Well, since the Mac Quadra 700 is of 91 vintage, it looks like I can ask
questions about it...
I found this on teamexcess.com -
ST15150N Seagate 3.5" 4.3GB 1.6" Half Height SCSI H-ST-15150N
Narrow 50-pin
Assuming the jumpers are set correctly, should this work internally in a
Quadra 700?
thanks,

It should, but I don't have a lot of confidence in old Seagate drives.
BTW I even have a "real official" Micronet I think brand, drive carrier for
a IIci/Q700 etc that holds a 5.25 half height drive.

Altas II as one suggested is still bit hot running HD than most
modern HDs. Btw it is 5 years old HD era. Find a way to have small
fan blowing along the bottom where logic board is.
Best choices is newer last generation 5400rpm SCSI drives with dense
per platter w/ large buffer size. Or much newer 2 or 3 years old
7200rpm SCSI drive usually are better specs and is cooler.
Actually Fireball ST SCSI is best choice for this IIci. It will max
out the IIci's scsi throughput.
BTW: Ford, I'm very interested how Micronet designed this unique
carrier to fit huge 5.25" HH drive in a little IIci. Describe how,
photos of on it's own and installed in that IIci would be helpful.
Web or by email attachment.
This is part of this interest because I'm expecting
IIci in the mail in about two weeks with other parts.

The top section the hard drive goes in is rotated 90 degrees, and has a
slight downward tilt, otherwise its the same size as the normal plastic
carrier for a HD and floppy.
Once I am a bit less picture challenged I will put up an image and post a link.

Hey I have a Mac quadra800 on the east coast if someone
wants to take it away. It is a discard system still booting up
nicely with a log-in lock on the disk.
Either help me get it running (reinit disk?)
or you can just have it.

John,
Nice Q800 find! Is someone have claimed it yet?
I would like it for shipping if you wish to let it go. Yes, you can
reinit the HD w/ downloadable HD SC formatter 7.3.5 on a bootable
disk. It comes on a 1.44MB image, you can use rawrite (from linux
sites download areas.)
OS 7.5.3 and updater to update that to 7.5.5 is free to download but
requires a way (bit tedious and somewhat hard way) to get them onto
Mac if you only have a PC. About 19 images plus 3 images. Whew.
Cheers,

ST15150N Seagate 3.5" 4.3GB 1.6" Half
Height SCSI H-ST-15150N
Narrow 50-pin
Assuming the jumpers are set correctly, should this work internally in a
Quadra 700?
Having had personal experience with this drive ...
Yes, the ST15150N will work fine in a Q700. However, it's a half-height
drive. In my Power Mac 7300, the drive overheated within weeks and suffered
a complete head crash. Since a Q700's case is the same dimensions as a Mac
IIci, there's not a lot of clearance or ventilation space for this thing and
it runs *very* hot. If you want to use this drive -- and mind you it's very
fast, despite the heat issues -- you will almost certainly want to add
another fan or run the machine with the top off, or it will fry.
I would strongly advise finding a third-height drive like an Atlas II.
These are fast 50-pin drives (I replaced my Seagate ST15150 with an Atlas II
in that PM7300) and they don't have considerably better heat tolerance
because they're smaller and have more room to radiate it.

It's a nice drive, and it should work with your machine, but it has
nonstandard mounting holes.
Peace... Sridhar

it'll work just peachy :)
you'll need to use FWB or another 3rd party HD toolkit, apple's HD
formatter won't work with that drive.

*snorts!*
In this case one must buy expensive drive init/mounter utility
program. Not worth it on small scale few runs especially with
aucient stuff. But very useful for using optical drives and cdrom
drives.
Yet, there is a "free" solution but you must do it yourself because
apple doesn't allow anyone to download hacked HD SC formatter
program.
Begin searching for the HD SC 7.3.5 formatter patch info, it will
detail how to manually patch it with free editor also from apple too.
The mod is only a hex and easy to find to mod on.
Both unmodified formatter and the editor is available from apple
download section, easier to find them by engine search.
With my patched formatter, can init any SCSI HDs including my elite
1 and fireball ST 3.2 GB and many, many different non-apple scsi
drives.

Don't you just love the way some stupid mailers find it fitting to quote

There are free tools available for download which don't need patching.
One utility which I've got stuffed away on my hard drive is Micronet SCSI.

That single thing, more than anything else, turned me off of
Mac's for a number of years. There's absolutely no reason, other
than greed, that Apple's hard disk utilities shouldn't be able to
deal with pretty much any drive you toss at it. Afterall, look how
flexible the Amiga's disk tools are. Thankfully, this particular
problem with non-Apple hard disks has been cured and Apple ships disk
tools that are capable of dealing with most any IDE drive, though
there are still problems with SCSI drives since the new systems don't
ship with SCSI. I myself use FWB Hard Disk Toolkit for any SCSI disk
with any of my Mac's.

New subject: ? Digital Heddles: Jacquard loom and card decks ?
Hi,
OK, I'm after the really old stuff. The card deck for the Jacquard Loom
inspired Babbage to use it as a programming device and is the precursor of
the Hollerith card. So I've been trying to locate some old Jacquard Loom
card decks and maybe even an abandoned loom to add to my collection and
show to my students. Lots of 19th Century Jacquard weavings on eBay but
never any cards. A web search reveals that some company's will still punch
out cards for Card Jacquards, but would rather create floppies for
Electronic Jacquards. Indeed it would be nice to have an example of
each. Does anyone know where any of these devices might be had for
scrap? I've made some attempts to contact weaving companies, but as you
might imagine they have more important fish to fry than supplying
collectors with their discards. So before I get really serious and begin
making long-distance phone calls and personal visits, I thought I'd ask if
anyone on the list could provide me with a few pointers.
Anyone else interested in Jacquards?
Cheers,
Nick

Indeed it is, but it is a little incorrect to speak of a "Jacquard loom"
since the automatic shedding mechanism known as the "Jacquard machine"
may be mounted on any loom. and is distinct from it. As a handweaver of
27 years standing, I just *had* to throw that in :-).
As far as finding a working (or even non-working) Jacquard machine and
cards, your best bet is probably England, where the semi-automatic
weaving tradition is still alive in places like Bethnal Green. Peter
Collingwood or his son <peter(a)plysplit.demon.co.uk> may be able to point
you in the right direction overseas, and here in the US, Bill Koepp
<bgkoe(a)ncinternet.net> may be of help.
Unfortunately, many of these older weaving devices are long, long gone
and even the presently operating mills don't even remember them. I
remember talking with a man who graduated from the textile department of
NC State back in the sixties, where the students amused themselves by
throwing old mechanisms like the Jacquard out third story windows!
