I already found that document, or one just like it, and it didn't really give me any more of an understanding than I had before. SCSI was never my strong suit, as it seems inherently confusing. Plus this whole adapter business is adding an extra layer that I wanted to avoid by buying 50pin drives to begin with.
The bulk of my SCSI knowledge relates to the external end, adding Zip drives and such. I've never dealt with internal SCSI before... and since these machines don't have their original drives, I have nothing to compare it to. I know that the Mac end of the chain is automatically terminated, but... how is the other end terminated? Was that something the original hard drive did? If so, then whatever drive I put in to replace it would have to do the same. Since 80pin drives don't do that on their own, the adapter would then need to terminate the chain (short of attaching a separate device just to terminate the chain).
As for high-byte termination, this makes it seem like it has to do with using any 80pin drive on a 50pin chain. All the adapters I've seen don't say anything about terminating or not terminating the high-byte, and I think that's whats getting me so confused. Do all the adapters have high-byte termination automatically, or is it a feature I have to specifically ask for?
That's my understanding of the situation... hopefully it's accurate enough to make this all work. Otherwise... I'll need somebody to spell it out for me in nice, simple terms that any idiot would understand. [
