I just bought and installed a used 16bit Perstor card on my BBS machine. It seems to work fine, though slightly slower than the 1:1 RLL controller I was using. I had a little trouble getting it installed, but a call to their tech support cleared everything up. From talking to others who have tried the Perstor card, I've found that it is picky about what kind of system it will run with. If you can get it working, it runs beautifully and reliably, but it is not compatible with all systems and drives. -- Jay Hofacker, sysop of the Audio/Visual Exchange, (606)254-1751 3/12/24 MNP 5 Mail: jayh@ms.uky.edu / uk02779@ukpr.uky.edu -- Yes, my signature is only 2 lin
