Found out the issue. I measured the V on CSync was around 1v however changing the Csync line (from to Dn to CN2 did the trick. Does that mean my device was expecting TTL level sync ?

I don't recommend using CN2 if you aren't 100% sure (check your monitor specs). Also, there's a 75R/TTL switch that affects CN5 and 8pin mini DIN outputs.

This is what I thought but even after changing the switch to TTL I still get 1v on SYNC line on MD8.

What's the monitor's input impedance and how do you measure the amplitude? There are monitors (but they're rare) that require TTL voltage levels, but have 75R input impedance. The HAS' "TTL" CSync is basically TTL amplitude and high impedance.

Sorry i dnt know that level of details but I am using a NEC 135LC CRT projector --> http://www.curtpalme.com/docs/NECXG852_1352_User.pdf

Currently I am first connecting my HAS to a Extron Rxi201 which has a small LCD screen which displays H and V Khz. WHen connecting the MN8 sync line it shows no signal and changing that to CN2 it shows the signal.

I own the same Extron and it worked the last time I checked. Are you 100% sure that you use the correct pin for CSync (CN5, pin #3)? I'll test it again when I find some time, but iirc the amplitude when connected to the Extron was like ~2.6Vp-p which is within its tolerance (2 to 5.5Vp-p, 510R input impedance).

yes I am 100% as I tried the Cysync line through both MD8 and Cn5 pint 3.

Plus one more thing I use Brooks retro board and has a DB15 out of it. When I connect it to HAS all the buttons are on "ON" state (tekken 3 players keeps on powering up which happens on pressing all 4 buttons). This stick works just fine on my consolized MVS board. However I have DB15 (no electronics) pad which works just fine on HAS so I am assuming this could be powering issue (powering the retro board) but again it works just fine on consolized MVS (weird aye ?)

Not necessarily a power issue (you can measure voltage). How exactly do you connect it, I thought this was a multi console joypad emulator thingy (which doesn't include the NeoGeo).

Also, when you say "all buttons", do you also mean up, down, left, right?

Lastly, how did you measure the CSync amplitude?

I have connected the DB15 connector (break-out connector) through the screw terminal points on retro board.

Only the buttons (excluding Up,down, left right , coin and start button)

I measured it but setting the voltmeter to V (connect the probs to ground and CSYNC line)

Ok, so you connected the retroboard button inputs directly to HAS' button inputs. There must be some conflict with the HAS' or retroboard microcontroller then (because it's not a proper way to connect signals). I suggest using a buffer or at least diodes.

A voltmeter isn't the right tool for this and that measurement means absolutely nothing. You need to use an oscilloscope.

Do you have 5v connected from your DB15 to the retro board?

Finally, it looks stunning in person! Total length - 69cm.

Bad news is that my cable supplier sent me only one set of cables instead of the full order (without my consent). Kind of shady given the fact I paid in advance and these cables were expensive (100% assembled in Europe). I just hope they send me the rest in the first week of January as promised :/

That looks fantastic @RGB! I'm curious why the CPS2 kick header is on the male side, wouldn't you expect it to be on the female side that attaches to a game PCB?

I assume that is because many people already have a HAS to CPS2 kick harness. I would prefer a HAS kick connecter input instead. But then people would needa different cable.

 

[RGB]

@kuze - when you use it with the HAS, you don't need the CPS2 kick header, because the HAS passess all 6 button signals via the JAMMA connector and you'll only need a standard HAS compatible kick harness for the other end of the extension harness.

If you use a different supergun that passes less than 6 button signals via the JAMMA connector, this is where the optional CPS2 kick header might come in handy.

Exactly. CPS2 kick harness is popular, doesn't matter which brand of supergun one owns. If I used a HAS style (6pin JST XH) input in the extension, then a non-standard kick harness between the supergun and the extension would be required.

Brilliant, thanks for the clarification! What's the expected price point for the extender?

Does the extension remove buttons 4-6 from the JAMMA extension? Our is that what the dip switches are for?

There's a DIP switch for that (you can cut off buttons 4-6).

I may have missed it but did you have a price point in mind for the extender? If only it had a black jamma edge connector
