will a vlb card work in an isa slot?
will an 8bit pc card work in a 16 isa bit slot?
i recall having one 8bit that didnt work in a 16 so there is presumably some conditionality?
> having one 8bit that didnt work in a 16
If it worked on an 8-bit slot on the same mainboard then your port was dirty or broken. Otherwise, 8-bit VGA cards tend to be rather old and thus can have BIOSes with speed bugs.

There's no point even if it does work

The 8 bit card that didnt work was some kind of 3d glasses card, I recall getting a message that it couldnt work in that slot or that kind of slot or some such. The motherboard was a PA2013 board ie socket 7, so quite a bit newer. I no longer have the card [threw it away after that, and the glasses had leaked anyway].
Regarding VLB/ISA, I was thinking of whether a VLB board would work in a board that only has ISA slots, rather than using a VLB board in an ISA slot when you have a VLB available.
The pins of all ISA slots, no matter if an 8-bit slot or the 8-bit portion of a 16-bit slot, are connected to the same signals. There is no way for software to know.
There may have been ressource conflicts with your glasses card.
The VLB thing is still pointless imo. If it does work it will be dog slow, its end may bend somewhere where you wouldn't want to have it. In all the years I tinkered with computer stuff I never felt the need to try this out.

Unless a VLB card is designed to work with a 16-bit ISA slot, it will not work. If you would like to experiment, you can try out those VLB-based I/O controllers (IDE/Floppy/Serial/Parallel combo) on a ISA slot.
ok thanks, in view of what you both say i will not bother with this train of thought any further. twas prompted by some ebay items and the urge to build something i dont need anyway 🤣
