anyone have the dimensions for an upright asteroids cab? i cant seem to find anything here and jakobud doesnt list it. the main thing at the moment though is to get upright dimensions and control panel layout.thanks in advance!!

Funny, I was sure Jakobud had Asteroids plans. I don't know where else I would have seen them.

Asteroids does have a cocktail version, it uses the same PCB as the upright version but is wired slightly differently (when certain pins on the connector are closed the PCB knows to flip the screen, open one players controls and close the other players controls; thats why the PCB only has inputs for one player)

I've been waiting for an emulator that emulates cocktail Asteroids, but I don't think its ever going to happen

i know my version of asteroids didnt have a cocktail support...

If you have an actual asteroids pcb then yes, it supports cocktail. It depends on how you wire it. Read page 4 of this doc

Here's pics of the wirings schematics I took.

Right. So there's seperate grounds on the harness for Player1 and Player2.
How do you think this could be emulated in Mame? Should there be a seperate rom set or a fake dip-switch added?
Every few months I bug one of the Mame devs about adding cocktail support, and they show a little interest then give up. It'd be nice to see it happen some day.

Well, a fake dipswitch probably could be added, after all all you are fdoing is shorting pins 7 and 19 on the harness, IE put a switch on those pins

I'll email the mamedevs too.

cool. i was referring to the mame version. would be nice to able to play it properly on my cocktail cab one day!

so does anyone have the dimensions for the upright? jakobud definitely doesnt list it...

nobody?

danny_galaga · « **Reply #7 on:** August 01, 2005, 09:40:51 pm »

bump. just in case theres a new guy on here who just so happens to have the dimensions...

I asked Jakobud about this a while ago. He didn't have the dimensions at that time but thought he might be able to get them from a local machine.

Have you asked him, or just looked at his web site?

You still need dimensions? My cab:

Was a converted Asteroids cab and I'll measure it if you still need . . . ?

danny_galaga · « **Reply #13 on:** October 19, 2005, 06:54:21 am »

thanks for the replies guys! cheffo is onto it! so hopefully ill be able to start a new project this year (",)

Any dimensions yet?

CheffoJeffo · « **Reply #15 on:** February 09, 2006, 11:01:55 pm »

Odd ... I pulled out the MJ beside the Asteroids today and said to myself "hmmm ... I still owe Danny Galaga those Asteroids dimensions" ...

I'll try to get to it soon.

Cheers.

ok, well ascar9 came up with many of the dimensions of his cab. ive drawn them up so its easier to follow. the drawing was done in paint, so its not to scale! be warned. the dimensions are as close as i could get. obviously A, B, C, E, G, H i dont have clear measurements of. these could probably be extrapolated in a drawing program.

im amazed there arent full dimensions out there. this is quite a classic cab. that and space invaders. anyway, here is what i can contribute (with much help from ascar). cheffo, if you can, can you compare to yours to see how close they are? i noticed two different dimensions in two different flyers for instance so who knows how many marks of cab atari made...

edit: i also don't have a dimension for the radiused corners, and so they appear angular in the drawing. i would need to have a cab to hazard a guess. the easiest way to measure them would be to use a few objects (like coins, glass tumblers, aerosol cans, etc) of different diameters to see which most closely fits the actual radius...

Just bumping his back to the top to remind myself ... once I drop the kids off and clear the morning workload, I'll drag her out and fill in the measurements and get the radial nmbers.

My apologies for letting this one slide so long.

Cheers

and you STILL forgot, didn't you?

Yep .... $:-\$

OK ... here is what we have so far ...

A is 4.5"

B is 9.5"

C is 23"

D is 9.5", with the caveat that is measured on the side panel. If measured front-on, it is 8.5" (excluding marquee retainer) since the top and bottom of the marquee are each recessed by 0.5". You will notice that this doesn't jive with th existing measurements, so I remeasured using theoretical squared corners and I get 38.75 instead of 39.5 and 24.25 instead of 24 for the heights of floor to CP and CP to marquee.

E is 25.25"

With respect to F,G,H, what is the frame of reference for measuring ? There is the plexi bezel, which has a large, easy-to-measure viewable area and the inner folded cardboard bezel (shroud) that surrounds the screen and is tougher to measure.

On the other hand, if you are going to build using a standard black bezel and 19" monitor, you can simply center within the screen area as anything else would look odd.

What you may want to do is grab Zakk's Asteroids model and scale to a height of 72.5" as that is a prety solid measurement.
