10th of July 2005

OK, so following the road trip :



...the next step is -of course - to see it working, and far  better, playable  Exclamation  Smiley

Here's what happens when I power up the game :



The Dragon's Lair PCB led displays P :



Ok, the first thing to do is to get as many documentation as possible  :idea: One place to go for in-deep laser disc stuff : http://www.d-l-p.com

I get the service manual for the game, and for the Laser Disc player :



It's seems that the Philips 22VP932 LDP has a problem  :x



Check out the video of the LD  problem -> http://www.dragonslairfans.com/dlfix/laserdisc.AVI

The LD produce a repetitive noise... the "ON" button seems stuck... and I'm not able to eject the disc  confused



There's a procedure in the LD manual, but not really clear  confused  Thanks to Matteo ( Regular at D-L-P.com ) for the eject procedure confirmation   Tongue

So now, I can have -a least- a look at the laser disc itself :



...closer...



Thanks (again!!!) to Matteo, according the previous video of the problem, it can be an optic path problem.

Let's open the player to see if i can clean the mirrors and others optical parts :



I've used bomb air spray to remove dust from the LD player, and clean up with alcohol lens & mirrors... but the problem remains  confused

Check out the video of the optical lens  problem -> http://www.dragonslairfans.com/dlfix/opticaljump1.AVI


Check out the video of the optical lens  only -> http://www.dragonslairfans.com/dlfix/opticaljump2.AVI

Mhhh, it doesn't looks good at all ... It'll probably an hard fix...   :cry:

Ok, I have another laser disc player, a SONY LDP 3300P.

Let's test the laser disc itself :





The laser disc seems to have no problem ( I didn't check it to the end ) : crisp image, a no laser rot... at least a good new Smiley

There are few solutions to play Dragon's Lair inside the cabinet :

Use Daphne emulator -> It'll use my Sony LDP ( it's working, see Dragon's Lair -> Daphne Project link ) but it won't use the PAL PCB with score overlay  Smiley


Use a laser disc card converter, such the LaserAce or the Hi-Tech card but I'm not sure if it can works with the PAL version of the game...

Use the Matteo's EURO Dragon's Lair PC Conversion card, which it sounds the best option.

Full details here : http://www.d-l-p.com/tech/docs/eurodl.asp

In short, it'll use my real DL pcb to play the original game with an another LD player... So I'll keep the game overlay text   Cheesy  That's exactly what I want to...
To complete this interface, there's a custom board to build... Matteo explains it very well on the construction section... but I'm not fluent at all with electronic construction board... oops:  oppps  oppps

To continue...  roll eyes

11th of July :

I have all the parts needed to built the Matteo's "EURODL" cutom card interface :

- an IC MAX232 manufactured by Maxim
- five capacitors are 1 µF 16 V
- a red led with a 750 Ohm resistor
- a 5 wire cable (from PCB to EuroDL interface)
- a 5 wire cable (from EuroDL interface to PC serial port)
- a 6 pin male Molex connector (for connecting to EuroDL PCB)
- a 9 or 25 pin female connector (for connecting to PC serial port)
- a cable with a wire nipper at the end to get + 5 V from the EuroDL PCB
- a socket for the IC MAX232
- a small multihole PCB

Here's the parts to start :



Here the shematic of the inferface I have to built :



 oppps  I'm stuck  oppps  I'm not famliar with these shematics  oppps  I'm sure it won't be difficult, but I would like to have a non-electronic shematic, like ->  joint wire 1 with wire 2, etc ...  oppps

Here's my starting point :



Help needing now  confused  A more simple schematic pleeeaaassse  ( maybe a simple picture done with paint and all the parts wired together... )  oppps  ...

17th of july

My Dragon's Lair is now WORKING !!!

 Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy  Cheesy

I've finished to build the Matteo's EuroDL interface who allow the DL pcb  the using of a LDP Sony instead the old shit Philips 22VP932 LDP  roll eyes

Here's what I've done :

First step, prepare all the components...



... and start the job...



... this is the first time I'm doing this... I had to learn electronic basis  :-/

 oppps  Thanks to all people who help me to understand the EuroDL schema  Cheesy  ... and especially Liodel from France who draw for me the "SCHEMA for begineer" conversion  roll eyes



Ok, so let's continue the job...



... I do it very slow... please don't laugh  oppps  But I'm motivate  Twisted  Twisted  Twisted  Twisted



...further...



OK, it's done... 4 hours later ...let's plug everything !!!
On that picture, you can see the old LD Player... I'll remove it of course.



Oh yes, a view from the back too roll eyes



The EuroDL card is now plug on COM2



So, I power up the Sony LDP 3300, the EuroDL card is also pluged to the original Atari DL PCB, and the computer runs the prg to remap laser disc command to the Sony LDP.... and ... and...

IT'S RUNNING... ALIVE... !!! Thanks my god !!! ;-)



*** NOW WATCH THESE VIDEOS TO SEE ALL THE STUFF RUNNING ***

1- EURODLcard ... all the installation ... behind the scene :  http://www.dragonslairfans.com/dlcab/eurodl-demo.avi

2- Playing the game : http://www.dragonslairfans.com/dlcab/DLrunning1.avi

3- Playing the game... again  roll eyes  : http://www.dragonslairfans.com/dlcab/DLrunning2.avi


And for my pleasure, other pictures of the game... running  Twisted  Twisted  Twisted  













Next step... use a smaller computer, and arrange all the wires to be 'as clean as possible'... I admit it's a real mess with all the wires, but was only for the test... I see now that everything is working, so, I'll arrange all better... :-P

... stay tuned...  Tongue

21th of July

Got from www.arcaderenovations.com new Dragon's Lair control panel overlay & 2 new sideart  Tongue Also received a new Wico joystick  Smiley

The stuf, well packed :


The new CPO is wonderfull  Tongue  Same texture than the original one. But this is  the US CPO repro, and the joystick/buttons holes in the ATARI CPO version aren't exaclty in the same location, so... I'll see what I'll do, I mean get a new control panel undrilled, or build a new one ? ... Don't know know, but it won't be a problem  roll eyes


Have a look at the side arts :  very beautifull...


... of course, because it's under Bluth license :-)


All the stuff :


The WICO joytick :


Stay tuned...  roll eyes  Tongue  Tongue  Tongue

24th of july

As you seen previously, my EURODL custum board is working fine, but I build it in order to test it ASAP  roll eyes

25th of july

Now let's arrange the computer itself  confused  I don't want to put an entire computer just to control the eurodl interface, so I'll keep the strict minimum  :idea:

Here's the starting point :



Removing the motherboard...



... and keep only the necessary parts :



The parts :

- Cyrix 233mhz processor ( Pentium 1 generation )
- 32 mb ram
- 1 floppy 3 1/2
- Power supply
- ATrend motherboard
- 2 serial ports

I'm happy because this motherboard can boot without a VGA & Keyboard plugged  Cheesy  That's exactly what I need ... no useless stuff  inside the cab' roll eyes

fixing the floppy...



... all the parts are fixed and ready to go ;-)



Next step : cut a piece of wood to fix this ensemble, and found a good place for the computer power supply inside the cab  roll eyes

... so stay tuned...

29th of july

Let's continue the integration of the computer, who'll control the EuroDl interface.

Cut a piece of wood...



