560x384 is meant for Apple II graphics which has non-square pixels. Apple II graphics is 192 lines (half of 384). Double Hi-Res or 80 column mode is 560 wide (4 per NTSC color burst period). Hi-Res or 40 column mode is 280 (2 per NTSC color burst period). The 12 inch RGB display is a fixed...

Right. To boot 1.1.20.1 from internal SCSI, you would need Open Firmware to load the Mac OS driver from disk or add the driver to a PCI card with a flash ROM - any card should work as long as the flash ROM is large enough. You can make a ROM that has nothing to do with the PCI controller you...

Can you do a l2cr@ on the 1.1.20.1 ROM and do l2cr! on the 2.0 ROM? It looks like 1.x doesn't have l2cr@ or l2cr! words so you would have to define them. Only the 2.0 ROM looks at L2CR. The other 4 ROMs do not. So it's kind of strange that 2.0 has worse performance. Maybe it's changed by system...

The Mac OS X SDKs have StubLibraries including CarbonLibStub. That should be sufficient for linking? MacOSX10.1.5.sdk MacOSX10.2.8.sdk MacOSX10.3.0.sdk MacOSX10.3.9.sdk MacOSX10.4u.sdk Metrowerks CodeWarrior Pro 6,7,8,10 have a StubLibraries folder. These are part of Universal Interfaces -...

Remind's me of @JDW 's post at https://tinkerdifferent.com/threads/cracked-hinge-on-mac-portable.4835/post-42536 which I don't think got answered satisfactorily then.

Did you try the external SCSI of the ANS?

These are the ROMs: 077d.20f2.3 "Boot PDM 601 1.0" 9feb69b3 04200897.04838d09.037744f6.0418b271 02dcbf0e.03396836.0265e5ff.02bda730.02b66423.03964e19.02883f03.02e38f21:dedc602cfc3b9221 b40998471e33d802b350f699127e36df "1994-03 - 9FEB69B3 - Power Mac 6100 & 7100 & 8100.ROM" 077d.22f1.3...

A new thread describing conversion of a 7100 ROM DIMM to ANS 2.0 ROM DIMM with more pictures: https://68kmla.org/bb/threads/my-attempt-at-an-ans-rom.52132/

I did not do any reordering. kansas_deinterleave processes 8 bytes at a time. 4 pairs of bytes. Each pair of bytes is swapped. The first pair is output to U1. The second pair is output to U2, the third pair is output to U3, the fourth pair is output to U4. If this is not correct, then...

In that case, I wonder if it means anything that the Beige G3 doesn't have a U44? The schematic has 23 components with a U prefix numbered 1 to 47. Why does it skip some numbers?

Reconnaissance depends on the diagnostics mode in the ROM. The Mac has to work well enough to run that code. If the 3rd party ROM doesn't bypass the diagnostics, then it should work. But don't some of these ROMs skip the diagnostics (RAM tests, etc.) to boot faster?

Thanks for checking. That exactly matches the info for the 2.26NT ROM which we already have. 077d.28f2.1 962f6c13 045a4042.04a81401.033345a1.03ffe57d 02cdecec.031ec3af.0213d883.02837b28.02a7be75.03853500.023892c2.02a52e8a:c60da96de537f08a 23a7bbda5681be978972517d4758bbdd "1.1.20.1"...

Also this thread is interesting for really old Mac system software: https://68kmla.org/bb/threads/writing-an-application-that-runs-in-mac-os-system-1-using-codewarrior-gold-11.47511/

CodeWarrior Pro 6 was the last version of CodeWarrior to support 68K targets. CodeWarrior Pro 4 was the last to run on 68K hardware? CodeWarrior 11 is also an important version. Some other notes: https://68kmla.org/bb/threads/metrowerks-codewarrior-best-version-and-updates.42338/ I don't think...
