I'm selling a Mac 128 on eBay. The bid is up to about $60 and the
auction ends today. If anyone is interested in it just go to the link
below and bid through the auction. You will have to pay shipping so keep
that in mind.
11941337: Original Macintosh! 128K / KB / FD / More!
Current bid: $51.00
Auction ends on: 04/30/98 18:31:45 PDT
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=11941337
I also have another 128 that seems to work but has a dead screen. And a
pile of the external floppy drives (3 I think). Includes keyboard and
mouse. Accepting offers.
I've never seen an 80W power supply. All original IBM 5150 PC's I
worked on had a 63W power supply and the IBM XT's all had a 130W power
supply. You mentioned your supply has a 220V selection? If so and you
are stateside, make certain it is in the 110V position. If you have a
220V power supply that doesn't have a 110V selection and you're
stateside... you're out of luck. I concur with all those previous
respondents that this supply of yours is most likely good but loaded
down either by excessive loading (more cards/memory/drives than the
P/S can service) or a short circuit in one of the add-on boards or
drives. Just unload until you find the cause.

That's odd. My power supply's 130W. It's also the 220v variety, as that's
what's available here. It was made in Dublin, Ireland. It really looks
like it was how it was made, as it looks REALLY built-in to the case.
Anyway, I can't see any reason that it would be dememanding too much power,
all I have connected is a XT clone motherboard, (however, it WAS sitting in
an XT case) and a XT floppy drive connected. So, any ideas? I think that
it was just this PS's time to go.... and it was two weeks one day older than
I am!
Thanks for the help. I might need a new PSU, as I'm not good at this
type of thing. After testing it with a dummy load, just a HDD, and a FDD
(one at a time), and rechecking all my power connections, I think that it
REALLY is dead.

Yep, Apple Records. Actually, it was founded by Paul Macarthney (however
you spell it) and John Lenon, the Beatles. Their idea was to have people
coming in, and doing what they wanted, getting profits for their records,
and not having to go beg the brass at some corporation. They lost more and
more money, into the 80's, when they were "eaten up" by Capitol records.
The Beatles CD's available now from capitol still feature the Apple logo
(not Apple Computer), and the CD's also have it.

hmm, I've overloaded a standard XT (80W) supply before trying to run a
couple of the original 10MB hard drives (amongst other things!). Guess
it depends on what cards and stuff you're running (some of those old
full-length boards drew a hell of a lot of power...)
I've got an old pre-XT machine somewhere with the 63W supply, I seem to
remember it wouldn't even power one 10MB drive with motherboard and a
single floppy drive in place... I can't remember why on earth I even
tried it though, I don't think the pre-XT machines (what was their
proper title btw?) would even run a hard drive...

Sorry, Sam, what I meant was our systems here are badly set up. And I
refuse to spend hours trying to get WNT to do things properly when it's
probably not capable of it. When I try to use your forms page, Internut
Exploder asks for a directory in which to store outgoing e-mails and

I will get TCP/IP on one of my UNIX boxen at home and get a personal
connection...)
Physical address will follow by private e-mail.

It sounds like a GridCase3. Probably worth $45 easy. That AC module is
definitely worth something. If I hadn't just bought a TRS-80 m600 and a

I finally had enough time today to go to Canadian Tire and pick up a set
of allen wrenches, so I finally pulled the disk drives out of my ailing
Kaypro 2.
I moved the resistor pack to what was formerly drive A, and swapped the
jumper blocks, put everything back together... and it worked! The Kaypro
2 booted up WordStar with absolutely no problems.
Now drive B (formerly drive A) can't be accessed. It gets a "Bdos Err On
B: Bad Sector" on known good disks. So it's definitely the drive that's
bad.
Mechanically the drive seems sound, so I guess I have to assume that
there's something wrong with the electronics. I haven't done a
side-by-side comparison with a working Tandon drive to see if there's any
obvious differences, though.

heres a quick and dirty way to test one:
if you have a hard drive, plug that into one of the power connectors, then hit
the switch. that will let you know if its working or not. this test will work,
as i use an xt supply just to run a scsi drive for my mac when i bring it out

The symptoms you describe could also mean that your disk drive is

It is some years since I looked at the Cray 1 in the Deutches Museum in
Muenchen (Munich), but I distinctly recall seeing lots of 10xxx chips in
it. I remember I had just been given a board from the CPU of a Cyber
two-hunderd-and-something (?) that had been thrown out by Muenchen
Technical University a few months earlier, and this board has lots of
100xxx chips on it.
Philip.
I posted this a few weeks back, but noone answered, so I'll ask it
again.
There is a certain Macintosh 5400/180 at my school whose hard drive
crashed about a month and a half ago. When it tried to start, it
wouldn't really seek, just made a ticking noise and the LED would
flash. So, we took it out, ordered another one. A few days later,
it died the same death. So now we have another one. My ethics don't
allow me to just put in a hard drive knowing it will be destroyed.
What should I do? One hint is that the Macintosh is in a soundproof
booth, and is powered from the booth, which is plugged in. But, the
mac is plugged in via a "surge protector".
Ideas? Could it be bad power? Any way to check?

Could you simply be overloading it? Seem to remember original IBM XT
supplies do this when there's too much load on the system - does the
supply seem to work without anything connected to it? The fan should at
least spin then...
It's equally likely that one of the cards you've got, or the motherboard
itself is faulty in some way and is causing the supply to shut down. If
you've got a voltmeter try checking the output voltages.
Final possibility: did XT supplies have a "power good" reference line
that the motherboard tied to +12V to signal that everything was Ok?
Can't remember if this was only AT systems that provided this. If they
did it may be that your new board doesn't provide it but the power
supply expects it to (wait for someone else's words of wisdom I guess,
been a while since I've fiddled with these things - if that is the cause
though you should be able to simply tie the line to +12V and then
everything should work... :)

Sounds fun!
It occurs to me that I gave a small talk on the Tek 4050 series last
autumn (fall). I'd like to come to the VCF, and I could probably bring
my 4052 and some demo programs, and give an adapted version of the talk

I can't remember who mentioned they had a 1611A without probes, but I
checked it out in the lab today.
The pod with the ZIF socket and Z80 clip does have a little "stuff" in it,
but the "ordinary" microprobes are simply buffered by a little box
containing a pair of 8T37 buffers and a few decoupling capacitors. This
box is connected by a plain ribbon cable to a connector on the 1611A. If
you need to know the connections/layout, I'm sure it would be easy to
reverse-engineer.
