There are chips that convert between serial and parallel ATA; one of
those could perhaps be used. I'm more used to applying them for
attaching a serial ATA controller to a parallel ATA drive, but
possibly they might work in the other direction as well. Not clear
if they are still common products, given that parallel ATA is pretty
old, but they may still be available.
Oh, I've got a pile of such converters--workability is variable.
What I was saying is that I've never seen an ISA interface card to a
SATA drive. Have you?

Well, I haven't seen an IDE interface card to a PATA drive either for quite a
while since they started integrating everything into the motherboard but OK, I'll
grant you that you'd probably need a PATA>SATA adapter if you wanted to Attach
a SATA drive to a genooine IBM AT.
And, that won't work, either. The BIOS in older machines
will not work right at ALL with a high capacity drive.
In some cases you will get a usable volume with vastly
reduced capacity, but in most cases it will just not
recognize the drive at all. I'm not talking about original
AT's here, but mid-90's 386 and 486 systems.
I can only imagine a real AT would be even less likely to
handle a drive over about 40 MB.
