UPDATED February 4th: big, huge thanks to everyone who’s continued to help with this, including Daniel Forsythe!

First up, thanks to those who’ve helped with this effort, including Howard from the Netherlands and several others who wished to remain anonymous! Thanks to their efforts we’ve gotten a dump of one version of the elusive Cuda Lite chip found in PowerMac 4400s and the “authorized” Mac OS clones, and verified a couple of models to have certain chips.

To simplify things a bit for some people who were having trouble understanding if they could help, I’m going to try and be more precise here about what models have things I’m still looking for.

We’ve got a Kanga dump, item #1 is no longer needed! Yay!
1) MOST WANTED: main system ROM dump from a “Kanga” PowerBook G3. If you are unclear about which submodel your PowerBook G3 is, Apple has a visual guide. “Kanga” G3s were only available with 250 MHz G3s and were only available for a few months before the wildly popular “WallStreet” PowerBook G3s were introduced, so they are unfortunately rare today. If you have a Kanga, CopyRoms.

2) MOST WANTED: PMU dumps from a backlit Mac Portable (the original “luggable”) and/or the PowerBook 100. (We’ve gotten one since I posted this from a non-backlit Portable, which is fantastic!) PMURom will do the dirty work for you, you just need a working example of one of those three machines. It is likely that there are at least 2 separate PMU versions represented across those three machines.

We now have dumps of all known Cuda versions except the rare original found only in Color Classics. See item 3a.
3) Cuda dumps from systems with undumped versions. These are found in desktop systems with 68030, 68040, 601, 603, 604, and G3 processors. For the 68030, only 3 systems have a Cuda: the Color Classic, Color Classic II, and LC520. For the 68040, the Quadra 610, 650, 700, 800, 900 and 950 and the Centris 610 and 650 do *not* have a Cuda. All other 68040-based desktop systems do. All 601, 603, and 604-based desktop machines have a Cuda, no exceptions. (This means any “Power Macintosh xxxx” where “xxxx” is a 4-digit number rather than G3/G4/G5). For the G3, the original “beige” G3, the All-in-One G3, and the original “Bondi blue” 233 MHz iMac have Cuda chips. All later G3s (including all faster/non-Bondi blue iMacs) do not. (Note: we now have a dump from a Bondi blue iMac thanks to MAMEdev’s own The Guru; we no longer need dumps from Bondi iMacs).

3a) MOST WANTED: The model 341S0417 original-version Cuda found in Color Classics. We currently have dumps of all other versions known to exist; if you have a working Color Classic with its original guts (CPU upgrades are OK; full motherboard swaps are not), I would love to hear from you.

For best results on these systems, open the case and locate the Cuda chip. It is a small chip that should be located near the ADB ports and PRAM battery, and may have a Motorola circle-M logo. If the part number is not “341S0060” or “341S0788”, we need it dumped! Run the EgretRom program to create a dump. Note that multiple Cuda versions were found in the same model system depending on manufacturing date; we have word that at least 3 different part numbers appears in one PowerMac model, for instance. So if you have multiple of one kind of system, please check all of them!

I do understand on the iMac, Color Classics, and a few other cases that getting to the Cuda chip is difficult; in that case just run EgretRom and send the results and we’ll sort it out. In all cases, please include which model Mac the dump is from.

4) NuBus cards from Macs that have them. This covers most 68030, 68040, and many 601-based desktop Macs. If you aren’t sure on a 601 system, open it up and check if the slots are NuBus (big white connectors with 3 rows of holes) or PCI (small white connectors with a single “slot” surrounded by contacts). This is a multi-step process: first you run SlotRom, and it’ll create a dump file for each card in your system. Send these in along with, at minimum, the name of each card. A digital photograph or color flatbed scanner scan of each of the cards would be extremely welcome, but is not strictly required. For the photographs/scans the object is to be able to read the numbers on the chips; if you can’t do that in one picture but could take multiple close-ups of the card, that would be fantastic.

In all cases, if you have a dump and other materials, please email them to messdrivers (at) gmail.com or private message “R. Belmont” on the forums at forums.bannister.org or mameworld.info to arrange for a transfer. If you have any questions, feel free to contact me the same way, and thanks again!
