The adaptor card is parallel to the motherboard (horizontal) and the
Powercache card is mounted at about a 30� angle.
It looks like it's supposed to be that way, nothing is bent or
anything and it has to be that way to fit under the tray that holds
the hard disk and floppy drive.

Not really, just set it there to see if it would.
Also set it on a PDS slot on a IIci to see if it would fit there.
Didn't actually seat it at all.

Nope.

So that supercedes/overrides the 68020 chip?

A manual?!?!?
I can't even find a website for DayStar..... :-(

Yep, easy.

It had a Radius Mac II Full Page Display card in it and I just happen
to have a Radius Full Page Display. :-)
(Rescued that from the dumpster a few months ago!)
Strange plugs on both but they fit.
The monitor lights up so I guess it works......

There's no hard drive or floppy in it so should I just 'borrow' a HD
from one of the IIci's?
Will the II run on 7.6.1?

Lobotomize, interesting term considering I didn't understand anything
you just said except lobotomize!

What??

All soldered.

Not, no room at all on the thing.

There's a big gold Motorola chip that says MC68030RC338 on it and a
smaller Motorola chip that says XC68882RC33A
There's also 2 Texas Instruments chips - 127CN and a mess of Korean
chips and 4 more Motorola chips about the size of the chips on a RAM
SIMM and then a lot more small square chips with yellow labels pasted
on them with various numbers on them (802, 812, 822, 833 etc.)

I found a website that has the manuals and software so maybe I'll be
able to figure out what you just said!
But I take it this is a GOOD thing to have in the machine?
Somebody had to add it later?
I can't believe the school would do something that 'risque'.

Think it'll run on 7.6.1?
That's the oldest system I have handy but I suppose I could see if
any of the 40MB hard drives I have in my junk box work and what
system they have on them or I could install a fresh system using IIci.
I have no floppy that works at all except for the one in my 6400.
(At least I THINK it works, it did the last time I used
it.........around Christmas I think........)
But that's a superdrive or whatever it's called.

That website I found, <http://www.linkology.com/daystar/>
gave me the software but I can't find a manual, bummer. :-(

Well, instead of stumbling blindly I'm now just staggering blindly.  :-)

Thanks for the help.
If/when something happens, other than the monitor lighting up, I'll
let you know.

This IS a 'worthwhile' waste of time isn't it?
Please?  :-)
