My name is at the top of the list for a Stratus high availability server that
is going out of service.
Is there anyone here interested in these machines?
This has dual G86010 cpu's, expansion cabinet. It was recently in use as a
test switch for an ATM network.
There is a second machine that will be available in a years time.
Is it a simple task to switch a machine from 220 20a to run off household
current 110 15a?

do you mean 68010's they had systems with 68K's and
also with 88100's (almost the death of them, they believed
Motorola's BS about the 88k)
The periperherals they used were 110, so should switch. I don't
recall whether the actual PS modules were or not.
A lot of these machines had to be made 220 because UL got a wild
hair up it's butt that you couldn't run 30 amps of 110 thru a metal
bulkhead safely, so to run these cabinets, each bay needed 220 / 20 A
but the insides were frequently designed before the 220 requirement, so
you get some wild wiring on the AC of some boxes. I know that there
were a lot of Honeywell Level 6's that had 220 on the back but were
all 110 inside.
Note: the cumulative power was 30+ amp at 110, but if you could have
run 3 extension cords to one bay (also a no no) there would have been
no problem. So you had to run 220 thru the bulkhead and break it
up.
This only applies to 220 2 phase type power, not 208 3 phase, which is
different. Most of those systems have no 110 in them at all.

Errr.... 220V comes in single phase and three phase flavors. While I
believe 2 phase power does exist, it's somewhat esoteric-- I've never even
*heard* of one, let along seen one.
208V 3 phase is 110 between any one phase and the neutral. It is *not* 220V
between any two hot wires, but if the PS is merely dividing the two hot legs
into two seperate 110V circuits it should work fine.
Note that three-phase power is not very common in residential installations.

There once was two phase - four wires with the phases 90 degrees apart -
but it is basically "gone"* now. A few big old Navy radio transmitters
from the 1920s used in for the motor-generators.
*It may still be held on in old factories. Remember, New York City *just*
discontinued DC power distribution!

And a center-tapped grounded conductor for two phase five wire is what I
read about in skool. At least now I know what it was used for!

The last time I installed a service (1200A 208V 3P w/ 400KW backup genset
IIRC-- very interesting!) in Dayton, Ohio the power company service handbook
made the assertion that they were not taking any new Edison power customers
but made no mention of how many, if any, were still on the books.

New subject: Atari ST spares
Hi folks,
Just wondering if any UK list lurkers and regulars have a keyboard and
floppy drive for an Atari 520STfm? Got one here that's had An Incident with
its keyboard and has been repaired in the past but has since gone bad again,
but it appears that the floppy is toast since it continually tries to seek
track 0 and won't read/write even Atari format disks.
cheers

Well I'm not in old blimey, otherwise I could offer a KB.
The ST floppy drives have been the bane of my Atari ST
existance. There must be a multitude of STers out there
that have tried to reform these beasts. At some time I'm
going to get serious about reclaiming them, instead of
simply replacing them. I did restore a couple by fiddling
around with the heads, even without a scope or timing
disk.Which gave me a couple of more years on 2 of them,
but of course they eventually failed again.

Atari could screw up a one-car funeral man. I love all their gear, but
the ST's are weird with floppy drives. How did they manage to get all
of the ST machines to keep the drives ON all the time?
Geez.

jeff

I'm not shure, but wheren't the floppy select signals also
generated by the keyboard controller?

They were/are on the Amiga (Paula) but I'm not sure about the ST. I'm
hopefully getting another ST this week, and I'll also play swapsies with the
museum's ST to see if the keyboard is breaking the floppy. Nobody mentioned
that on comp.sys.atari.st though.

Yeah, you're right, I mixed them up. The Atari keyboard controller
is only responsible for keyboard/Mouse/Joystick and RTC (except
Mega ST, where a real RTC is build in).
