Picked up this interesting card in a misc lot.

I assume quad serial?

It's a long shot, but does anyone have drivers? I can upload a copy of the ROM if anyone needs it.

Wow, another serial card! Maybe the card works without drivers, maybe you could try the QuadraLink or CSI Hurdler drivers.

It uses two of the same serial communications controllers that all Macs use so I guess each port can do AppleTalk? Maybe the ROM has drivers that are similar to the built-in serial port drivers? It doesn't look like it can do DMA?

Here is the QuadraLink v2.2 ROM dump.

Can you post Slot Manager info?
The SlotsDump app at #12 is one way to do that.
Maybe there's some other apps that can get the same info.

I wonder if SlotsDump can be changed to dump info from one of those .bin rom dumps. I'm not sure what the relationship is between what SlotsDump dumps and the contents of the .bin rom dumps (I haven't looked at the code in 20 years and I've never built a declaration ROM).

Here's a copy of the ROM.
Looks like 8KiB duplicated twice.

I was unable to unzip your SlotsDump file on my IIci using StuffItExpander 5.5 (circa 1999). If you upload a .sit or binhex version of the SlotsDump application, I'd be happy to run it.

What computer do you use to respond to posts in this forum? Any Mac running Mac OS X should be able to unzip it.

My modern computers are all PCs. Anything after MacOS 8.1 is dead to me. : )

Is sitx too new? I have Stuffit 7 and Compact Pro 1.5 (I don't remember the correct extension for Compact Pro archives).
There's a Slots app in the NuBus/Slot Manager folder of the August 1998 Tool Chest Edition of the Apple Developer CD series.

Found an eBay auction for a "working pull." I messaged the seller on the off chance they might still have the computer. Maybe copy the software. I really doubt it'll pan out, but who knows.

That would be awesome

Never heard back from the eBay seller.
