I wasn't complaining, Don. 8)
Just saying that I took your advice and it has worked out well for me.
As to the 9816, I was finally able, with Jon Johmston's (of hpmuseum.net) help to get TELEDIK.EXE to work on my old P75. I had to install and boot real MS-DOS before the low-level access to the floppy controller TELEDISK uses succeeded in reading the SS/DD disks I had. But I also proved I could write SS/DD images to one side of a DS/DD dik. That means I can use all the great 9816 software Jon has up on his site. So I'm sitting pretty in the 9816 department.
Loading real MS-DOS also made the NI drivers for my AT-TNT GPIB board work. It almost worked under DOSEMU, but that software doesn't do DMA, other than for the SB emulation. The "TNT" board is a high-speed GPIB card, and it needs DMA to make that work on the PC side. I'm sure I could get a slower HP-IB card to work under Linux/DOSEMU, but not this particular card. The Linux GPIB project drivers are supposed to work with this ISA card on a 2.4 or 2.6 kernel, but I haven't taken the trouble to build the custom kernel yet. I'm not hugely motivated because I'd also have to write a file system driver for Amigo and/or [CS]S80 to talk to any of the various HP-IB drives I have. As usual, data transfer, particularly software transfer is my main interest. There just aren't any extant drivers with source for these old drives, at least as far as I'm aware. I do know HP maintained drivers for use in HP-UX for many of these devices, but I'm sure they have long since stopped doing that.
