Interesting, didn't know Rev.C was the only one capable of supporting a Wifi card. The major difference I see between 1400/5x0 implementations would be the IR hardware. Assuming the T-REX ASIC to be identical, that ROM on the Blackbird modules looks like a system patch to me? Has anyone tried...

Glad to see someone jumped on this so I don't have to get involved. I have two full sets and a penchant for procrastination. The silly things are anything but ergonomic. They look great, but function is worse even than the PowerBook case equivalent. They're functionally useless, which is why I...

LOL! I've had my nose poking into just about anything interesting in hacks and peripherals over there. Those two forums were my turf as a mod back in the day. :) You may be right. Thinking about it, I don't see PCMCIA as much more than a novelty for the Blackbird at this point. SCSI/SD...

Aha, thank you! From Charadis' credit, it looks like I came up with the crazy notion the assemblies might be compatible in a previous lifetime. I said then that I didn't think an adaptation would be possible. But now I think it might be done, go figure. Connector limited project: I'll take a...

Thanks, should have figured out it was RAS from the way they run across the ICs as if P&G to the corners of the chips. Brain's only partially online lately, trying to shake off Wuhan Wooziness. Cool, at least some of my noggin's still up and running. ;)

@lilliputian it was just the title of your old thread that set me off this morning. Just read the thread and it seems the PCMCIA cage is rare enough to play with here?

Has anyone got really high resolution scans of the parts? Never seen 'em. I've been playing with a 1400 PCMCIA cage/daughtercard to Duo HDD bay transplant about as long as the MLA has been around. Just occurred to me that the TREX ASIC would either be on the Blackbird module or would be...

Forgot to ask about the two wires on the layout. Couldn't see if they lead to addressing for a single or multiple Ranks. At first glance I'd thought you were powering that bloody big bodge of ICs, very clever way to implement the jumper wiring. Will you be adding the matched header to your...

Fabulous, max!

Yep, what kind of switch setup remains the question. WAG would be simple rotary any one of three or the likes of a SCSI ID push button switch selection of same. I wonder if someone with logic analyzer might yank on one of the two "unsupported" interrupt lines to determine if the CPU takes...

I see you have only the jumper for Slot 4 enabled. That's likely for the accelerator . Are the other three selected for use of one card at a time? Does a cable plug only into the other three headers and if so, what kind of switch setup?

Great, when I feel up to it, I'll detail a couple of methods to go about doing a life mask of that beautiful thing.

IIRC, there are three interrupts on the LC PDS, but the PDS docs asy tha only one is supported, so that wouldn't be a lack of physical connectors. Read another way, you could be right, the three interrupts might be supportable in additional slots? I wonder if someone figured out how to map...

@KennyPowers are you in the US? Making a plaster cast, negative mold of that front bezel would be a fabulous project! I like that your dad had a removable drive cage set up in his server, that kind of thing was right up my alley back then. ;) Is the surface of the case smooth or textured?

Accelerators don't tie up the Slot E interrupt of the LC PDS or any other PDS in any other Mac. The Accelerator is the computer (CPU) that needs to be interrupted to service the expansion card as I understand it. In at least one of the expansion chassis implementations, the multiple cards are...

Interesting question. :unsure: I'm going to say it's not likely because one of the first things the IIsi does at startup is to poll the sense lines on the video connector. If a monitor is detected, a portion of Bank A is buffered for use as Vampire Video's VRAM. If none is detected, the system...

Shipping product is the art of the possible. Engineers did what was possible with available technology in the face of incredible wrongheadedness on the part of SJ and shipped what the Mac should have been at release but for Scully hamstringing memory just a few months later. Better to develop a...

Moved from other thread: Your small controller board would have to be the equivalent of a VidCard with driver to enable the CPU to load its frame buffer. At that point RAMDAC converts it to analog video signal on the mobo connector? I think this is wrong though, see below: PowerR is a baseline...

moved to other thread.

Looks like a great way to decorate a wall AND keep nasty electronics out of landfill burial sites. The parts themselves won't lose value on display in the case that collectors ever do want to buy them off your wall for restoration work. The frame looks eminently re-usable for other...
