'... and it's probably in Pascal'

Yes and no. For Slot Manager-aware ethernet cards, the system (technically the Network Software) provides a generic .ENET driver, which then looks for an enet resource with an ID that matches the Board ID in the card's declaration ROM, and hands the actual driver operation off to that. This...

Yeah, the thought had crossed my mind to just write my own special-purpose tool to install (and potentially uninstall) it. It's only Resources, after all. The Inside Macintosh-recommended way (for which they have example code) is to add your driver to the driver table at runtime (either in an...

Do you happen to have any pointers as to where I could find older versions? I might be missing something, but the only one I can track down is that (presumably rather late) version that I found on the Garden. That's the beauty of the 'write it all as resources' approach, I suppose! I've had...

I'd second the "explore the ROM" option. Even without having to disassemble the code, there's a mechanism for declaration ROMs to indicate the base addresses of devices to software (the MinorBaseOS and MajorBaseOS sResource entries). Not all cards use them, but if it contains those, that could...

As my ethernet card's driver starts looking more and more like an actual functioning piece of software, I've been giving some thought to how to distribute it - the SE/30 card's driver can be packaged neatly as a comd system extension that you can drop into your System Folder (only Network...

Interesting. I haven’t gotten that far through the video modes! I’ve been mostly looking at the init and driver code, and it definitely does some odd things in there - there are a few sResource IDs that don’t seem to be defined, and in at least one place, it seems to “manually” load an sBlock...

Ha, glad to help out! I think you should be able to use most sense adapters - the formula is, find the switch setting for Multiple Scan 16” (which gives the diode between SENSE2 and SENSE1, but with SENSE0 grounded), and then remove the switches that are common to 13” RGB (which grounds...

Yeah, I’ve been diving into that one with Ghidra lately and hooo boy it’s a bit convoluted. I’ll have to take a look at your code sometime. Ghidra is my weapon of choice for such things (I don’t think I actually have a modern enough Mac to run Hex Fiend on!) and it’d be really neat to try and...

Also, while I'm here, a bit of an update! I have a kinda-sorta working driver! It gets detected and loaded as it should, and the system doesn't crash at its mere existence, so that's very promising. Using the card with MacTCP, all seems to work as it should, it sends and receive packets and...

Oh that's right, they built that weird custom IIfx-based server thingy, didn't they? Makes sense, I suppose.

Never mind, took my other (now unused) video card out and it boots A/UX quite happily now. I think we can chalk that one up to A/UX just being picky about things.

My notes on monitor sense codes look like something you'd find in some cryptic video game puzzle

BINGO. After some trial and error, it appears that the mysterious E-Machines 0008773-0001 cable uses the Type-7 sense code 11-01-01 - SENSE0 open, and a diode from SENSE2 to SENSE1. With this sense code, and this sense code only, the Futura SX uses the rotary switch to select the display mode...

Here ya go. Nothing of interest on the back. The ROM board ID is “Futura SX”. When I got it, the rotary switch was set at 5 (832x624 75Hz). I’ve left it set there, but the only documented sense code that yields that resolution (16” RGB) doesn’t respond to the switch, so I’m assuming it’s...

No joy :( If I understand this FAQ page from Radius' old website correctly, the display-mode switch only functions when the 0008773-0001 cable is connected. The Presentor FAQ from the same website also mentions this cable, and implies that it supplies a unique E-Machines specific sense code...

Here are a couple that I have laying around, both from graphics cards (zipped because it won't let me upload them otherwise) memplus24nb.zip: Memory Plus 24NB futurasx.zip: E-Machines Futura SX

Just another data point; I put a Futura SX into my IIfx but I'm running into what looks to be the exact same problem - with a 10-switch adapter I can get any other screen mode out of it, but when I set it for 1024x768, it doesn't show up in the Monitors control panel, and the rotary switch on...

I'm certainly not aware of any cards for it! For 'pseudo-slot' cards that occupy NuBus slot space and don't do anything exotic, it's mostly compatible with the 030 PDS slot in the SE/30 and IIsi - the only major differences are that it's addressed as slot $E instead of $9-$B, clocked slightly...
