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. > In qemu the B160L emulation isn't complete yet. > The SCSI disc is emulated by a "virtual built-in" PCI SCSI card, while > the original B160L has a NCR 53C710 SCSI chip internal in the LASI controller. > Additionally the LASI emulation isn't complete either. 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. > My assumption is, that your Install CD for the analyzer will only detect > real LASI/53C710 chips and ignore the virtual PCI card.

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
