shardian:
This has already been mentioned, but I'll reiterate it: Keep the Jamma and get a JPAC.
The JPAC serves a few purposes that make it valuable to a jamma cabinet. First, it is your controls interface. It plugs into the keyboard port of your computer. It has extra places for any buttons beyond standard jamma (6 button fighter layouts). It has a signal booster for the arcade monitor, which is necessary for some monitors to get a bright picture without cranking brightness pot on chassis. It also has a neat circuit that blocks all bad monitor frequencies from reaching and damaging the arcade monitor.

The only other thing you really have to do is pick a way to send a 15khz signal to the arcade monitor. This can be done by using an ArcadeVGA card, using soft15khz and an applicable old or new standard video card, or by using and configuring a DOS setup in 15khz output mode.

that would ofcoarce be THE way to go but i'm a litlle 'afraid' (not the word i was looking for :)) and that is because:

1) there is a lot more that can get broken, transformers, isolation transformers and not to forget the monitor itself.

2) the monitor is working, be it that it is not using the entire screen, perhaps i can easely fix that with the horizontal adjustment coil but perhaps there's more to it, i lack money and knowledge :(

3) i'm no computer nOOb but all new to mame so if i want to have something working in a reasonable time it will save me a lot of hassle, later on, when i'm more secure with the stuff i can allways go the route u discribe...

nofi meant ofcoarse and tnx for your input but this is how i see it at this moment in time, perhaps i need more persuading  :angel:

ok, i'll agree, i'm taking things a litlle slow, a well :)

i thought i'd try and make a sort of test setup first so made good use of the topfighter, i hacked a microsoft sidewinder in the thing whitch was a breeze realy (if only i'd had a look first.

circeled around are some nice point to solder to so i wondered, would they...



well, in fact they did and i figured that would make soldering a peace of cake so started messuring all the islands and drw them to paper.
i used an old floppy cable for easy counting, 15 wires in total and starting with red = ground...



only to find out that on the other side of the sidewinder....all soldering points where labeled, doh  : :angel:  :applaud:

anyway, that made life a lot easier still and all i can say, it works as a sharm if only it wasn't for the topfighter build in joystick, it just doesn't feel 'right'
example, when i have to enter my name for high score it seems almost impossible to get it mooving one caracter at a time, not very precise some how but still, this is only for testing purposses.

origignal inside of tf, made everything so that it will be real easy to return to stock if needed, no pic of the thing build in tho  :banghead:



what more did i do, got me a pretty descent (complete) mame setup only to find out my comp isn't doing very well on it, it's a 900 mhz celeron and i hoped it would be ok but well, it isn't, even when i try mame 0.59 it somehow won't cope with even asteroids or something alike, however, the games mentioned above play fine :)

things i encountered and don't get (yet)

put mame32 in my startup folder and when it autostarts on bootup it won't find my roms, flyers and the like (?)

thought i'd be able to play more games given computer specs;
(cel 900, 450 mb mem, gf 4 mx 32mb)

8 way joystick realy sucks at playing 4 way games  ;D

it's realy fun to solder and hack away to find that....it works!

and;

i still have lots to learn  :notworthy:
