I'd look for an old FireWire enclosure. Since nothing supports those anymore, they can sometimes be had for cheap, and most of them are bootable. It will be much faster than USB 1.1.
Actually, my favourite NeXTSTEP system is my SAIC Galaxy 1100, which is a PA-RISC HP 9000/712 in a MIL-SPEC portable workstation shell. It is very fast and runs 3.3 beautifully.
Maybe your card *is* in backwards. The silkscreened names are upside down relative to mine, but looking at the same landmarks (the connectors next to it), the chips on the card should be facing towards the outside of the case. Can you post a picture of the reverse angle?
Yeah, something's wrong. It should not need motherboard changes. A stupid question: is it inserted correctly? The card is not keyed. See the picture of my card here: https://oldvcr.blogspot.com/2021/02/the-quest-for-wolfenstein-3d-music-on.html
My A4000T has a Zorro Ariadne card. It's not a particularly fast card, but it works.
There is an 68K Amiga build of NetSurf you might try. It's slow even on this 68060, but it works, and you can access a lot more sites with it.
Realistically, it makes a decent 68K Mac into a poor Power Mac. I didn't find the value proposition for them all that compelling even when they were cheaper. I have one for my Q800 which I almost never use because it won't work with A/UX, which is what that machine usually runs - and I have...
Is this the card with a SIMM or standalone? I have an 8MB GGLabs in my ROM 03 and it tops the system off, but there should be no problem with 4MB on any ROM version.
Agreed, not for these. 1280x1024 should be plenty. I use a crappy old ViewSonic 4:3 with mine.
For the later VPro systems, though, regular monitors will do (my Fuel's V12 DCD does 1080p no problem, and has a standard DVI port).
Do you mean this ( https://www.amazon.com/CablesOnline-SunMicro-Monitor-Switches-W3-606/dp/B0C2MBSLB1 )? I've seen that cable and it will turn the 13W3 into VGA, and it might be able to put some sort of sync on the right line, but I don't think a passive converter will be able to fully filter...
I'm not very familiar with the original Indigo, but I just restored an Indigo2 very similar to yours: https://oldvcr.blogspot.com/2025/09/refurb-weekend-silicon-graphics-indigo.html
The Indigo2 is pretty tough. The power supplies do die, but recapping them needs to be done on the high-voltage...
Funny you should mention - I MITMed a number of transactions between my TechStep and various machines here in the shop and have traces of the communication. However, a lot of it is just uploading code to the machine and seeing what the result is, which makes forming a "unified theory" slow...
That would do it. But it's interesting you made an AIX boot floppy that way. I'm interested to see what actually got on the floppy disk if you can image it before you restore it.
If it's always halting at "System initialization completed" it doesn't sound like it's executing any of the rc scripts. What does /etc/inittab look like? What rc files are in /etc? (rc.tcpip, rc.local, etc)
