I used to own an external 400k drive, sold it about 10 years ago
along with the old 400k internal drive they let me keep when I
had my Fat mac upgraded to a 512Ke.
Yes, Apple did make an external drive, ISTR is was called UniDrive
but that was also what they called the single plastic 5.25inch drives
for the Apple //e, according to Sellam... So I think Apple may have
goofed and used the name twice. However, these were not Superdrives,
IIRC, they didn't support 1.44MB, only 800MB.
When I first saw it, the sounds it made were like a little hard
drive, or so it seemd at the time.
Third-parties also made external drives; I have one such beast,
can't recall the maker, but I think it has both autoeject in
addition to the quite visible and accessible front-panel eject
button.

U-blew-it is good for that. The marker pen for hand drawing etch directly
is
the ever popular Sharpie (sanford) permanent marker. They are avalable
in many widths and work just fine for resist.
For the Iron look for a low cost temperature controlled iron, it's worth the
price
and usually they have fine tips or can have an assortment of tips.

If your going that fast. Then again I did a UHF transverter using dead bug

Yes, all the really neat new stuff is. However PICs, Amtel cpus, and good

BGA is the extreme and likely more than a trivial project use.

Maybe, maybe not. For the stuff I do, and have done, it's pretty decent.
I've been doing it for over 30 years so I do know the world has changed.
Buying fast logic in 1970 to make a 50mhz freq counter was difficult, now
it's a gimme.
> Programming devices often needs (one or both of) expensive hardware or

If your programming GAL, FPGA, and the like, yes. Eproms no problem.
Then again I've met some that wanted a high end FPGA to do what I can
do in a handful of diodes and a few transistors or less.
>I stand by the "almost impossible" statement above.
You go in expecting defeat and you will be defeated. I just finished
building a PLL system with 100hz resolution at 42mhz in a 1.5inch
cube. No exotica, most parts bought from JDR catalog at reasonable
prices.

Maybe but with the right mindset these are increadable resources. They
allow one to use programmed micro where you needed a dozen chips
or more before.

Not trying to shoot flames anywhere. I'm just voicing my
objection to the naming convention. If I thought it was a
serious problem, I would, as you suggest, bring it up with
the Debian group.

Since it's a cosmetic thing, and has no impact on usability, I've
largely tried to ignore it so far. The system is technically not
harmed by it.

Rest assured that if I ever see Debian make a big technical
mistake, I'll be the first to let them know. ;) The "name thing,"
while it annoys me, isn't really worth bothering Debian about.

I don't disagree, but I believe that, being a purely syntactic problem,
the Debian people have better things to do with their time than debate,
argue about, and perhaps eventually fix it. I'm sure they wasted enough
time (several seconds at least ;) changing the name the first time, since,
IIRC, the old Debian distributions were "just Linux."

Never had a problem with Debian, other than its name...
it always either parses as "of or having to do with Debbie", or
I hear "Denebian" as in "Denebian slime devil".
Is it an acronym for something?

Wow, and on a 3.5" disk too... :)

So dual FDDI just isn't good enough for you? :)

Usually, I could just call up the chipmaker/partmaker and ask
for a few enegineering samples. When a 10MB Irwin QIC drive
stopped working, I probed the adress line on the thing's Z-8
(yes, Z8) processor; there was no change, so I figured it was
toast. Called up Zilog (this was 1987), asked for one, got two.
Pull bad chip, insert new chip, got working Irwin drive.
More recently, though, you have to develop a relationship
with a rep from the local distributer (Hamilton-Avnet,
Meunier, Graham, etc).
WORST CASE was Mitel; I needed parts for a mini-PBX I
designed and then never built. I had to buy this guy
*two* martini lunches before i got my parts. Still it
was a bargain...

I'm not preaching Stallman. What I said is that the better part of the Debian
community has chosen to give GNU credit in the system. You can disagree
with it, and that is fine! The world+dog does not have to think Stallman
is the icon of open source. Go ahead and edit your /etc/issue if it's that
big a deal.
At the risk of being a pedant, Debian is not a Linux operating system; it
is designed to be a universal operating system, that can use any Unix-like
kernel at its core. Debian is being bootstrapped on BSD and Hurd currently.
The core of Debian is GNU system utilities and the Debian policy and package
system, which is why the kernel name is prefixed by Debian and GNU.
Redhat, Mandrake, etc don't bother, because they are Linux systems, and ONLY
Linux systems. They will never be anything else, thus "Redhat Linux" and
"Mandrake Linux" are fine titles; they indicate what the system aspires to
be.
That's the pragma behind it, it's not giving into Stallman's demands and
such, it's just a choice behind the user and developer community that "This
is how we want to present our system as installed by default." They're not
twisting anyone's arm.
