Those are awesome, but eyewateringly expensive with the FPGA board. I've wondered for a bit how bad a dumb framebuffer dumping to HDMI with a bare metal Pi would be as a low-cost solution? Basically take RGBtoHDMI and modify to bang NuBus with a level shifter just enough to map framebuffer...

@dougg3 is used to being famous at this point 😛

More pictures and a ROM dump would be interesting!

I love the keycaps, what are they? Also desk mounted Extron is brilliant haha. I need to copy that idea...

I should grab a picture, but my 040 has a standard early Quadra-style heat sink (vertical fins, not a crown), with a Noctua NF-A4x10 FLX on top. Those 40x40 fans happen to align their holes such that you can basically screw right into the heat sink...they fit between two rows of fins and it...

Radius cards are generally reversed and xor'd with 0xFF on the EPROM. Undo that and you can make sense of them. This can be different on each card, in another thread folks have been discussing the Turbo 040's extra complicated scrambling to further prevent reverse engineering, for example. But...

That puts it before the 2.0 firmware for the Radius versions, and it seems to have fewer video modes at a glance, so a ROM swap is a definite upgrade.

Try a Pro X or Pro XK ROM, they should be hardware compatible across the 7", I think.

Their high end monitors have been surprisingly great for over 20 years, though they are rarer than the run of the mill stuff. I've still got a 2407WFP I bought in 2006. Other than being widescreen it's an incredible little retro monitor since it also takes composite and component too. And does...

Did you just cut the old PSU cable and wire it in?

Is that the S2134 or a smaller one? 1600x1200 (proper aspect ratio!) sounds really nice but it's soooo pricy. I've got a beat-up 5:4 LCD I found in the garbage I've been using for my retro systems and the 5:4 just makes me sad. Do you know if it does 15kHz? The specs don't look promising.

I don't think there was a non-Pro XP...they're confusingly labelled on the board. Is it a 7" board? IIRC all the non-Pros were 12". Realistically it doesn't hurt to try the Pro ROM. In most worst case scenarios it just doesn't do anything. Interesting there was a Lapis-badged version. I've...

FWIW that circuit board looks pretty cooked as well. Like it got properly hot for quite some time. I'd check for other heat damage, shorts, and make sure the fan is moving air properly, or you might have additional failures.

Interesting. I wonder if it took a checksum of the entire chip and without those zeros it wasn’t valid.

Yes, it varies. Some (non-SuperMac) cards hang on boot so they're fully incompatible. Some cards (like SuperMac) are just not fully configurable so they "work" but occasionally that can cause problems when you need to change the configuration :). Even then, SuperMac cards can't change display...

Oh curious...I'm surprised it boots at all with no PROM. Maybe it's detecting the chip type before flashing and doesn't recognize it? Or you actually flashed it manually and it refuses to even read it?

Ah good point. I think 3.0 adds support for PowerPC, just 1.7.2 is required for proper 7.5.2+ compatibility.

268/256 matches the Sonic LC and Etherlan cards. I'd be surprised if that driver doesn't work (it certainly wouldn't be to spec for that not to work, since, if I remember my read of Designing Cards correctly, drivers match this 4-tuple).

What's the DrSW and DrHW on the Network sResource? If I remember correctly they need to be 260/256 to match the generic DP8390 drivers. You could try programming another ROM with the DeclROM modified to match those. But who knows if it's mapped memory to the same regions...so it might work or...

In case anyone else stumbles here: ROM 3.0 should be good on 7.5.2+.
