Greetings folks;
Picked up an EMC2 Orion the other day. Well. Someone else picked it up for
me, I'm supposed to get it on Saturday... The generosity of others.
Anyone else have one of these? Anything I should know about them before I
power it up for the first time?
To be honest, I don't even know what kind of interface it uses... On the
upside it comes with the Service and Technical manuals, so I shouldn't be
at a loss for useful (I hope?) documentation.
My thanks for any info you chaps and ladies can provide;
JP
Hello, all:
Well, my Northstar is up and running but I want to replace the flaky floppy
drives with two working Tandon drives. I need the double-sided TM100-2A
version, commonly used in the PC/XT.
If anyone has these, please contact me off-list. Thanks a lot.

Not that it matters much, but I think it's due to the way pages are printed
and bundled together into sections (graphs?).
"Signatures" is the correct term for the bundle of pages and "Imposition" is
the way the pages are laid out on the sheet. I spent 10 years as a
printer/typesetter.
In imposition, if you wanted a page left blank, you just left it blank.
I think labeling "page left blank" deals more with the expectations of the
user or reader of the book than of the printing process involved.

Megan, in a recent post (and probably every other post, but I wasn't
looking) has included in her sig line the following text;
+--------------------------------+-------------------------------------+
| Megan Gentry, EMT/B, PP-ASEL | email: mbg at world.std.com |
| | |
| "this space | (s/ at /@/) |
| unavoidably left blank" | URL: http://world.std.com/~mbg/ |
| | "pdp-11 programmer - some assembler |
| (DEC '77-'98) | required." - mbg KB1FCA |
+--------------------------------+-------------------------------------+
Can anybody shed some light on the origin and use of the term "This space
intenionally left blank"?
regards
Doug Jackson

I have used others, may of been amp. The main problem is that when using
standard 40 pin connectors they are narrower so it is possible to misalign
when plugging in the cable. I have put a blob of glue on the ends of the
connector to take up some of the slop so I can't plug them in wrong. DEC
used a 44 pin connector for the discrete wire which doesn't seem to be common.

I have all the original documentation, including the assembly manual and schematics. My first question is; has Heath/Zenith released H89 docs to P.D.?

IIRC, on power-up, you only have about 4 options as to what keys you can press. Pressing "B" should respond with "oot" (to boot the machine). I don't remember what the other options were.
I also remember a space bar tapping ritual, to syncronize the serial comm between the two boards. Don't remember when that was applicable, though.

Many printing presses are large enough to print 4 or more pages at a time on
one sheet. Then the sheets are cut and folded into sections. This means the
number of pages printed and pages per sectio have to be a multiple of 4. So
one often ends up with a few blank pages at the end of each section. Nothing
that can be done about it without some heavy-duty computer page composition,
easier now, but not even remotely possible before 1970 or so.

Hi Steve
I also have a MDS-800 and a Series II. I've not powered
up any of it yet ( too many projects ). I have a pile
of software and a bunch of document that all need cataloging.
I also have a couple of UPP's.
In the hardware I have, I have a non-Intel Ice for a Z80
as well.
I used to work at Intel in the development systems division.
We had Series II's and 800's as lab machines. I was responsible
for system test of the UPP products. If I haven't lost it,
I should have a copy of a Fig-Forth that I put under ISIS.

I've a .tap file with an image of the micro 83 maintenance tape. I
tried writing the image to a real tape using vtserver, however,
vtserver appears to want to put the entire .tap image into one tape file
on the real tape. Is there a program out there that will do the correct
thing (boot blocks in file 0, data in file 1, etc, etc)?
I'm running RSTS/E 9.7 on the machine and can xfer the .tap file to the
-11 using kermit.
