MKII SCSI Mod.

[ZXoney]

Anyone out there in need of the SCSI mod for a MK-II?

I got one as a bonus with my CSPPC that has UltraSCSI built in, and wouldn't work with it anyway!

Just posted it on ebay so have at it!

Good luck to you all..

Sorry but no, from the picture it looks like nothing more than a termination block on a backplane, I have a 50pin to 25 backplane I'll throw in if you win and want it? Or does this daugther Card do more than give external connection and act as a passive terminator?

This is true most of the time when dealing with the Hard Drive and older scsi controlers like my A3000's, but the resistor array is x# of resistors with only one ground! so no jumper no ground no termination.. I have a few external SCSI boxes and all have a two position swith for termination.. Either way Active or Passive, you can still get internal termination blocks that connect to the 50pin cable to do the same job..

Good point though!

Not so, If you are a "Amiga.org" member I will gladly ship to you world wide! Shipping cost will be actual cost, no handling charges.. I'll do this here because I know its going to a real Amiga user and not some one just looking to get it cheap and resale for more! Lota that crap on ebay!

Good point, I just looked in the back of my CD-R box and the terminator switch runs to a jumper on the drive itself, so I guess that kills the 5v+ and not ground, didn't think about the resistors floating, guess that would cause errors! :bow:

So, the question is can this board be bypassed? And if so how would we connect the active terminators? One on the end of each 50pin connector? Or both to the external?

With both active terminators being connected to the external connecter of this pcb I would think that the internal connecter is wired in next to the controller and the terminators on either end of the chain? So both internal and external devices can be connected to the external connector like this:

internal and external devices being used:

(active term)======(external device)======(SCSI Controller)===(internal device)===(active term)

or

(active term)======(SCSI Controller)===(internal device)===(active term)

for only one device being used?

"===" is of course the 50pin ribbon cable..

So maybe Its active termination on the cd-r and my other scsi externals? I aways thought active termination was for Wide,Ultra, and 320 only, never new it was used in the SCSI-I and II. :-o

thanks for the info!
