#Multiple Floppies HELP!

I currently have an A2000HD with two internal floppies as well as an external A1010. Since I am the software librarian of our user group, I'd like to be able to mass duplicate our PD disks as quickly as possible. So, I went out and got another A1010 and proceded to plug it into the jack on the back of the DF2: A1010. INFO recognizes that there is a drive out there as DF3: but the drive refuses to do anything. I've tried switching drives and confirmed that it's NOT the drive itself–the same thing happens regardless of which physical drive is last in the chain. Does anyone have any insightful clues as to how I can effectively have four floppies work on the A2000HD?

Kevin, The drive interface on the middle drive has to be modified. The 12v line isn't carried thru…but adding a jumper, it should work fine as df3: Don

Thanks for the tip, Don. That would explain the total lack of any activity on DF3: now wouldn't it! I'll get my trusty soldering iron out and try to find the hack file that someone else told me is on the nets… Thanks again!

Kevin, No need to look…just follow the lead from pin #23 on the input and find a convienent place to run a wire from it to pin #23 on the output connector. Don

Kevin: I believe the A1010 drive doesn't pass the power connector thru to the next drive, as C= wanted to limit the A500 owners to only 1 external drive (due to power supply limitations). There is a modification out there (I think the diagrams are available here on CIS) if you're a hardware hacker type, although that would also void your warrantee, or perhaps you could return the drive, and get a third party equivelent that does pass the power connector thru. -Mike Schiller CIS: 76416,3065

Thanks for the info. Maybe I'll try the Master3A I use on the A500 at work and see if it passes the 12V before I hack up one of the A1010's. That totally explains the apparent morbidity of DF3: Thanks again!

Do you think there are actually digrams for the drive pass-through hereon CIS. This is something I need. Neil
