I am liquidating a shelf full of early 80's -era microcomputer parts
and not fully functioning computers. I have posted a web page containing
a complete list. http://degnanco.net/vintage/ If you are in the
Philadelphia area and want some or all will sell or trade for low
price.

I've heard John Oliger's stuff is quite good.
A friend had his TS-1000 all tricked out with a John
Oliger Disk Interface, Parallel Port, Color Graphics
Interface, Joystick Interface and more...
It cost more than an IBM XT did at that time.
We used to tease him about the "Tail Wagging the dog".
But, he was quite happy with it all.
When I worked for Zebra Systems, we were going to
carry John's stuff. We went out of the Timex Market
before that happened though.

Has anyone got a Documation M600 or M1000 that they'd like to sell? I
have a potential buyer.
Let me know...

Woz is a nice guy, but after his plane crash / amnesia there is
a lot that he doesn't remember. The story came from Al Alcorn
who had to fix the unshippable mess that Woz created.
I had wondered about the story about a year ago, while Al and I
were going through some of the old Atari documentation that he
still has, and I made a point of asking him EXACTLY why they
couldn't ship what Woz had built. The specific part of the circuit
is the on screen score circuit. There is a fairly complicated
glob of gates there around a seven segment decoder IC which
HP had reduced to a single IC. Woz had used that part in the proto
that he built. Atari had to replace it with conventional logic.
They knew EXACTLY what he had built, they just couldn't put it
into production using the parts they could buy.

Hi Mark,
I happen to have an August 1983 BYTE magazine in front of me, which
has an artical entitled "Comparing C Compilers for CP/M-86" in which
they use the Sieve as one of their main benchmarks. They are testing
Williams, Desmet, Lattice, Computer Innovations and Digital Research
tools.
The artical is fairly long - about 13 pages. If this is of interest
to you, I could scan it and put it somewhere where you can get it.
Btw, this particular issue (Aug 83) is entitled "The C Language",
and has a lot of good material in it:
Theres also a comparison of 5 CPM/80 compilers which also uses the
Sieve as one of the main benchmarks, There's alse a comparison of 9
PC/DOS compilers, but I don't think (from cursory re-read) that they
use the Sieve in that one.
On top of that, there's an artical by Steve Johnston and Brian Kernighan
describing a lot of the design philosophy and early experiences, a couple
of general "into to C" type articals, and artical on C in unix systems,
A C bibliography, an artical on C compatibility issues between Unix and
CP/M and a bunch more - really a good issue (which is why it's one of
the few I've kept).
Don't think I want to scan the whole thing (unless you want to wait a
*LONG* time) - but I will do what I can to get any parts you are
interested in to you.
Regards,

Need a value for a NEC 9801/VX desktop computer a Japanese model with manual
and 250 floppy diskette (all in Japanese). Also has keyboard and box with a
new harddrive in it. Any help would be great and thanks for your time.

Though it is true that Jef Raskin started the Macintosh project at Apple in 1979, his Macintosh was to be an 8-bit utilitarian machine. It would have had a bit-mapped screen, but no GUI or a mouse at all. Jef Raskin has always been very devout in user interface which promotes keeping your hands on the keyboard. His 1987 Canon Cat is more along the lines of what Raskin's Mac would have been.
Raskin simply gave Jobs an easy existing platform "vehicle" to take over, when Jobs was denied control of the much touted Lisa project. Raskin left Apple in 1982 after Jobs took over (but I think he still signed the Mac inside case - anyone?). Jobs wanted to out "Lisa" the Lisa project, and so the Macintosh quickly went from a $500 consumer computer, to $1000, to $1500 and finally to $1995 - that is before Sculley thought it should be $2500 minimally (thus was born Apple's outrageous profit margin on Macs).
Jobs certainly does deserve a huge amount of credit, however wrong he might have treated anyone, for his pure force of will in the creation of the Mac as we knew/know. He forced some design decisions which were wrong and Apple paid for (closed architecture, etc.), but he was 90% on overall (appliance design, one button mouse). His direction with Apple in the last 6 years has been mostly very good. Apple's stock is steadily rising now. The Mac consumer market remains at about 6% in the US, but their server (OS X) market is growing big-time. The Mac OS is excellent. I still love to set up my cube and run NeXTSTEP 3.3, which I now understand a lot better.
Here are some recent opinions of Jef Raskin's about the Mac: http://www.macminute.com/2004/02/11/jeffraskin

I can't find any reference to a Dumbkoff 1 orDumbkoff anything else
computer related, although I did find the word "Dumbkoff" used to mean
"idiot" or "someone stupid".
I did find reference to the Remington-Rand 256 bit tube. Check this out:
