Something just occurred to me. If you hook up the speaker leads to that card, do you get audio output from the machine through the line out? Maybe it's mixing the machine's built-in sound.

That looks like a clone of the MEK6802D5. It even has the same "0 F E D" lower row, though the G M R X column is a bit out of order. Seems like you should be able to power it up, the ground and power connections should be easy to identify from the data sheets.

I can't see the board assembly number, but that looks like a ROM 03 board, yes. It would be 607-0275-03. I don't recognize the Tapestry card (it just has a generic 87C51 on it, which is an 8051), but the speaker output might not be enabled if the rear headphone port is in use. Try disconnecting...

Just a 6802? No 6847 or anything else?

Not many were sold as they were exorbitantly priced, even for Apple hardware. If we want to turn this into a serial number tracker, I'm game. I'll get the ones from my production 500 and 700, since the ESBs and Deep Dishes don't really count here.

Speaking of oddball architectures, I've got a recalcitrant AT&T 3B2/310 I'm trying to get into Unix (it doesn't like the kernel). That's WE32000. The chips themselves have an interesting physical form factor. The Tutor keyboard is chiclet rubber and not nice for touch typing (the later Pyuuta...

I see you answered your own question later on, but these messages only ever appear briefly on the LCD. On the serial port they will be emitted as well (9600bps). The Gestalt ID is 67, same as the 9500/9600. I won't be able to access the console for a few days, but I'll dump when I get back...

Then unfortunately I'd agree the IDE controller seems like the most likely cause, or possibly the hard drive connector. There's just not much else to check. If you have a spare CardBus slot on it, you could try one of the CompactFlash adapters to see if it will boot from that.

Can you boot it from SCSI? That would at least help you narrow down the failure.

1.1.20.1. And yes, this is not my first rodeo, thanks. :P I don't even have the PRAM battery installed for all this and regularly reset the board between tests. That's my point exactly: it uses the PowerSurge script anyway, even on 1.1.20.1. That's why I don't think it's matching on that...

Not a lot on my first computer, the Tomy Tutor.

Just remove the 256K cache card. The ROM is not expecting it and it almost certainly won't work properly. That was never a supported configuration. You could try hard setting output-device to the Open Firmware path for the Rage 128. The path will vary based on where you installed it. Try...

I agree it shouldn't be used and it does not seem necessary. This is OS 9.1. There is nothing in the CDEV's table that matches AAPL,ShinerESB, so that wouldn't match the behaviour nor the Gestalt ID. Meanwhile, there is a difference in MACE Ethernet between the two ROMs: onboard works with 2.0...

Yes, I'll do the SCSI driver as well, though that should be easy using the same process as the video ndrv and it doesn't remove the external SCSI boot requirement, so I'm going to do that last. For me getting the Ethernet working is more important. The video extension is based on the 53m30...

Okay, I have internal video working for Mac OS on 1.1.20.1 with the 2.0 ndrv. I created an extension shell for it in ResEdit and grafted the code fragment into the data fork with a hex editor, and it worked on the first try. I'm now hacking the Startup Disk cdev to make the restarts better...

No, I don't think any of the 2.2 ROMs will work for MacOS, only 2.0 and 1.1.20.1. Love to be proven wrong, but I couldn't get it to boot on 2.2 and the others are not significantly different. Yes, 1.1.22 is the shipping ROM for booting AIX, which is what's in my production 500 (which boots AIX).

1.1.22 is the production ROM, which definitely won't work. 2.2b6 could be interesting, but doesn't have many differences from the 2.2NT ROM which does not seem to boot MacOS either, at least not in my testing.

It's not understood right now why it doesn't properly handle the cache. Repeatedly flashing the ROMs to test guesses isn't anyone's idea of a good time. I don't think this can be easily solved until we get the ANS emulated, which I know some Smart People(tm) are looking at, but doesn't yet...

I'll look at this when I'm back on that console (remote again). The drivers won't change the need for 1.1.20.1 to boot from the external SCSI port, though. My main mission is just to make Mac OS reboot reliably on 1.1.20.1, and that would be enough for me. The internal video isn't that great, so...

To distill it a little for folks who aren't sure, the main point is whether you need hardware support or performance. The 1.1.20.1 ROMs do not support internal video, internal SCSI and (it turns out) internal MACE Ethernet, and you may have to reset the board or monkey with Open Firmware between...
