sure you can,
we just need to make a proper diagram that tells you EXACTLY what wires to ground... and what wires you solder to the SCSI chip.
then you can just have one internally.
well, also need to type out and say what exact parts you need to change in your PLUS PSU in order to have enough power for a HD.
once we have that exact info documented anyone who has a plus can install a hard drive internally.
But right now all we have is some random pictures of people that have already modified it... or bought it already modified,
nobody has stepped up and said, this is what you exactly have to do, step by step in detail.
I am close to doing this my self... but i would rather someone who has already successfully done this save me a boat load of time and frustration.
this clipper thing is honkey and kind of stupid anyways.
i mean you still need to get power for the hd... that off the bat makes it not worth it for me.
Trust me... i have a 100m zip inside of my 512ke /with scsi mac snap, and that booting up on its own w/o a floppy, really is delightful. I would assume i'd feel the same delight with a plus /with 4mb ram. and a 500mb hd... or 73gb 2.5" 10k rpm scsi drive!!!!!!

i already know they work externally, thanks to marky! so i know it will work internally! as long as i can supply it with the right amount of power.
