- Deja vu. Look at your A3000 motherboard and see if it has terminator
- SIPs. If so, remove them, because they are now in the middle of the SCSI
- bus. If I've got it right, the SCSI bus would (and should) then look like
- this:
-
- Quantum(terminated)-->A3000(unterminated)-->Syquest(terminated[active])

- You should probably also check for the A3000 supplying termpower to the
- external DB25 connector. With the A3000 on, *carefully* check pin 25 of
- the DB25 for +5V. Without this, external devices are not going to work
- unless they can supply their own termpower.