... to fix under the computer mobo, to avoid any bad electronic contact



Ok, so all the computer elements are now fixed on a same piece, I've to found a place for the power supply  roll eyes  
Eureka  :idea: Just under the backdoor, close to the cab' fan :



... I never tought I'll use that small IBM 233mhz cyrix processor one day  Cheesy



... and once again, a new "evolution" of my EuroDL interface... the cables between the Dragon's Lair PCB and the EuroDL was to short confused ... now fixed  : Cool



Intergation of the computer / EuroDL interface done  Cheesy

arrow One switch power up everything

The only switch ( the original switch on the back of the cab' ) power up the pc mobo, the Dragon's Lair pcb and the Sony laserdisc player  Tongue  Yeah BabY Yeah  Tongue





The EuroDL interface has a nice location now  Smiley



Stay tuned  Cool

29th of july (bis)

Got two more packages from US...  roll eyes



Hey nice, a 'new' book to add in my collection  Cheesy
 oppps with all these arcade game restoration in progress, I've no enough time to update the website  oppps



And the big box includes a new metal repro bezel, and a new repro plexi for the monitor.

Have a look at the bezel ... wich one is the new  roll eyes  Tongue



Have a look at the plexi monitor...



That pictures doesn't show you the problem about the old plexi, so let's have a look closer, with more light  :idea:



... scratch, cigarets burn...  Evil  ... so you understand why I need a new plexi monitor now  Shocked

... place new bezel and plexi...



...  shock  Opsss... the metal bezel seems to create a magnetic field  shock I'll investigate  confused



so I remove the metal bezel, and the picture is back to normal.



It starts to look very nice anyway Tongue



... I'll check why I got the magnetic field with the bezel monitor  confused  Maybe a ground problem  confused:

Stay tuned...

30th of july

It's time to fix the new repro control panel overlay  arrow

First, disassemble the control panel :



Another view of the originial Wico joystick :



The control panel is now out of the cab :



For infomation the Atari euro control panel is not exaclty the same than the US Cinematronic version. The two player buttons size are different, and the fixation for the control panel is different too.

Fixing the overlay is not so easy  confused  One mistake and the CPO is ruined  Evil  So before to start the operation, I've followed this great tutorial from the Sam's Dragon's Lair Projectwebsite here :  http://members.aol.com/severlander/dragons_lair_control_panel.html
Congrats for the tutorial  

Ok, so I'm starting to fix the 4 buttons, in order to have the overlay perfectly aligned, and with the help of my wife, I slowly fix the CPO down part  arrow



Then I've removed the buttons, and apply the up part   arrow  Et voilą Smiley



The CPO repro is made for US panel, so I've to cut a little bit the down part of it :



As you can see, I didn't remove the old original overlay, because the new repro overlay has holes drilled... and I prefere to see old CPO picture under the players buttons than a big black hole  Cool

Ok, I can now put a brand new Wico joystick  Smiley
Arghh, I haven't new screws for it yet roll eyes So I'll use the original one for the moment... a little bit dirty confused



The control panel is now in place  Smiley



Oppss  shock  Without any particular reason the tiny transparent film that protect the overlay picture start go off on a corner   shock



Ok, hopefully it didn't affect the graphic itselft and I've found a trick to mask it but I'll check with the CPO maker what happens on the CPO  confused

Anyway here's the control panel now :



Stay Tuned  Cool

31th of July

And here's side arts step  Smiley

Here's the 2 screws who are fixing the right part of the monitor.



Once again, thanks to my wife for her patience and her precious help  roll eyes

After cleaning both cab' side, my wife keep the sticker horizontal, while i'm pulling down the white paper ( the paper on the back of the sticker  oppps sorry for my poor english ) with my right hand, and apply the sticker with my left hand...



10 minutes later, it's done... we take time to do the best job possible  roll eyes  It's was the first time I'm applying a so big sticker  oppps



... and the greatest moment : removing the tiny upside sticker protection sheet...  roll eyes

Yeah baby Yeah... perfect... no air bubbles  Tongue
In my opinion, it's impossible to fix such side art alone... too risky ... don't try that alone !!!



Let's repeat the same operations for the other side... and voila :



Mores pictures...  Cool  Cool  Cool












Stay tuned...  Cool
