My original question:

The general consensus is that there exists no such product. Most people
suggested that I use an SBus/VME adaptor. One other person (Aydin Edguer)
mentioned an Adaptec SCSI/SMD card. Half of the messages I got were
"Me Too!" messages, which is common, when I exhaust all other channels
to post a question on sun-managers (or is it "sun-emergencies" now ? :-)

Here is a summary of the responses:

According to the August Sun-Flash SBus List from (July 30, 1991) there
are no such products available. There are however a number of SBus-to-VME
bus adapters which might help out.

Performance Technologies is selling an SBUS-VMEBus adaptor and a
driver that purportedly will work with a Sun-supplied VME Xylogics
driver, etc.

One way I've seen is to get an SBus to VME converter. Some drivers work
with them, some need mods, but I have seen it done.

This is a good question since Sun will stop support of SMD with
SVR4, even with their VME based server models.

Solflower corp has an SBUS-to-VME card which should let you use your existing
VME-bus SMD controllers.

There is no such thing in the current Catalyst listing; the closest
one could come would be an SBus-VME adapter chassis, then a regular
VME SMD controller card like the Xylogics 753.

Given that SMD is pretty much dead these days, there doesn't seem to
be much incentive to develop an SBus card, but I could be wrong.

        I was just reading through the comp.periphs.scsi newsgroup and
came across the following article. While it is not an SBus SMD controller,
it would at least let you use your drives on the new SPARCstations...

- The Adaptec 5580 is the card you need. I just bought one from Mike Mak at
- Weird Stuff Warehouse in Sunnyvale,CA. (408)746-1100. It cost me $80 plus
- shipping and he has more. The board can control 4 SMD drives if the "A"
- cables are daisy chained. The board outputs a 50 pin (male) Centronics(?)
- SCSI port. I haven't got it working yet because I'm awaiting power specs
- and a Centronics to SCSI cable. The power looks like standard PC power
- supply plug.
