<The 3.5 inch drive conversion. Using modern media on this machine would <simplify things enormously. However I don't have the facilities to burn <my own roms, so if it involves patching the bios rom (like it sounds like) <I'll stick with 5.25 I guess. Just get a Advent turborom... TCJ has them. Since the DQDD 5.25 format is 781k and that works well on 3.5" disks as well. <That's right. It has the pads and traces for probably a 50 pin header jus <behind the floppy connection header. Is this where I'd plug in the <hard disk controller if I had it? And I don't suppose anyone ever made It use a host interface controller try TCJ or find a 1002HDO + MFM drive. <a SCSI host adapter for this thing? being able to use SCSI disks in it <like I do in nearly every other machine I own would be VERY handy. (yes, <I'm a SCSI bigot. I lothe IDE). No hope for SCSI though there was IDE interface. Allison
