Believe it or else, about three years ago I posted the following
to the old list. Thanks go to the retrobytes.org folks for
putting it into a webby archive that is searchable by Google.

On NCR gear? News to me, but what do I know?
Should you happen to run across NCR Tower serial ports on DA15
connectors, the adapter cable that brings this out to a male
DB25 connector looks like this.
Both hoods have the following molded into them:
One side:
TERMINAL
1308-C036-0152
The other side:
006-0089359
U.L. E40323
Ohming it out yields:
DA15 DB25
1 - frame ground
1 ------ 3
2 ------ 5
3,12 ------ 4
4 ------ 6,8
9 ------ 2
10 ------ 20
11 ------ 7
I used to use this cable to hook up an HP 700/22 to an NCR Tower's
console port. I can't remember whether I had it plugged into a
null-modem-like thing or just a gender bender at the 700/22 end,
but there must have been something there because both the cable and
the terminal have male connectors.
Hope this helps someone.

If you did, it would _crawl_. The CPU in the Palm is an enhanced 68000
processor running at a fairly low speed (16Mhz? 20Mhz?). I think it would
be cool, too, but intolerably slow.
Have you fired up any flavors of PDP UNIX on it?

Damn...if someone DOES port that to PalmOS, I'll go out and BUY one

I still think "Palm Pilot" sounds like a euphemism.

I had a NCR tower with the 15 pin ports and didn't have TOO much trouble
connecting a terminal. Basically, I was able to trace the leads back to the
drivers (1488 / 1489) and determine which pins were for output and which
were for input.
It's basic RS232 stuff except the pinouts are funky.

Here's a link:
http://www.spies.com/~aek/alto/index.html
On a page:
http://www.spies.com/~aek/orphanage.html
that links to the first, link, the author implies he's got a
work-in-progress emulator started. He has some docs also.
What I don't think exists anymore is a readable pack containing
Smalltalk-72, Smalltalk-74, or Smalltalk-76. Supposedly, Smalltalk-78
was implemented only on the portable Notetaker. Smalltalk-80 would
most likely have been implemented for the Alto, but by then, much
faster Xerox workstations were available, and people stuck on Altos
would have thought of themselves as second-class citizens.
Archives do exist of Smalltalk-80; however, they are largely
unavailable. Fortunately, Alan Kay, Dan Ingalls, and others
who created ST80 at PARC have duplicated the effort now that
they work for Disney. The revamped ST80 is called Squeak, and
you can download a version of Squeak for almost every platform.
For more information on Squeak, check out this link:

Correction: There is a small plate in the front (acessable with pack
removed) help in place with 1 small screw that you swing up in front of the
heads. There are also 2 or 3 screws that you install in the bottom of the
drive to lock the motor in place.

My friend has found a NCR Tower32 machine, seems to be
build around a motorola 68020 board with a vme bus, it
has a number of dsub 15pin ports on tha back, seems to be
somekind of terminal interface.
Does anyone have any infomation about such a machine ?

Today, an AS/400 system has been thrown in a dumpster
with a forklift. I can't possibly lift it out of
the dumpster, but, if anybody has any use for some of the
cards, I'll try to recover some of them.
Some of the numbers in the cards are
2615, 6112, 2626, 6140, 2619, 6501, 2592,
3119, 2700 (two), 2800 (two), 2639 (many).
The machine is located in the dumpster behind the
Hotel school. With a little luck, it might remain
there a couple of days, but the weather looks
menacing this afternoon. And I know some metal scrapers
tour the dumpsters regularly.

For what it's worth... I've driven a 3/4 ton pickup with an 11/34A, VAX
11/750, 11/84 (in dual wide cabinet), NCR Tower 32/600, Terak, 2 TU80's, and
a PDP-8/i in it.. theres a way to get odd looks...
