This particular manifestation of a hard drive problem is not classic,
but since it could just as easily happen on a classic computer, might
as well ask it here. If you think it's inappropriate, please say so.
The machine in question is a Mac Quadra 610, which has been running
as a fileserver for a 15-machine network for many years. It has an
8GB hard drive, probably one of the first to get into catalogs. It
was working OK, but tended to freeze when four people started to
transfer 10MB files. So, we replaced it. And now, the hard drive
stopped working and we can't get the documents stored on it back.
Here is the hard drive problem: it spins up ok (takes about 15sec.
and sounds like a hair dryer when it does), and then tries to seek.
The heads sound OK for about 1 sec. and then make a clicking noise and
stop. It then tries again. Does this mean some servo data has been
overwritten or something? We don't want to spend $1000 on recovery, and
I thought this might be a good time to try some alternative methods.
Would it help if I opened the drive and manually moved the heads?

Probably all that's wrong with it is a blown fuse. (that happened to a
TRS-80 Model I P/S that I had). To get it open, take a utility knife (the
kind with snap-off blades) with a new blade, and a blow torch. Use the
blow torch to heat the knife, then "cut" around the P/S until the top half
pops off the bottom half. I use this method to open old laptop batteries
to replace the cells. When you get the P/S fixed, just put the two halves
back together, (sand [or cut] the ridges off made by the hot knife, first)
and put a bead of hot glue in the seam to hold it together. It doesn't
look that bad, and It can always be popped apart with a screwdriver if you
need to fix it again.

John Wilson does have self-bootable Fuzzball images on ftp.dbit.com,
in /pub/pdp11/fuzzball.
Fuzzball is an "operating system" of sorts, but you can't do development
with it unless you have the RT-11 macro assembler, linker, and other
program development tools, so there isn't a lot of interesting stuff
you can do with it unless you've also got a RT-11 license.
TSX+ is pretty much the same way - without the RT-11 utilities you're
dead in the water.

OK what is an IBM 5363 II? I found one in a trift store.
I've been told that the 5363 was a S/36 that designed to be a very low
cost entry into the 3X architecture and that it runs an operating systems
called SSP. So what is a 5363 II and what OS does it use? Is it worth
picking up and saving? Also does anyone know how to get around the password
protection?

I don't think so, since some of Fuzzball, if I remember correctly,
is built under RT-11 and runs under RT-11. I don't think I've seen
a Fuzzball system which was entirely self-bootable. (Maybe John
Wilson can answer, since he's done some stuff with it).

Arrrggghhh...
Okay, so, for some time my Apple ][ collection has included a //c which I've
never booted because I didn't have the brick for it. I've seen them for
sale all over, but always for $25 to $40 (plus shipping). Since that's like
five times what I paid for the CPU, I've been pretty reluctant to go for it.
At the VCF swap meet, I picked up a //c with brick for $15, and the vendor
even threw in a non-working //c for parts (cool). I brought it all home,
fired up the two good //c's, and then turned to the non working one, which
promptly (auugh!) ate the brick.
I'd like to get in there and see if I can fix it, or just rebuild it (but
I'd still like to at least rebuild it inside the brick case). Does anyone
know if there is a way to get these things open without ruining them? I've
pushed and poked and prodded with no luck.
Thanks a lot!

World Power Systems: Memory boards, big ads, great prices, non-existent
company. Some guy named "The Colonel" who of course wasn't. Magazine ads
on credit, graphic design for said ads on credit, prepayment from customers
never returned.
Not just in Byte magazine, also (at least) kilobaud and Interface Age, year
was 1978? Whole thing was blown by the editor of Interface Age, who was
suspicious and called to "do a story" on the company. When he showed up,
"The Colonel" was on the lam, and there was nothing but an empty office and
a phone.
An almost identical scam happened in, as I recall, 1979, when a company
placed multipage color ads for a bunch of really cool, inexpensive TRS-80
Model 1 peripherals in 80 Microcomputing Magazine, then disappeared.
And let's not forget Morrow, which, after changing names to Xibec (Xidec?)
and announcing & taking orders for some super doozy computer called The
General, also vanished overnight.

What was the nature of this scam?

Here's the information about pricing on the F14 CADC directly from Ray

And on some of the applications the AMI 7200 & 7300 microprocessors made

Could someone post the jumper settings for a RQDX3 controller? I've been
trying to use my RQDX2 docs, but that won't cut it, and I can't find
anything on the net.
