I have a feeling that it has to do with the NLX interface because I've tried plugging in different drives, removing them, swapping out the RAM, etc. I'm getting some floppy discs tomorrow so I'm guessing that I can just put a DOS program on there and execute the CMOS file (As I have the same issue with getting into the BIOS). I so happened to just have one, and I got something only once, but then it never booted to the Floppy again, which I thought was weird. One other interesting artifact that I found was that the PowerPC doesn't ever get past a certain point. I have attached the output below: snip But It never gets passed the Backplane anchor, Any ideas? This program is in the Flash on the Motherboard. The HDD seems like it's broken because it rattles, but when I plug it into a converter I am able to get all of the files off of it (so I made a backup). So I am kind of stuck here. I mean the other possibility is that this is just a motherboard issue, so I have a motherboard on its way to see how that turns out. Anyways if you have any input or thoughts on the problem(s), I'm all ears. Thanks, Simon --- End quote --- It won't get past that until the Windows O/S starts to boot. |

Cool, I got the unit to boot. I was using DOS 6.22, and a USB Floppy converter using Windows 10. I should have known not to do that even though I was running '95 on a VM. I just grabbed an old computer and boom it worked just as you said. I'm going to try to upgrade this one to XP as well. If I make any progress I'll post. Thanks, Simon |

They are available on eBay at decent prices. Then you would need the XP System Restoration DVD and an XP Pro licence to activate it. The application software can then be downloaded from Tektronix.

I ordered one of those boards (Intel SU810 NLX) because I have the MUCH older BL440ZX motherboard. I actually am pretty close to getting XP to upgrade on this setup (So I think). I have like 20 copies of XP Professional (all service packs). I've had a bit of success with SP2 interestingly enough. I made a copy of the other HDD to play with. Interestingly enough this scope didn't fail any of the tests. Maybe I got lucky? But it only loaded the software correctly once. I started sampling with the 80C02 characterizing a few pulses to make sure that the scope wasn't "lying" with its time domain and that all of the pulses "lined up" properly [I read your web page and looked for similar problems]. Too bad I didn't take any pictures because like I said, it won't go back. I think that the original HDD was corrupt so that explains all of the crashes. I've done quite a bit to the setup to make it run more smoothly, but it's still getting there. It might be a bad idea to try to get this current setup to run XP, but I've got until tomorrow or Wednesday until I get the motherboard so I'll just mess with it. Oh, I forgot to mention, I managed to get a copy of the system restore stuff too for XP. On another note: Have you heard of Win 7 running on these scopes because I found it interesting somebody was selling software for the scope to run Win 7? Simon |

Simon --- End quote --- Doubt that's possible. The i810 chipset only supports 512MB DRAM. The video chipset would be a problem as well. Where did you see that? |
