Oh, I wasn't arguing with you. I can see how my wording could be interpreted that way though.trag,
That "Note" wasn't by me, it was in FWB FAQ. No reason to argue with me
No, I sincerely meant, that I wish I knew how they did that.
I've known since the days of the Turbo601 upgrade that the JackHammer has SCSI Manager 4.3 in firmware, because the Turbo601 did also and they conflicted. One had to disable it from loading on one of the cards (don't remember which one) in order to use a JackHammer in a machine with the Turbo601 upgrade.
I did read a section in "Inside Macintosh" which explained about CAMs and SIMs, and apparently what one would really need to do to make an IDE card work well on the old Macs is to write one's own stack of SIMs and CAMs, so that multiple disk expansion busses could be supported. Once one understands how, it's probably not too hard to do another one for USB, etc. but learning how to do the first one would be a doozy.
