Training cats is actually rather easy. It's commonly thought to be
difficult or impossible because most people try to train them using
the same methods they use to train dogs...which fail miserably.

It is WONDERFUL STUFF. Really incredible stuff. See

I can effectively "tune it out" and ignore it when I'm around it,
which I consider myself lucky to be able to to...but I don't like when
people I care about are smoking, because I know people who have been
killed by it.

There's gotta be something that can be done with that. ;)

<sigh> I'm not surprised, I've not had a chance to see what kinds of PDP-10
and PDP-11 stuff can be dug up. Hmm, for that matter, it might be time to
check out comp.sys.harris, and a couple others...

Hope you make it to Vegas! BTW what level are you? I shot for a few years
but never made it beyond a 4. No problem making the shots but post-shot
cue ball positioning hung me up.

Hmm, I have a kitty who spends some time in the computer
room...there's one particular machine in there that moves a LOT of air
and needs its filters cleaned frequently, but aside from that I've had
no issues with kitty fur.
And even if that weren't the case...my cat is one of the best friends
I've ever had, so if letting her go where she wants means some extra
filter cleaning for me, then so be it!

Sounds good -- and thanks for all the help on this box. I just got my
Z-100 up and dual-booting CP/M-86 and ZDOS, so the H89 is now at the top of
my Unfinished Projects List.

Easy to find, NEVER cheap. ;) I used to sell them for $5 to $10, then a
local Sun guy found out I had some and he bought them all.
Me too on the optical meese. I bought a CHEAP Inland brand for $8.99 at
MicroCenter, and its almost weird at first using it because it NEVER skips,
sticks,etc. and my brain isn't used to that. The scroll wheel spoils you
real fast too. My finger is already "looking" for it on lesser mice.
My understanding is that the new optical mice compare the surface image to
detect movement. Fancy stuff, but isn't the interface to the PC still the
same?

Would 200MHz be fast enough ? A lot of the Xilinx fpga's offer 5ns pin to pin
delay. I'd be interested in finding out about the 11/40 architecture - was it
a
bit-sliced design, how deep was the pipeline etc.?
I'm going to have a go at an HP21XX machine of some description next year.
It's just going to emulate some of the HP custom processors and speed isn't
going to be an issue. BTW the HP2116 Cordic Co-processor ran with a cycle
time of 200ns - not exactly fast - add/sub 50-100us mpy/div 100-150us. Yawn.

Does anyone know where I might find prints for a PDP-11/70? Like complete
prints? I was intrigued as I studied my own 11/70 with the possibility of
implementing an 11/70 in modern high-speed discrete logic.

Today I spent 8 hours moving stuff from one smaller storage unit to a
much larger one and found goodies I long forgot about. I have not seen
the back off this storage unit for almost 3 years. Here's a list of some
items;
1. PET 2001 series 2001-8 in good shape, will take home and test it.
2. CBM 2001 series 8 machine has been modified with new keyboard in
place of tape unit and smaller keys.
3. Commodore model C128D in great shape.
4. TRS80 model 1
5. PolyMorphic System 8813 model 8813/1 with wooden case.
6. CPT disk unit 8 ID# 931203
7. ADDS Ultimate model 25
8. SOROC model IQ120
9. Franklin PC8000 in great shape
There were a lot more plus I still have not finished moving items yet.
If I was not moving I would get me a heater and play also.
Perhaps slightly off-topic (other than being a resonably old part), but
would anyone around here have a datasheet (or, at least, a pin-out) for an
HP HDSP-2490? This is an odd, 4-digit, 5x7 led matrix display. It's in a
28-pin dip, and looks to have some intellegence built in.
The answer from HP (nee Agilent) is "long since obsolete, we know nothing".
Thanks...

You do know about Mentec's new-technology pdp11 processors, right?

Coupled with a meager $30k yearly as a sysadmin running an IIS

I found out about Richard Feynman's propensity
to yell out "42" as the answer to anything andf
everything from one of Douglas Hofstadter's books;
probably not G.E.B., but likely his duet with
Daniel Dennet, "Mind's I".
It *may*, tho, have been in "Metamagical Themas",
the compilation of his columns from SciAm.
In a very depressing time, dealing with a very, very
depressing subject, Richard Feynman provided me with
the greatest sense of glee I can recall. While George
Meany (or whomever the shirt was who was heading the
Challenger Disaster Panel) was going through the motions,
I was carefully watching an otherwise bored Feynman
start to play with the sample of rubber from the o-ring
seals. I saw him look at his glass of icewater, and
before I could form the though "stick it in the ice-
water" he was doing it, and then immediately started
to check his watch.
After a while, he raised his hand or interrupted,
can't quite recall which, and declared he knew what
had caused the disaster.
I'd give up all of Congress for one Richard Feynman.

Depends on the group, I think... I found that comp.sys.cdc
goes back to February 1989, just a bit before CDC killed
off ETA...
