Yes, is the short answer to this :). What has stopped me (mainly) so far is lack of source for the necessary slot in connector for the ROMs. If you or anyone else, has a source, it might be possible to make an upgrade to the programmer, it would require also some other stuff to make it happen...

FreeCAD, https://www.freecad.org/, is otherwise open source and powerful. It is fully offline. Personally I also use Fusion 360, but I'm not super keen on the cloud based nature of it. Fusion is a lot more forgiving compared to FreeCAD (in Fusion sketches does not need to have all constraints...

I might have a spare Nubus carrier for you, it is of the v1.2 but with a modified hdmi connector so the connector does not hit the back plane. Send me a DM and we can chat about. I have all of the carriers :) and can provide you a preflashed ready to use card if you want.

Haha, yeah, that IS a fair point, another “easy way” is to lift rhe VCC legs on the onboard ROM chips. I did that on the 475 when I did the first development.

I otherwise have ROMs here (Sweden) that work in the Quadra 650, can send it pre flashed.

@dougg3 has an excellent write up here: https://www.downtowndougbrown.com/2023/09/revisiting-programmable-mac-rom-simms-in-quadras/

If you have can find a case these work well: https://ko-fi.com/s/561c04e288

I dub this picture "The Tower Of Power":

It sure does :). I'd say that is probably the best base for a "generic" 68060 ROM for 475/575/605/650/800. Also absolutely amaing work! Very scientific and analytic, not like the usual "quick fix" myself tends to lean on :D. Do you know how much rom space the ISP and other things occupy? or...

Interesting, maybe this is also the reason why apple never officially supported 128MB on these machines? I have several spare High Resolution Video cards, can send one in next package.

Do you have any Nubus video cards? Would be worth seeing if you get display there and it does a full boot.

Pretty sure they had a LC PDS programmer with a DIMM socket and then flashed them using the Flasher tool on a Q605 machine. @dougg3 built an LC programmer (and later I made a proper board for it): https://www.downtowndougbrown.com/2023/12/more-fun-with-apples-internal-tools-creating-a-pds-card/...

Interesting that they used AM28F020 for those, it's also the same they used for the LOBOS board: https://68kmla.org/bb/index.php?threads/lobos-board-strange-apple-rom.39963/ And the STB3 (although in a different form factor)...

Me and @dougg3 discussed this topic like 2 years ago (time flies) :D, the idea was to make an adapter for the ROM SIMM Programmer that also could do the PPC ROMs, but at that time the biggest issue was us sourcing the necessary female slot connector (PPC ROM SIMM connector) for the adapter...
