Subject: One Battlemech - Can it do that ?
Date: 7 Sep 92 20:38:22 CST
Organization: Washington HS, Milwaukee, WI

This is for Battletech and the exact design of a 'mech 
that my friend built.

He took a Maurader (sp?), and started to convert it into
clan tech.  Simple eh?  What he did was put an aerospace 
engine into the mech plus the regular engine.  This is a 
100 ton mech.  This craft does not convert into a aerospace
fighter like a LAM, but rather he uses the engines to just 
hover about 6 levels high.  Using that he uses his jump
jets to jump around when not moving far, but when he decides
to really move, he says that he can move about 12 boards ( It
takes him a couple of boards (2-4) to turn around and then 
he would strafe (sp?) the mechs on my team.  Anyone within
the 3 hex region got hit with 54 points (total energy weapons)
plus whatever autocannons, or missles that he had only once.

At the time, we were playing a high powered game.  We were playing
with all Inner Sphere clan modified mechs.  My other two team-mates and
I were playing a 100 ton, a 65ton, and a 55 tonner.  Their team 
consisted of 3 100 ton mechs and a 5 ton hovercraft.  Six people
total were playing and four were just beginners.  I believe that my team
could have taken them, even though they had more weapons and 
armor.  The 55 ton mech pretty much took out a modified atlas by itself.
The 65 ton (modified Thunderbolt) that I piloted took two strafes 
and was still around until he fired his AC's and missles at me.  
The 100 ton took two and still had enough to spare except that you
could not hit the 100 tonner that was strafing.

My questions are as such:
1) Is such a thing possible?
2) Can something that big strafe?
3) How many heat sinks would that include?
4) How many people out there think that this is fair?
5) When attempting to attack it, must you include the
fact that it is 6 stories up, or consider it on the ground?

Please E-Mail, but I would REALLY like to know the
answers to my questions.

I'm not really sure I believed this when I saw it, so I read it again.

It's bad enough that photocopies of the manual are being passed around,
but since there is no other way to get any useful information, *and*
since it is not taking bread out of the copyright holder's mouth, I suppose
it can't be helped.  It is still technically wrong, tho.

On the other paw, offering to sell these same illegally copied manuals for
personal gain is reprehensible.  It is theft, pure and simple.

If anyone in this group wants to flame me for this, I will just withdraw
from this newsgroup permanently, and contribute no more goodies or
opinions.

If the author of the msg this is in reply to, decides to go ahead with this
plan, I will contact the authorities, and there is a large organization
that watches for just this sort of thing.

Getting donations to pay for copying costs incurred is one thing -- this
is something completely different.

(Assuming you are running X-windows)

I was able to load the damaged files using "xv".  I then re-saved
them as TIFF files to correct the errors.  (xv can also save in various
other formats (pick your favorite!) as well.)

I then ftp'd them to a mac and printed them out using Photoshop. 
(I couldn't get the sun, unix graphics tools, and HP printer to print them)

Unfortunately, pages 20 to 31-4 were too grainy to read the circuit
diagrams anyway.

     Hey!  I just got a Vectrex today!  Happy Happy Joy Joy!

     Now for my question:  I seem to remember that, while reading this group
some time ago, I came across a discussion of some simple hardware fix for the
awful humming sound that (some/most/all?) Vectrexes have.  Does anyone remember
this, and is it something simple enough that even a non electronically-inclined
person like myself could handle?  I wouldn't want to void the warranty by
opening the unit if I wasn't sure I could actually do some good in there. :)
Any information on this would be greatly appreciated.  I would really like to
have "clean" sound on my unit.
     (This would probably also be a good item for the FAQ.)
     Thanks!

Personally, I don't care what Myron decides to do with the manual.

Jeff, it's just as illegal to give away copies as it is to sell them.  It
weakens your argument to grudgingly allow one while forbidding the other.

And by the way, all the Vectrex binaries are available for downloading
from the archive.  This object code is copyrighted too, and copying it
is just as illegal as copying the manual, yet I don't hear anyone complaining
about that.

Yes on both counts.  It is so good I think it is a copy of the original.
I vaguely recall that I acquired the manual from Jeff Woolsey, who may
have been one of the original Vectrex designers/programmers.

I also have some other printed stuff I've acquired over the years from
reading this group and from here 'n there elsewhere.

Hyperchase is supposed to have one), and the instruction booklet?

  Spike (with voice!)

and any of the cartridges and accessories which have been mentioned on

I'll make everyone the same offer:  one nice readable photocopy of my

Well, sorry I've been so long posting about the subject.  Been real busy.
Also, I might not have been very clear about describing my thoughts.
This damn language barrier again!  (Maudite cochonnerie de merde!)
I've played around with my unit (The vectrex! :) last weekend and found:

1- The noise isn't digital in nature.  It closely follows the video.
2- It isn't a power supply problem.  Isolating the audio input of the
   amplifier from the sound circuit revealed no noise at all.
3- It's actually generated two ways.
3.1 : By induction; moving the audio cable around makes the noise less or
      more prominent.  It is at minimum when the cable is placed in its
      original manufactured groove.  Good design since that's farthest from
      the crt yoke.
3.2 : Grould impedance;  Although all supplies are clean the hum is still
      present in the modulated dc difference between the two boards.
4- Some pots on the digital board needed adjusting. (Lines didn't connect
   quite properly on image) (Not related to noise problem.)

Solution to noise problem: Rewired ground between digital and video board,
