the EADS (= european arcade distribution system) came into play again today. i was on a mission to mainz again to pick up some stuff personally delivered by the TATS (= transatlantic arcade transport system), amongst others a huge pile of manuals for various forum members and myself. a couple of weeks ago i had posed the question "arcade manuals anyone" (https://www.dragonslairfans.com/smfor/index.php?topic=3303.0)? my american arcade buddy pat went through his gigantic pile of boxes full of arcade manuals and came up with quite a few, although there's still a lot of stuff missing, but he's going to keep the list and work on it continuously. i'll be contacting the lucky guys shortly with a list of the manuals pat brought over for you. for now, here's a couple of photos :arrow:

i was also on a mission for mr lunar lander himself to collect a b/w television set he had bought on ebay. the seller wouldn't ship it to the netherlands, so andré asked me if i could pick it up for him. since the seller's location was just a mere 20 kilometers away from mainz i happily made the detour to pick it up. i have to admit, this tv is a thing of beauty. pics just don't do it justice :arrow:

all in all, it was a successful day for the EADS (in cooperation with the TATS)!!! :spaceace: :spaceace: :spaceace:

That is totally amazing what the users of this forum can accomplish! :spaceace:
Ahrem, i thought Lunar Lander was Vector?? why Raster Dré?? - something i miss??

Our transport system works like a charm with our selfless members. :-* :spaceace: :spaceace:
André, you should put that TV staright into your cab without removing the housing. ;D
Nevertheless, I also don't understand how will it work in a vector cab. ???
-
I think that a tube is a tube, its the chassis that makes the vectors right ?
-
had a chat with pat (note the rhyme) about that as well (man, he's just such a great guy to talk to), he said it should be doable, as long as the yoke fits a b/w tube fits. he told me much more about the conversion, but i've already forgotten half of it ... :P
-

I don´t know about that...
There´s some sort of screen in front of the glass inside the tube... dunno if a vector has this....
Though it´s not the first time i heard about this......

