ ^^^^^ ^^^^^^ The point im trying to make is that CBM has said since the 4040 that drive "0" is on the right, and drive "1" is on the left. > > So, dearest Commodore, could you print up some stickers for users to >use? > So if someone wants to switch these drives, thats their business, but CBM should not have to provide stickers. The person who switched the drives can take a trip to the local electronics supply house (or a hamfest) and buy a pack of press-on numbers/letters for a few bucks. >Leo L.
