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.
> 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.

Right. That's an '040 thing. Motorola never emphasized it until much
later, once Intel began hyping the DX2 line of 486 processors.

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.

I have this old Mac SCSI drive+enclosure, a Dataframe 20 model.
It came with an old Mac 512K that has a 3rd party SCSI card.
I would like to save the data from the drive for archival/historical
purposes, but I am having trouble for several reasons.
In a newer apple laptop, the hd is not recognized at all,
neither by silverlining nor by APS formatter. And I can't
attach the drive to other machines because I don't know how
to set its SCSI ID to something other than 0. The drive houses
an older Microscience drive and a bridge labeled
"SMS MODEL OMTI 3100"; this has, among other things, a Z8
and a 2764. The label on this last IC says "SUPERMAC 3103".
Everything seems to have been manufactured in 1986.
Does anybody know how to set the SCSI id for this bridge?
Will it look like a standard SCSI device to another apple, or
is this a non-standard beast?

I have a 605. It cost me $5 at Dayton. I use it to dump my QuickTake 150
camera and convert the images to TIFF. Can I just drop a full 25Mhz '040
in it and rise above its limitations?
> Any PowerBook
Someone gave me a PB160. It appears to have been dropped/thrown. The plastic
mounting posts on the bottom shell were broken and the guide rod that the
floppy head slides up and down was dislodged from its mountings. Of course
the HDA was roached. It powers up fine, now, on external power (dead battery)
and even boots from an external disk. Any good sources for cheap PB160 disks?
It only needs to be large enough to hold OS 7.5.x and have a couple dozen Mb
left over for the QT150 software.
Thanks,

They found a good place to hid and did. Likely they were there but
now there are more places to hide and maybe other bugs to eat so
they are being fruitful, multiplying and also making a mess.

My Mother had some Dataframe 20s with the OMTI 3100 MFM<->SCSI
card inside.

Not without looking at a picture of the card.

AFAIK, it is just a standard, pre-SCSI-2 interface. You will *not*
be able to issue IDENT commands against it to divine the drive
geometry. You have to _know_ the heads/tracks/sectors of the MFM drive
(there are lists of those out there - I was just looking up the XT2190
today and only found 47 hits with Altavista - it's a good keyword to
use to find MFM drive lists)
The problem is probably the third-party controller. It may or may not
count on a certain set of contents of the first cylinder or two. With
the right driver disk, you could reformat that drive on a more modern
Mac, but you want data recovery.
If you can't change the SCSI id of the Hardframe, why not change the id
of the boot disk in your target Mac?

Hello. I'm new in the list. I write from
Spain; my name is Sergio. I have one question
to somebody that can answer it: Can it be
possible to obtain some sort of info about
"Compatible Time-Sharing System (CTSS)" from
the M.I.T ? I'm interested to do one IBM 7094
emulator and I should like to made on it the
modification that was made in the machine
that rans the CTSS. I think that there was
some manuals from MIT press ans internals.
I suppose that can be possible to obtain
it paying. I should like to hear something
about this.
Same thing is applicable to Multics question.
Somebody is doing a Honeywell 635/645 emulator
like I could confirm one week ago; in this way,
a primitive version of Multics may be sufficient,
I think.
In both cases we think in Java like the platform
to do the work. In my particular case I want to
do some other emulators (Univac I, IBM 701,
IBM 1401 and IBM 650) because I have some info
about them (opcodes, etc). There is only a
question about the Univac I that nobody resolvs:
Can it be possible to obtain a detailed diagram
>from the Main Console of the Univac I ?
Well, that all. Thanks.

Hi all
I have to refer to the collective wisdom of the list.
Here's the problem:
I live in the frozen land of Minnesota, I have a 12'x16' shed full of empty
cardboard boxes, I have a house full (and I mean full) of computers.
Would it be safe for the computers to spend the winters in the cardboard
boxes in the shed?
Should I insulate the shed first?
Should I move to the shed and store the computers in the bedroom?
Thanks
Francois

Not to mention the fact that Mot had bet (and spent) heavily on the
88000 RISC architecture and lost. Unfortunately, the marketplace
wasn't looking for a better design; rather it simply wanted faster &
cheaper.

While the bug stuff doesn't faze me, I should point out
that you should not mess with rodent droppings without
wearing a respirator. Hantavirus, spread though rodent
droppings, is no longer confined to the southwest.

Yes, if it falls over things may break. Apply common sense here. Also

I'd bet 50-100 pounds SQft for really nasty stuff and for a stack of
common
PCs down around 25. The problem is how much can the floor hold? If
it flexes when you stand on it that would be around say 170lb/sqft
(assuming
nominal adult person) and might represent a upper limit.
Temperature is not an issue. Humidity and condensation are big issues.
Some plastics dont age well when hot or get very brittle when cold so
handle with care and avoid the sun (UV). Also sitting for years is bad
for
caps so lack of use can be problematic.
The last problem varies with area but is likely everywhere, Vermin.
