I haven't heard of those precisionbooks! Portable HP-UX. Pretty cool!
My conversations with Paul W over there at the beginning of the year led
to the creation of that page. He did all the hard work, I provided a
minor correction here or there.

Thanks for this.
I have another project I'm working on that is semi-related. The
NCR53C710 megacell as implemented in LASI is limited to 5MB/s. This
logic analyzer has no (physical) PCI slots, but has TE/AMP connectors
that are electrically PCI. I'm attempting to make a small adapter that
will convert that AMP to a standard 32-bit white PCI slot. The first
thing I'd like to do is try a 53C875E card.....to increase disk speeds.
There's a card that sits on that same bus which is wired directly to a
chip's PCI interface.....so I'm pretty sure this is the case.
I'm also pretty sure it's DINO that's bridging the processor/GSC bus to
PCI and exposing it on these connectors.
I've created a breakout board that takes the TE/AMP connector and
provides 20-pin connectors for a termination adapter to attach, which
then goes to a(nother) logic analyzer.

Right. I wonder if it's simply the matter of drivers. Do you know if
this scan is actually "ioscan -C disk" ?
Here's the ioscan from the actual hardware

Well it likely is. What I'm trying to do, however, have a sandbox that
very closely matches the LA that I can play around with, reset, break,
try again, and so on. There's other ways of accomplishing this, but most
involve physical hardware, re-burning SD cards, time, presence, and so on.
For my purposes, I don't know how much the LA's HP-UX installation
matches a standard one. And having the LA software might be nice as well.
For what it's worth, and I'm guessing you guys also have the bug ---
there's just something about taking a 25-year old CD, popping it in
software on a modern computer, and duplicating the experience. The mix
of old and new just does it for me! Hard to explain, but it's just so cool!
Thanks
Keith
