I filed that one in my Thunderbird email client's HP3000 folder and gave
it a red tag in case I need to find it.
Since I run a 957, I might need it.
P.S. I also found my spare for my Jamaica mirrored drive that became
disabled. I had those 4GB enclosures modified with 32GB drives. But
when you mirror them, the pair has to be the same make and model, not
just 32GB. So that ZuluSCSI looks appealing if you get it to work. If
so, I may have the fastest seek rate on the planet for my 957 Empire
machine. (99 bucks is so attractive.)
