Looking for a good ISA graphic board, I saw a Diamond Stealth Pro at ebay. Asking the seller if it is the ISA or Vesa-Local-Bus version, he answered that the card is VLB but might also work in an (8-bit!) ISA-Slot.
This seemed unlikely to me, but nevertheless I found this on the web:
"VLB Connectors are usually inline with ISA connectors, so that adapter
cards may use both. However, the VLB is seperate, and does not need to
connect to the ISA portion of the bus."
Does this also work the other way around?
Plugging a VLB graphic board into an ISA slot, maybe only with reduced speed? Does it depend on the graphics card type (some cards have the complete ISA-connectors whereas others only wear the 8-bit part : http://thegreenhouse.us/th99/v/vVESA_1.php) ?
Can I destroy the board plugging in the card (or the card itself - same problem like the 3.3V vs. 1.5V problem with early AGP-2x/4x cards/boards)?
In addition I found this old VLB card data sheet, which is also confusing ("What you need: one free 32-bit ISA/VESA Local Bus Slot; Specifications: ISA/VESA Local Bus slot interface..." ):

Edit: Tried it with a standard Cirrus Logic GD5422 based VLB graphic board, didn't work. Mobo's still alive... (used a SBC with ISA-backplane).
