That must be a slightly later card than mine, as mine still has the Emulex branded FAS101...
Edit: Also really interesting to have a shot of the SE 1, as I'd not seen one before, even more interesting that the SE 1 and SE 2 appear to be effectively the same card...
I would need to double check with an older system version, but I'm pretty sure it doesn't use the a/rose extension.
Also, it is possible to boot via this card, which means it is running before the OS loads. I think that however it is using the 68000, it's doing it using it's own rom...
All...
More research, the SiliconExpress IV has a QLogic scsi chip. Turns out QLogic was a spin off of Emulex in 1992. There are QLogic FAS101 parts:

I'm pretty sure that is total nonsense from that site...
I also have one of these cards, and at a cursory glance, the pins connected to the scsi connectors correlate with the Emulex ESP scsi controllers.
Google AI (actually useful for once) found this old oracle driver description document...
Nice work!
I have an old thread on here somewhere, also a Q800, where the cd drive worked but had really distorted sound output. I didn't know about recapping these drives back then, so I was advised by members here to do so.
When I took it apart and saw the state of the board I was...
Does your drive also have the front panel (Volume/Headphone) board? I have caddy drives that have that board and others that don't, but there are caps on that board too and it's connected to the audio out circuitry of the drive...
I googled and found actual pictures of a Big Mac, and it's definitely not that. I should have checked that before I posted!
Also I think the Plus has a 16Mhz clock anyway.
It's the fact that it's soldered to the logic board and that the part numbers are in-series that leads me to think that...
Hold up!
The part number and the silkscreen style - is that a factory fitted upgrade??
Edit:
This hints at such a prototype...

I have recapped and cleaned the board. The connector is in good condition. There were only a couple of broken traces on this one, none near the nubus section, cap damage on the lower half of the board was extremely minimal.
I have an update too - it is only SCSI cards that are unhappy in this...
See my last reply - the card has rom 1.16. I've just been using it in 7.6 and the only issue I could see is that the options dialog of the Monitors control panel doesn't show any of the card options when using SuperVideo 3.1 control panel. However, older versions of the SuperVideo control panel...
As per title, nubus slot A (the one with the inline DAV slot) works superficially, but attempting to use functions of a card installed in that slot freezes the system in pretty short order.
Tested so far with three scsi cards (SEII, SEIV, Jackhammer) as those are what I have on hand. All...
IME, old machines and modern switches or routers are rarely functionally reliable together. I have an old thread on here somewhere about my router causing my G4 cube to lock up after a few minutes of ethernet activity.
Why your 3400 worked normally prior to the drive transplant I have no idea...
