Probably pre-clock era. (And remember, it's a SCSI host adapter, which
translates from Atari DMA (ACSI, Atari Computer System Interface) to
SCSI, (Small Computer System Interface) not a disk controller... (love
those nested parens...))

I had an old one, which I accidentally burned out, sent back to Supra
for a replacement, and got one of the new ones with the clock in it.
(For a small fee, of course.) I liked the old one better, it would let
me use the floppy drive with the hard drive powered off.
