Good day,
OK... smiley aside... why the SE/30? I happen to have one that I
replaced with the Quadra 605. As far as B&W Macs go, it seems
quite nice. Unfortunately for me, I have a couple of SE Ethernet
cards, but none for the inside of the SE/30. I have to use my
only SCSI<->Ethernet adapter with it.

SE/30
Why? Yes, the 68040 is a drop-in replacement for the
68LC040.
I just wanted to make sure that the MacOS didn't freak if it found an FPU
in a box that didn't formerly have one. More of an Extensions question
than a hardware question.
There is information out there about how to overclock
that CPU as well.
Cool. If I run across a 33Mhz '040, I'll give it a whirl.
AFAIK, the 68LC040 in your Quadra 605 actually runs at
50MHz internally, but
on a 25MHz external bus.
Right. That's an '040 thing. Motorola never emphasized it until much
later, once Intel began hyping the DX2 line of 486 processors.
Sorry to hear about the abused PowerBook.. :|
At least it was free (to me). I'm still looking for a 120-200Mb SCSI
disk for it for less than a buck a meg.
My Mac experience goes back to the 128K model (a buddy brought one to
work in 1984 when disks were $5 each), but is spotty. I used to support
my mother's business when she had a room full of Mac 512Ke machines with
Dove Snap boards (memory and SCSI), Mac Pluses and Mac SEs. Her most
powerful Mac was an SE with 4Mb of RAM and the original 18Mb disk. She
used them until she closed her doors in 1997. I skipped several generations
of hardware until the IIci and the Quadra 950, and have missed most of
the PowerPC stuff.
Fun boxes that still have their uses.

Hello,
OK... smiley aside... why the SE/30? I happen to have
one that I
replaced with the Quadra 605. As far as B&W Macs go, it seems
quite nice. Unfortunately for me, I have a couple of SE Ethernet
cards, but none for the inside of the SE/30. I have to use my
only SCSI<->Ethernet adapter with it.
I like the SE/30 for a number of reasons. One is the original compact form
factor, other reasons include:
Memory expansion. The SE/30 has eight (8) sockets for 30pin SIMMS. I have
heard that the hardware will support 128MB of RAM, but I have never seen a
single-height 16MB 30pin SIMM in my life. I populate mine with 4MB SIMMS, for
32MB of RAM total.
CPU/FPU compliment. The 68030+68882 FPU combination is pretty quick in MacOS
7.X, and allows one to run the *nix like OSes like NetBSD or Linux.
SCSI. Sure it's like a belly button on a Mac, but gosh is it ever nice.
1.44MB Superdrive. better capacity and PC compatability. Mmmmm.
Fan. It has one.
ADB keyboard & mouse. The SE/30 has two (2) ADB ports.
Now this is a rumor that I read on lowendmac.com - but it's been said that you
can replace the SE/30 ROMs with ROMs from a IIsi, which will allow the SE/30 to
run 32bit clean with no extensions. Apparently other fixes also. Can anyone
confirm or deny this? Might someone be willing to supply me with a IIsi or set
of IIsi ROM images so I can burn a set, try it out and report back?

But the ROMs in a IIsi are 4Mbit, square 44 pin SMDs. That's
a delicate surgery you are talking about.

Some also had a rom simm, but I think more common is to rob a IIfx rom simm.
