Well, I have the dBit FDADAP. Works great. I have used them before on a PC to access PDP-11 disks from PUTR and E11. The P112 claims to support 8" but I am finding it unlikely. If it (well, at least the OSes it runs) don't even know it only has 77 tracks I can't see how anyone has done 8" disks on it. And then I went on to try the GIDE. I can't get FDISK to create partitions of any kind. I get Command (h for help) : n Partition number (1-8) : 1 First cylinder (1-17455, default 1) : 1 Value out of range And that is what I get no matter what value I enter. Why am I getting this sneaking suspicion that none of this stuff actually works? bill
