I suppose the analogy is
Spaceball : "3D-Spheric-Mouse" :: IBM Pointing Stick : Trackball

force sensors should cause less RSI since the hand never needs to move. with rotation sensors, the ball can "keep spinning", which wouldn't appear to be useful.

it is not needed; the symbol index is always updated.

I think of it as an elegant solution to the common guessing game called "did the machine buffer the keys I just typed, or were they flushed?"

I have a thermal paper terminal with a 300 baud acoustic coupler. it was modified to add a serial interface for some type of minicomputer.
it's from 1971, about a decade before the popular TI Silent 700 terminals that did basically the same thing.

not as elegant as a Brunsviga...

This is so off topic, I love it :)

related to the Library of Congress and paper tape as a storage medium:

not sure on the exact design, but from the description of the prototype the rollers do move slightly and use a hall effect switch to detect film tension. so the "dancer arms" are present, just with very short action. It seems like an attempt to contrast the design to a Geneva loop.

for an unpartitioned disk you need to run fx first to install the disklabel.
see http://www.futuretech.blinkenlights.nl/6.5inst.html specifically the section "For systems with the 64bit ARCS PROM"

Please spare a thought for the poor patent illustrators. The job is already very constraining, but at least for mechanical patents they can deploy their skills at shading and complex details. Software patents only have horrible little boxes and arrows, it's enough to make a man jump out a window.

there are binaries on the net for Csound, tiMIDity, Rosegarden, Cecilia, CAST, cmix, PD... maybe some of them are dead links now.

Van Jacobsen's 1988 traceroute used UDP probes.

just guessing, but nslookup uses its own internal resolver, not the system resolver library. so it's sometimes the case that lookups happen differently (and not surprising that lookups done by nslookup don't enter the system's address cache)

It is by will alone that I set DCL in motion.

XFS volumes created with later versions use version 2 directories by default, which cannot be mounted by IRIX < 6.5.5.

it appears to be a Voltage Regulator Module, also called a Point-Of-Load converter. perhaps it slots near the CPUs.

OS9 software is not supported on any Intel Mac, or even on PPC under 10.5. You would need to use Basilisk or SheepShaver and accept reduced device support.

I've been looking at oxalic acid, and phosphoric acid, as well as electrolysis to remove rust from tools. it may be possible to use similar techniques on metal computer parts, as long as they don't contain electronics or plastics.

searches for "SGI" also turn up lots of buddhist paraphernalia.

There's a product called "Rust Free by Boeshield" that is almost 100% phosphoric acid. You need to be careful since after acid etching, metal surfaces are not passivated and will quickly rust in the air. So some kind of passivation (pickling bath) or surface treatment (motor oil, waxes) must be used right after rust removal.

a lot of discussions online these days about JBC stations, they have very impressive heat recovery, sucking something like 140-170 watts when cold started, and reaching 400 C within a couple of seconds. that's ten times faster than my Hakko 939.

Weller also has some amazing (German-made) products these days, like the WHS-M and WD1000-M, with very fast thermal performance.

What are you using for the argument? Too large a number won't be representable as a fixnum.

when the code is interpreted, there is no VM; the interpreter simulates the effect of running the code by means of its own data structures, called "environment objects". To reference a variable, it will make several function calls: to locate the symbol in the current environment, get its value cell, and access the value. In addition, the interpreter is self-recursive, and calls itself on every subform that it evaluates. So your function that loops 50 million times could (on one implementation here) result in calling the interpreter 350 million times.

A CL interpreter has more to do, since there can be symbol-macros and handlers and restarts and things that need to be managed. Those always need to be checked, even if the code doesn't use them. For these and other reasons, most developers always compile their code before running it. (Compiling also lets you see warnings about mistakes in your code!)

18e is very old, and is unsupported by several common packages like ASDF.

SBCL on IRIX would require a port, since it has never run on that flavor of Unix. Maybe a month's work?
The MIPS compiler backend would also benefit from an update to 64-bit, which might be easier, and allow some version of CMUCL to link to modern N32 libraries.

bring out the 2:
π = 2ln(i)/i

π/2 = ln(i)/i

all correct. The function e^(iφ) is the unit circle starting from (1,0) and running CCW with period 2π. So iπ/2 is the power of e that maps to the point (0,1).

Multiple-host SCSI busses are only supported when all devices have a feature called "contingent allegiance." The tape drive is unlikely to.

Sorry, I misread that you had connected both computers to the same SCSI chain.
It seems like the CP150 is not SCSI2 compliant (incorrect LUN handling).

PACE, JBC, Weller, and Ersa make such stations, and as SAQ said, they are expensive. There are Chinese knock-offs from Aoyue that cost much less.
Quality control can be an issue for Chinese tools, but there are some that do carry warranties and support, like the CSI labeled ones.

Shoddy and counterfeit goods aren't a joke, they are dangerous to your health and safety.
Chinese-designed electronics are the latest in a string of tragedies caused by feckless oversight and corrupt bureaucracies. Or I suppose you could ask the people most affected, the parents in China who will risk jail to acquire baby formula that was made somewhere else.
