I have an '040 NeXTstation I would be willing to send you for the project, if we can work out shipping. It needs a video/keyboard/mouse breakout box to be useful without the original Megapixel display, however, and I don't have one.

Very, very cool. Let me know if you really are interested in extending it to NeXT, I would gladly send you a NeXTstation for development purposes.

In trying to add an Ethernet card to my 575, I encountered a documented hardware bug in a small production range which the community should be aware of. Two known good LC PDS Ethernet cards exhibited the same behavior: they would power on with the machine after a hard reboot (link LED on with...

First off, I wanted to thank everybody involved in reintegrating AppleTalk into 4.0. What a relief! The decision to remove it from 3.x ranks as one of the sillier missteps I've run across in the free software arena. I'm curious if there's any motion towards an AppleTalk implementation for...

Excellent, thank you!

These are PCI Power Macs, they do not have NuBus slots (and a Radius Rocket would be comically underpowered compared even to the stock single CPU 604 and 604e cards these machines shipped with).

I believe any 604/604e dual processor CPU card should work. The PowerCenter and PowerCenter Pro are quite forgiving.

Per the ANS 500 developers' guide, ROM should be addressable in that range. I don't know if the full firmware-assisted AIX sysdump will include it, though. Should be possible to dump ROM from OF in any case: 0 > 100000 0 do ffc00000 i 4 * + dup 3f and 0= if dup cr 8 u.r ." :" then @ 8 u.r...

Here's a ROM from a stock ANS, btw.

Wouldn't the ROM be present in the system dump in 0xFF000000 to 0xFFFFFFFF?

Could the ROM map be extracted from a complete dump, as triggered by AIX sysdumpstart ? https://aix4admins.blogspot.com/2011/06/aix-generates-system-dump-when-severe.html

Here's a photo of my friend's ANS ROM. These are the only identifying marks. He would be up for dumping the ROM if someone can come up with the AIX command(s) to do so.

I'll ask.

I've reached out to a friend who has an ANS, and he'll get me the ROM part number. I've also checked the 1066-page Module Identification Guide (and the European supplement) and it suggests that the ROM SIMM for the ANS 500/700 was not offered as a separate line item. Instead, the ROM SIMM was...

I haven't found any standalone G3 or G4 cards in that range (other than the Sonnet cards that don't work in the late PT Pro) that are affordable on my hobby budget. I have a couple of 400 MHz ZIF G3s and a 500 MHz ZIF G4. So those would seem to make sense. If they worked. I do have other...
