Apple Network Server MacOS based ROMs found

[mizerable]

When you are able to boot into Open Firmware, you can use the script at
https://tinkerdifferent.com/threads/apple-network-server-macos-based-roms-found.4756/post-41390
to see all the checksums.

any help on how to do this would be super sick, I didn't even know OF was capable of connecting via serial like this haha!

I have these two cables, one I bought specifically for using bbs and ATDpro on my iigs, the other I'm not really sure where I got it, old apple one with just an apple logo on one side, have two different usb to serial cables, tried for hours last night to get it to work with no success....any help is super appreciated!

The ADTpro cable should work. What did you set your Open Firmware variables to? Remember that port 2 is ttya, not port 1.

Try the "Connecting to Open Firmware" section here:

Connect to modem port.
In Open Firmware use this command to redirect input/output to modem port at 57600 bps:

" ttya:57600" io

To make the change permanent, you can use these commands to set NVRAM. The settings will take effect after restart:

setenv input-device ttya:57600
setenv output-device ttya:57600

Use a terminal app with XModem or VT100 emulation.
Increase the scroll back buffer to maximum so you can capture results of commands that output many lines of text.
Set the text pacing delay so that you can paste lines of text without Open Firmware missing any characters.
Text pasted into the dl command doesn't require a text pacing delay. Text pasted to the normal Open Firmware prompt does require a text pacing delay for strings longer than 14 characters or so.

Thanks for checking. That exactly matches the info for the 2.26NT ROM which we already have.

ah gotcha. welp, glad I could be of some information.

is there anything else y'all would need?

 

[ClassicHasClass]

Fascinating. A second 2.26NT ROM in the wild, though the one I have from @dbinreno has production labeling.

It is pretty cool, although ide be lying if I said I'm not incredibly bummed it isn't Mac OS capable, or at least something different than what y'all have seen already.

Looking forward to seeing what comes from this, I'll be around if anyone needs any help or info from me. o7

(Im fighting demons tryna not desolder the ROM chips haha...)

As long as it's running fully from RAM at the point that you switch ROMs it would work fine.

By this logic, do you think it would be possible to boot a Mac and physically swap the roms?

Let's say something like a 9500, boot, rip the ROM out, put a different one in and flash?

Or even, in the case of the TAM that has a built in rom, can you not just put a rom in after? I wanna test this when I get home if it hasn't been already. (Although I doubt it's the same pinouts on the tam)

We DID find a macOS rom from John. We are all trying to work together to find a way to get it to work for others who don't have the rom. I could be a programable flashed rom chip or @joevt is working on a boot loader type of idea. The experts working on this will see a breakthrough. Right now the flash is not looking the greatest but @trag is looking at it. I have my fingers crossed.
