@LaPorta Do you mean like restoring a backup from a current machine back to the Mac? This is not implemented, the Mac just sends the disk data out to another machine. But theoretically I guess it should be possible. Probably one needs to boot of a floppy, else the running System gets overwritten...

The checksum is stored at the first 4 bytes of the ROM. "DM 40800000" in the debugger would show it.

@cheesestraws ahh i see.. if youre in deep shit you need to do error handling... makes sense 😆.. i'll see if i can rephrase the syscall thing @tecneeq one could try to see if the keymap memory region is properly populated when pressing esc + l + f + w. This can be done by entering the debugger...

Hi Everyone, I got the write-up together, you can check it out on my new page: https://nerdprojects.ch/projects/iici-easteregg-hunt/ @tecneeq Did you get the easter egg going? Or do you have maybe also a PPC upgrade installed? I though another source of error could be the keycodes, that might...

nice!!! thank you all so much for verifying this so quickly! i'll finish my write-up and will add a link in this thread.

:D great!!! the draw routine seems to be fine... maybe the issue is, that there is a check upfont the check routine I missed... or we could also quickly check the bytes of the check routine, to see if it matches the one I looked at. could you dump it for me? DM 4084f154 mine looks like this...

I checked the code again and i still think the key codes that are checked are ESC + L + F + W... Have you maybe tried I insted of L... Or there is a check upfront I did not took into account. Another test you could try is to start the debugger (use the interrupt switch) and jump to the address...

Thanks for trying! I'll have a look again at the Quadra 650 ROM, to see if I missed something.

Hello Dear Forum I reverse engineered how the IIci easter egg image is stored in ROM and created a Python script that extracts the image from ROM files. I ran it over a bunch of Macintosh ROMs to see if there are other, yet unknown, easter egg images. Apart from the already known easter egg...

Sounds like a interesting project! Go for it bw:)

Once again... here is the file: 

reattached file... i think the migration of the forum mixed up something with the old attachment

Hi There   I want to share a backup application I made. It can be used to backup Macintosh volumes over the serial port. I created it, because I couldn't retrieve data I had on a exotic SCSI 40 pin harddisk used in the old PowerBook series (e.g. PowerBook 140, 145B, etc.) The only interface to...
