Q1) Termination. As we all know, the Cyberstorm controller has no terminator. For this reason I
put it in the middle of the chain. At one end of the chain I put a Quantum Atlas 2 HDD with
Termination Enabled. At the other end a Fujitsu MAH3091MP. This HD is a LVD drive, but can work
also in SE mode. However, it does not have a TE jumper,although it has a Term Power enable
jumper. This would mean that my chain is not correctly terminated! :-( However it worked nicely
for years! How is it possible? Am I in danger of some hardware damage?
Q2) TERM Power. Here I am puzzled. How should I set TERM Power? The Cyberstorm docs says that one unit should provide TERM Power(I guess the Cyberstorm itself doesn't). The A4000T doc does not mention the issue, while WarpEngine can provide TP. In one chain, how many units have to provide the power?

I seem to remember from the time when I sat up my SCSI chain (1998) that the documentation of my CyberstormPPC said something like "do not use the internal terminators of the devices - use external, active terminators instead".
That's what I did.
My chain looks like this:
act. terminator -> 160gB IDE HD via ACARD UW-SCSI to IDE bridge -> 4.3 gB UWSCSI HD -> CSPPC -> IDE DVD-RAM via ACARD UW-SCSI to IDE bridge -> SCSI II CD-ROM via UW->SCSI2 adaptor -> SCSI II CD-RW via UW->SCSI2 adaptor -> SCSI II tape streamer via UW->SCSI2 adaptor -> UW to SCSI2 adaptor, actively terminating the upper 8 bit -> slot bracket -> ext. SCSI 2 scanner -> act. SCSI 2 terminator (actively terminating the lower 8 bit)
