I could not find anything like that on my board.

According to www.apple2.org all I need is an 8087-2 (8MHz part). I had a
search through my chip collection and found two 8087 chips (one with no
suffix is I guess 4MHz and one with -2) and two Sharp branded V30 processors
(40pin DIP)). I will have to try it out.

The HS SCSI card works as well. I have not got the s/w disk to go with it
(I had to partition a 200MB drive on the old Rev C card with the s/w that
came with it). It also worked fine with an unpartitioned ST251N drive from
my Apple //e.

Both the Rev C and HS SCSI cards can boot my Golden Orchard disk on my
1x Apple/Sony Caddy type CD-ROM. I bet my Pioneer 6 CD changer would not
show up as 6 CD drives - I rather doubt that Apple put LUN support in
either SCSI card.