Allright, this is probably one of the most ringing misunderstandings about vector monitors.
Etienne is right. A tube is a tube. There is NOTHING (yes children, repeat after me, NOTHING) special about the TUBE in a vector monitor !
To understand WHY that is, you need to know what a picture tube does. Basically (for a BW tube) it does this:
1) the electron gun in the neck of the CRT shoots out a beam of electrons towards the screen
2) the electrons hit the phosphor on the screen and it lights up
That's it, that's all THE TUBE ITSELF does. Now if you would hook up a tube just like that,setting up HV to make the gun work and you would provide a constant voltage for the gun to show, you would of course only get one very bright spot in the center of the screen. In fact, that is what very often happens when vector monitors go defective, and this gives the well known burn spot in the middle if running too long.
But we can only get something meaningful from the electron gun when we make it move around the screen and to do that an electro-magnetic field is put around the neck which steers (or deflects) the electron beam. This field is controlled by the monitor electronics and makes it move in either a raster pattern (on a raster monitor) like this:
(http://www.diycalculator.com/imgs/console-03.gif)
OR it makes the beam move "like crazy all over the place" with a vector set-up.
The differences are in the yoke that is around the neck of the bare tube (remember that, these are two loose elements, although the yoke of course is glued to the CRT to keep the picture stable) and the electronics driving the monitor.
So, if I take the tube from a raster device (like a TV) and put it in a vector monitor yoke and electronics, it will simply work as a vector monitor.
There are NO differences in production of tubes !!!
BUT I hear you say, some others say you DO need a special tube for certain vector monitors !
The answer is yes and no. In color vectors like the Amplifone, tubes with a 110 degree angle are used. The angle of the tube means the angle at which the beam needs to be deflected to reach the screen in the furthest edges. What it boils down to is that the higher the angle, the flatter the CRT is, so a 90 degr. tube has the electron guns much "deeper" away from the front of the tube.
Now, 110 degr. tubes are simply more rare than the more regular 90 degree tubes. If you open an 80's TV, you will likely find a 90 degr. tube and not a 110 degr.
You can't use a 90 degree tube on an Amplifone because the yoke is meant for 110.
Again, NOTHING else is different about these 110 degr. tubes and there _are_ TV sets that have them.
But but....what about the higher resolution of the Amplifone monitor ?
Aha....that is an interesting question !
But simply answered: the dots of which the CRT's screen is built up are smaller on the med-res tubes used in Amplifone monitors compared to regular TV or monitor tubes. That's it. That gives it a (much) better picture compared to f.i. the WG6100.
This is also NOTHING special for "vectors" because a lot of later games also used med-res tubes in raster monitors, like 720 and Hard Drivin'.
So....if we go back to the BW tubes....the great thing about BW tubes is:
a) they ALL have the same pin-out
b) they do not need any convergence
So...I should be able to transplant the CRT from that TV into the vector chassis I got from Rémi and have a burn free picture :)
Now this is all just theory for me at the moment, but it will at least be a good practice before taking the dip in replacing a tube on a color vector monitor....
-
Thanks for that lengthy explanation, but i think it should be in the technical area in its own post and place a link in this thread to there.
(yes i know, i also go offtopic many time ;D )
Normally i dont care off topic , nut searching this back later will be a pain ;)
-
There´s some sort of screen in front of the glass inside the tube... dunno if a vector has this....
What you mean is a shadow mask. First thing to remember it that a BW CRT does not have a shadow mask because it doesn't need one.
Color CRTs need them to make it possible for the electron gun to hit the right colored dots (Red, Green or Blue) at the right spot.
(http://www.comp.dit.ie/dgordon/Research/Shadow_Masks/msk0001.jpg)
More about that on wikipedia: http://en.wikipedia.org/wiki/Shadow_mask
Again, since all tubes are basically the same shadow masks are in vector monitors as well as TVs and raster monitors.
There is one exception....an aperture grill (as used in Sony Trinitron tubes) can't be used in vector monitors because of the construction. It "expects" the beam to travel in horizontal lines only (when turned on) and not in every possible direction like what happens on vectors...
But I already put to much of-topic tech info here already :)

Coming back on that TV: man it really does look nice !!! It's going to hurt a bit to do that operation, but it is for a higher cause !

today the EADS worked its magic again!!!
when i received the delivery of the space wars from southern spain / the uk, i was also sent some zaccaria parts for bela which i stored for a while at my place. today, bela sent over a driver from hungary to pick up his stuff, but he also dropped off a big box mysteriously labeled "ULLY" 8)

inside, some nice toys which are going to keep me occupied for the rest of the holidays ... :P

thx a lot, bela!!! now i need to figure out who gets what. btw, EADS rocks big time!!! :spaceace: :spaceace: :spaceace:

Coo! :-* I'm Jealous now :P

Glad that EADS succeed again! ;)

thank YOU, bela!!! i will bring bruno's and andre's tron stuff to our BDB (= belgian distribution base) soon, thorsten will get his stuff (together with other parts) later this year!
-
YESSS!!! :spaceace: :spaceace: :spaceace:
-
Awesome box with even more awesome stuff inside ;D
Bela, where can I send the money??
And there's really no need to give me a "mystery item"....

And arrived yesterday in order. ;)

Thanks to all of you, EADS rules. :D

Love the pac zacc bezel !
Never saw it before, only a pic from the cabinet ....
-
Awesome stuff, Bela!! :) I really love these Zacc marquees!
Do you own any generic cab with LS-32, JLF, JLW or Happ-Sticks? I might throw a pair of glowing sticks towards Hungary ;)

I can make some scans and send them to you stitched together, lol! :D

Thanks Thorsten, I have no idea about these model numbers, a pic from your sticks would be great. ;)

from england via germany to hungary - thumbs up for the EADS!!!

Happy to see the parts arrived safely :)

Cool! EADS strikes again! ;D
