NEVER attempt to load a pack if you haven't inspected it AND the heads first.

Was this combination ever known to work?

You now need to throw that pack out, and thoroughly inspect and clean the heads
and any pack to attempt to use in the future.

You also need to inspect the filter, purge the air filtration system if you 
haven't done that already
along with cleaning the filtered air path in the drive
and run the spindle for a while before attempting to load the heads again.

The only thing that comes to mind is the servo system is going to be extremely

If you get back over there, try to find CDC ID tags on the drum and controller.
There would normally be a model number badge somewhere on the outside.

It isn't. I've asked Ivan and he hasn't been willing to release it, mainly

Yup, in both directions.

People seem completely clueless about what a reasonable offer is, on both sides.

The cheapest listings are BIN, and are very efficient at getting rid of things.

To put it bluntly, I list high and expect reasonable
offers, which rarely happen.

Sometimes I guess low on the BIN price. If there are an insane number of views
and no one bites, I RAISE the price. Eventually, someone buys it.

If something isn't moving, I kill the listing, lower the price, and relist.
There are no cost to do this.

I see a few people abuse this, relisting every couple of days to keep their junk
in the new listings.

In my opinion, eBay's fixed-period auctions are a waste of time.

Harvard had an SDS 940, which shipped with a version of Berkeley's timesharing

"Super BASIC". SDS's OS was replaced with Tymshare's at Harvard because the

Ferractors.

While computers now are composed by many integrated circuits containing each 
millions of logical units,
processing data with a speed of a few gigabits per second in a parallel-flow of 
64 bits,
the USSC's CPU-logic was composed of over 1000 circuit boards with each only a 
few active components.
One circuitboard contained only 4 simple logical units, the ferractors.
These circuit-boards processed the data with the theoretical speed of 700 
KBits/second.
The ferractors were tiny transformers, performing one-bit operations, powered 
by 700 KCs AC.

On the positive half of the cycle, the ferractor-core was magnetised or not 
depending on the current through the bias-coil,
which made the total magnetic field in the core to exceed the 
hysteresis-threshold or not.
In the subsequent negative half-cycle the ferractor showed on the secondairy 
coil a high or a low impedance,  depending
on whether it had been magnetised or not.
On low-impedance a positif bias-current was generated for the next 
ferractor-circuit.

Since each ferractor was set in one cycle-half and was read in the next 
cycle-half, an one bit-stream of a register was
formed
by 24 ferractors in series, alternatingly fed by opposite phases.
In such a string of ferractor-circuits 12 bits cycled around, 10 bits, a sign 
and a space.
The information in the registers was circling around in 4 parallel 
one-bit-strings.
The data in the registers cycled around with the same speed as the information 
on the drum-memory.

The 200 diode-boards were used in OR and in NAND functions, depending on being 
located in the positive-phase-circuitry
or the negative-one.
The bias-coil was connected in positive or negative polarity to enforce or to 
diminish magnetisation during the first
half-cycle
in order to create normal or inverting logical gates.

Not that anyone seems to collect printers, but the LBP1 and the Canon engine

first 'inexpensive mass-produced' laser printers.

I don't know of any that still survive.

Before that, if you were lucky enough to be at Stanford, MIT, or CMU, you could 
use the Dover
and Altos that were part of Xerox's University Grant Program. Copies of 
well-known papers from the early
80s are very distinctive because they were printed on them.

Eventually, the Dover was networked to other computers. Stanford had a rather 
big 3mbit research Ethernet
made with SUN board gateways.

Not that any of this has much to do with Sun-3, other that it was possible to 
plug a SUN 3mbit ethernet
board into one with a Multibus adapter. I had packets coming out of a Sun-3 a 
VERY long time ago and
still have a bunch of the 3mbit Multibus boards.

I went a little crazy and started doing the same in 2017 to dump the firmware

I ended up scrapping most of them in the fall because they were

For some reason, they think the classic fonts are ugly and replace them

Electronic Design Automation
The S-1 project to build a supercomputer was started by the astrophysicist 
Lowell Wood at the Lawrence Livermore
National Lab in 1975, first ran a program in 1978 and continued until 1988. Two 
Stanford students, Tom McWilliams and
Curt Widdoes, were recruited to develop SCALD (Structured Computer-Aided Logic 
Design), an influential language to
design computers, written in Pascal on DEC's PDP10  SCALD was based on the 
Stanford University Drawing System (SUDS)
developed at Stanford's Artificial Intelligence Lab (SAIL) first by Phil Petit 
in 1969 on the PDP10 in assembly
language) and later by Richard Helliwell. Petit moved to DEC and used SUDS to 
design the DEC KL-10 of 1973. Therefore
SUDS became the first Computer Aided Design (CAD) system used to design an 
actual computer. Later Bechtolsheim used SUDS
to design the SUN boards at SAIL. SCALD jumpstarted a whole new field, 
Electronic Design Automation (EDA) for electrical
engineering and electronics. Tom McWilliams and Curt Widdoes started a company, 
initially called SCALD Corporation and
later Valid Logic Systems, in 1981 in San Jose to sell SCALD on a proprietary 
UNIX workstation. At the same time, also
in 1981 but in Mountain View, Aryeh Finegold and David Stamm used the 
public-domain source code for SCALD to found Daisy
Systems, that also required a specialized workstation running its own Unix-like 
operating system. Several notable
Silicon Valley founders (e.g. Vinod Khosla, Harvey Jones, Don Smith, Tony 
Zingale, Mike Schuh, George Haber, Dave
Millman and Rick Carlson) started out at Daisy Systems. The third pioneer of 
EDA was Mentor Graphics, founded in 1981 in
Oregon by Tektronix engineers (Tom Bruggere, Gerry Langeler and Dave 
Moffenbeier) and the only one that didn't require
specialized hardware (it ran on regular Unix workstations).

TOS shirt on someone who looks like Carl Helmers in 1976?

Find someone that can draw, or get serious about Cubism.
This just looks stupid.

SUDS (Stanford University Design System)
also used to design the Livermore S-1

Modified version used at MIT for the CADR

still lives on at XKL

Been searching for the Stanford/MIT SUDS and the Livermore SCALD tools for 
decades.

The DEC SUDS may be somewhere on the DEC LCG backup tapes.

Looking for Heath H-29 operation manual and schematic

[Al Kossow via cctalk]

Just put a working one together from parts from two different auctions and
I'd like to find the rest of the documentation.

H-19s are pretty common, H-29s not so much so. Haven't been able to find the
docs on line anywhere.

Re: Looking for Heath H-29 operation manual and schematic

[Al Kossow via cctalk]

Thanks for the help. The only tricky part will be that the schematic is larger 
than
11 x 17

Need to get my blueprint scanner working.

Little concrete analysis has actually been done on these drives that has been 
released outside the
drive recovery shops.

I would suspect the heads themselves before the preamps.

I have been told a common failure mode was for them to open. Maybe something
bad happens between the platter and head over time (metal-metal corrosion)?

And who knows what sort of nastyness happens if the two are in contact for
extended periods of time in the presence of humidity.

floppies recovered and uploaded to http://bitsavers.org/bits/HP/HP_9000/cpm-68k

I'm pretty sure this will only work in a 9121 single-sided drive but I'll be 
trying
to boot it soon

Looking around after purging about 100 dead drives a few months ago..

The VT-11 display processor stayed exactly the same, they just changed the 
processor it went into.

There are brochures for the GT-44 and 46 on bitsavers

GT41 is a GT-40 with a desktop 11/04 chassis
