 Yes. Thats a typical problem. The 53C??? might be a good candidate.
 AFAIK it contains a RISCy processor and is quite far programmable. Once
 I got a AlphaServer with PCI DSSI cards. The DSSI was implemented with
 53C525...
 It would be especially interresting if the SCSI chip of the Sun ELC is
 capable of implementing a target. The ELC board isn't that large, fits
 in an external SCSI enclosure, can be driven with a 5 V / 2 A PSU, is a
 very nice piece of hardware, boots NetBSD nicely over Ethernet and
 would be able to do that iSCSI trickery. I have several ELC boards
 around from machines with dead CRTs. In the days of NetBSD 1.5 or 1.6
 I built a CDR copy applience out of one... 
 
  I once built a card cage (out of wood ;)) that held a row of ELC and
SLC boards.  It ran a bunch of services for an ISP.  That setup worked
amazingly well!
