[rescue] EIO card in HP 4M

[Peter Stokes]

Hi

Yes, silly price. I used them when they were current for a project. From
memory there was a U160 (7730) one and U320 (7732). I also seem to remember
there were SCSI issues with the U160 one and the U320 one worked better in the
application I had, but do not ask me to remember any detailsb&b&!

When current I also seem to remember they were around the $100 each mark, so
never cheap, but they did work reliably and pretty much the only game in
town.
