Nope, the BT-445S/C are really the only VL Bus options.  The VL bus
Adaptecs are AIC-7700 based (read proprietary downloaded microcode).

I've got a 24M system with a spare 1542 laying around.  The primary 
controllers are PCI (NCR and BT-946C).  The changes would have to be
1.0 compatabile.  After 11 months of tracking current, I've got a nice
happy stable system, so I'll follow source out of interest, but the
system stays put for now.  In a couple of months I should have a 2nd 
system that I can track current with again.
