Attached all the Open Firmware stuff from the ROM. You can use the tbxi command to dump other parts. Strange it has the same version as the 8500 v2 / S900 rom. 077d.28f2 "Boot TNT 0.1p..]" 4096 962f6c13 √ 676809c236138574282fa8416c6c5a6d "./ROM PowerPC Mac/ROM 1.1.22 ANS 500 &...

There's probably a way but I only have apps for Mac OS 9 and OS X - neither of which is usable by the ANS 700? The ROM is mapped to last 4 megabytes of physical memory. So, one would map it, then copy it. I don't think you can call Open Firmware from most OS's. If you can't find a driver or...

Does the ANS 700 have the same ROM as an ANS 500? Here's the version, size, checksum, and md5 of the ANS 500 ROM: 077d.28f2 4096 962f6c13 676809c236138574282fa8416c6c5a6d "./ROM 1.1.22 ANS 500 The ANS 500 ROM has an Open Firmware driver for the LCD which does support some control and escape...

I think pm7100 requires more work. Same for pm8100. You said pm7600. Did you mean pm7100? DBOF does have Open Firmware code for the floppy. I haven't tested it. Have you tried it on your Power Mac 7100? Is the floppy formatted with HFS or HFS+? I think only FAT (little endian bytes at 0x1fe are...

si is slow, especially when there are big loops. It might be better to add commands or code in DingusPPC to enter the DPPC debugger when the code at the PPC or 68K program counter matches some bytes (which you would grab from the Mac OS Loader file). Another option would be to alter the code to...

Made a fix for this bug in the last commit in my fork. Another note: when using si it may be useful to use context auto so that it will show 68K instructions instead of showing ppc instructions from the 68K emulator.

Control-D in a DingusPPC window will get you into the DingusPPC debugger. Control-F for full screen modes (integer scaling, full scaling, no bars scaling) Control-Shift-F for full screen reverse direction. Control- - and = for zoom out and zoom in. Control-S for smooth scaling toggle. Control-G...

Since input and output default to serial port B (printer port), you should set serial port B to socket. Easiest way to do that is set both ports to socket like this: --serial_backend=socket --serial_backend=socket The first occurrence corresponds to port A (modem port) because that is first in...

The resource nkld_128 of Mac OS Loader seems to be 68K code that loads opfw from Mac OS Loader. Mac OS Loader has a data fork that contains a PEF (search for Joy!peff) at an offset that is not zero. You can extract the PEF and disassemble that. I don't know what the data before the PEF is for...

That ROM nv_oem_4mx_1088_agp_64k.zip is corrupted - all carriage return characters were incorrectly replaced by line feed characters and there's no way to reverse the corruption since not all line feed characters resulted from the corruption.

didn't boot - are you talking about booting Copland or getting into DBOF? Are you saying you can't get into DBOF with 8+32+32+32+32? Not sure how dump-vt could fail. word not found? Not sure how words can disappear depending on RAM layout unless something got corrupted? Output from dev / ls...

An external variable _page is used to keep track of where it stopped. What's the value? Can you read from the address manually? cr _page 8 u.r cr cr _page c@ . cr cr _page ['] c@ catch if ." error: " 8 u.r cr else . then If you give an example of a bad address, then I can make DingusPPC do...

Here's an implementation with a second level of catch: 0 value _rerr 0 value _page 0 value _err : test-ranges ( max min -- ) do i to _page ( ) i ['] l@ catch ?dup if to _err drop else 0 to _err drop then _err h# fffff and 900 = if i ['] l@ catch ?dup if to...

But translations should exist as a word in Copland DBOF 2.0: 0 > see translations buffer: translations ok Are you using Copland D11E4 or an earlier version? I haven't looked at earlier versions. 80d get-token drop is only going to work inside the nvramrc before probe-all At the OF prompt...

You should be able to correct dump-vt for the versions of OF that it doesn't work on. It works for me with DingusPPC pm6100 with Copland DBOF. What error are you seeing? virt:00000000 size:00040000 phys:00000000 mode:00000000 virt:00040000 size:00040000 phys:00040000 mode:00000028...

You have the Open Firmware code (assembly and Forth) from my dump. You can look at the code to see what's happening. I don't know when real-base and load-base are setup/used - is it before Open Firmware has started (in System 7), or in the Open Firmware init code (Part1.txt) or in Open Firmware...

Silicon Beach Software was acquired by Aldus Corporation in 1990. SuperPaint became Aldus SuperPaint which is the version I'm familiar with. Adobe took over Aldus in 1994. https://en.wikipedia.org/wiki/SuperPaint_(Macintosh)

Appears to be C strings followed by variable type and bit number or offset (01=boolean, with bit number, 02=number with offset to value, 03=string with offset to string) So `real-base` is at offset 0x10 in the nvrm resource. It seems to have a value of FFFFFFFF = -1 in the Mac OS Loader...

I searched my Copland disk image for occurrences of a snippet from the nvramrc and found 7 occurrences. I mounted the disk image and searched only the HFS partition which also has 7 occurrences which means all occurrences are in the HFS partition. I take the offsets and divide them by 512 to get...

I did mention that in #7 You can set output to ttyb:57600 to increase the baud rate. A small patch is required to enable 115200 or 230400 bps. I made the commit in my DingusPPC fork. It makes it easy to get into Open Firmware on a pm6100 and it allows editing/saving the nvram...
