Those original snakes have the ASP bus, which is quite similar to the LASI.
You can look at the Mach code for differences.  A couple of other differences
that might bite you: the snakes don't have HW TLB miss handling support,
the block TLBs have some funky restrictions, and they have the NCR53C700
SCSI controller which is a little quirky compared to the 53C710 in the later
machines.  But none of these are show-stoppers.
