I have a brand new still shrink wrapped 1740 and software here on my desk.
It's not a 174xB, but rather a 1740A. I think the package was supposed to
have a manual, but it seems to be missing. Its BIOS chip is labeled
"450216-00 A", checksum is DC00. The microcode chip is labeled
"450113-00 E", checksum is B7D6. Both have a copyright date of 1992. I'll
look for the box of boards and see what other revisions I have. I don't
think the 'A' and 'B' boards use the same BIOS and microcode.

I may have some other models of Adaptec EISA SCSI boards in the same box,
I'll have to look. I tend to collect odd boards for PC stuff to test Linux
and BSD drivers.

You don't want it anymore?
