Hi,
Thanks to the generous loan of three big binders full of RT-11 v2 manuals,
I now have 20 megs of tiff images that might be of interest to others as
well. Three questions:
1) Is anyone aware of the current copyright status of these documents? Can
I give copies of such old manuals (1976) without worrying about possible
legal implications?
2) Depending on a favorable reply to question #1, would it benefit anyone
to have these available on-line? I currently have them broken
into chapters, anywhere from 600k to 4megs each (8.5"x11"@300dpi, BW)
3) If we got this far and they're going to be available over the internet,
does anyone have any requests to make specific formats available? I could
also make PDF and PostScript versions, or even make a wild attempt at
OCRing them (thought that would destroy tables/graphics)...

Sounds a bit like a Digital Vaxstation monitor cable. Does it have a part
no on it and/or a |d|i|g|i|t|a|l| logo?

I think the postage to Oz might be prohibitive, or I would.

Just to help anyone who's interested, it seems this A500 is in Adelaide
(pasteur.dialix.com.au is Dialix's Adelaide server).

Hi. It occurred to me to wonder if anyone has the 32bit Data General machine
that was backward compatible with the Nova, and subject of the book "Soul of
the New Machine". The project codename was Eagle, but I don't recall what
the machine was called when it was actually produced.
Heh. Serious collectable would be Gallifrey Eagle or one of the other 3
prototype machines. :)

I think that the ads are fantastic. I was about 13 in 1980, and I
remember going to the public library to read these mags. So, when I see
these ads I sort of have Deja Vu. If you look at the Bytes from 1978 through
1983, you can see the change in focus among the hardware platforms. It's
sort of like watching a flower bloom in slow motion.

The Northstar disk system was quite an item in its day, when it came out it was the lowest price floppy disk system on the market, by about half (it was under $500, and most other SINGLE drive systems were $1,000). That's because it was the FIRST commercially available system to use a 5.25" drive rather than an 8" drive. The drive was the Shugart SA-400, I believe (could have the number wrong), a full-size 5.25" drive. As used by Northstar, it was a 35 track drive with ten sectors per track (hard sectored), 256 bytes per sector, I think, total capacity as formatted was 80k or so (with some reserved area) (single sided, single density, of course).
The controller was dumb, mostly just gates controlled by software. To step the drive, the software wrote alternating, and properly timed, "1's" and "0's" to a port or an address (my recollection is that the controller was memory mapped). All of the work was done at a very low level in the operating system, which was also dumb, it only supported contiguous files and you had to "compact" the disk whenever holes were created by deleting a file.
Many of us made our first move from paper or (audio) magnetic tape to disk with this system, and crude as the system was, it was a HUGE advance at the time.
And a small New York city software firm, Lifeboat associates, became quite prominent in part because they managed to put CP/M on the Northstar system, a major feat at the time as CP/M had been pretty much exclusively set up for standard 8" SSSD drives (in fact, in versions 1.3 and to a lesser extent 1.4, it was hard coded this way in the BDOS, but in version 2.2 it became table driven so that other formats were more easily accommodated). The two principles in Lifeboat I knew quite well, Tony Gold, who was mostly a promoter, sales type and businessman, and I can't remember the name of the primary programmer who did most of the actual software development work, but at the time I knew him quite well and worked closely with him on porting CP/M to the Heathkit products. I will remember his name shortly after I "send" this message.
I still have source code (disassembled and commented) for the Northstar Disk operating system.

Okay, I have something that may interest you. One of Northstar's
first products, was a floppy disk drive, that could be used with
Altairs (among others). I have a pair of these 5.25" drives in an
aluminum/wooden cabinet.
There are inscriptions inside giving dates that it was built up,
upgraded, etc. I don't remember the exact dates, but it seems that
it was built in 1977.
I have reason to believe the drives are original; one still has the
N* nameplate attached thereto. The wooden top cover is in decent
shape, has a small bit of wood chipped from a front corner.
If this is interesting, I can get more particulars-- especially
corrolation of the dates with the actual Altair/Imsai/N* product
release timelines.

Just got an IMMACULATE Kaypro 2X machine, with all the original disks.
It doesn't have the keyboard cable though, but I imagine it will use the
same type as most terminal keyboards that have modular phone type
connectors? The port on back is clearly marked keyboard so no big deal
there.
Also on back is another modular, a little bigger but unmarked. Is this
possibly a modem or what else could it be?
Anyone have any manuals for the actual machine they want to sell, trade
or copy?

Yes, the board and the drive were released about the same time as their
z80 cpu. it was late '76.
The NS* horizon box with the wood cover and all (about 20" wide) was later
by nearly a year in mid'77 for shipments as kits.

About right.

Very common. Mine is near mint.

Sorry guys--
I'm sorry about all of the

I keep forgetting to watch those %$#^*&$*$#^ addresses!
Damn.
