Unfortunately I don't remember. This was back in the late 80's, so getting on for 40 years back, and while I do have the source code, it's on 5¼" floppy. I just checked eBay, but the only USB floppy drives seem to be in the new-fangled 3½" size. I do remember that the clock that I made was on an ISA card, and presumably so were the DACs. I don't remember any difficulty in reading from them. It may be significant that I was only reading.
I think I'm going to see if I can find a service which will read the disk - it would be nice to have the code, though I remember there was a lot of stuff ♯defined out where I would have used SCCS once I had it available - hence it was a bit messy.
One little vexation was that although I had a vast 64MB hard disk, and a 1GB (bites tip of little finger) optical WORM drive, I had to reboot in to MS/DOS to use the WORM drive (no OS/2 drivers) and because one of the operating systems couldn't handle more than 32MB disk size, I had to partition the hard disk.
