PE+ CRT to LCD conversion

[knagl]

nousmeme-

Welcome to NewLifeGames!

Yes, we are very interested!  Please post or send whatever you have as a number of us would like to convert our PE+ machines to LCD screens!

 

Thank you in advance!

Hi Guys,

We modified many PE+, two years ago and they still work great.

First of all, you need to modify the mainboard (see the attached file).

We have to use the converter ACV-011 from Weiya.com.tw (http://www.weiya.com.tw/products.asp?le=english&fid=111) the price was $48.00 in 2008
About the DIP SW, I will give you the configuration later.

We use also a LCD from them, the MT15T SERIES (http://www.weiya.com.tw/products_detail.asp?le=english&fid=55&pid=39&tCatName=15%20in.) the price was $205.00 in 2008.

Unfortunately, I forgot the name of the guy who posted that on the old NLG website and taught us how to modify the mainboard.
Once again, many thanks to him.

Should you require further information, please feel free to contact me.

Enjoy

Welcome to NLG nousmeme

There are definitely a lot of members here who will benefit from an LCD conversion solution for the PE+.

P.S. I do seen to vaguely recall the information in your PDF document. At least the pictures look familiar.

Was there any modifications done the the Wei-Ya LCD monitor?
It looks like the modifications were done to the PE+ MPU only?
If not, then that means I can use just about any regular desktop PC computer LCD screen?

I will try modifying / soldering a couple of caprom chips in the morning if I can find an extra one laying around.

Great stuff, thank you (and K+) for posting it.   

A few of us have the Gonbes 8220 converter, which was made after the ACV-011 -- I think that it might work too, but we'll have to find out.

Would you be able to spell out to us how you have the video connected from the PE+ to the ACV-011, and what DIP switch settings you use on there?  Thank you in advance!




Mark (Bunker)-

I would *think* so -- that converter board that he posted should be able to output to a standard VGA monitor (CRT or LCD).

I'm putting you in charge of figuring out how to make this mod work on the machine side (rather than the board), so that I can do the mod once on my machine and be able to swap boards (I have different games on different boards so I'm not always moving chips around).

Oh yeah...making me the test pilot again... 
As if I didn't lose enough gray hairs last time we screwed around with this thing....

See, I'm trying to help -- by losing the gray hairs, you'll look younger!

(Unless the gray is all that's left!)

   HELLO GUYS
this sound wonderfull.unfortunately i cannot see the attachments mentioned
First of all, you need to modify the mainboard (see the attached file).
seems to me that an ordinary desktop monitor will...........the major question is=what did you exactly do to the
mpu board(2008 is not so far out of mind sir!!!!!!!!! PLEASE HELP US)

Good to see another AfRiCaN Join us WEL COME BAK

After analyzing the info presented, it seems it would be a lot easier to just replace the original chip (74HC574) with a 74HC564.  It is a pin compatible chip with a built in inverter.  It should mount in the same hole and be low profile.

Do you see the line below his post (Reply #76) with the attachment?  Look at where the green arrow is:



If not, this should be a direct link to it.

Ooh, that sounds even better.    Got one of those laying around?

Also, nousmeme, can you share with us how you have the sync hooked up to your CGA > VGA converter card, please?  Thank you in advance!

Sorry I couldn't find any.  They run about a buck a piece.  If you order any get the 20-pin DIP version.

Here is an eBay listing (with the wrong picture, $5.95 shipping)
http://cgi.ebay.com/IC-74HC564N-20-PIN-DIP-74HC564AN-74HC564-/390063508282?pt=LH_DefaultDomain_0&hash=item5ad198cb3a

Or you can get new from Mouser ($6.95 shipping):

I'll take 2 or 3 if you end up ordering

You will take 3, as I just ordered 6 of them -- 3 for you, 3 for me. 

[stayouttadabunker]

I got 3 as well...
Thanks for the chip info Stoli !

Now, I wonder how he hooked up the sync to the CGA>VGA board?

 HELLO TEAM MEMBERS

  has anyone tried to modify the IGT PE + MPU as nouseme had illustrated on the attachment:i have done exactly the same

i.e i married 74LS540 TO 74LS574,SOLDERER a twenty pin socket as directed,,,,i tested using an Ordinary TFT monitor and i Swear am almost there!!!!!

There is video on the upper half of the screen,color ockey,three cards on the left side of the screen and two cards on the right side...i pre suppose the issue
is video frequency.am STUCK.
LET anyone with an idea help me please,,,can send the photos if need be to anyone interested.Let also NOUSEME SAY SOMETHING now===we are heading to
the right place.

The instructions he posted will ONLY fix the inverted video colors.  The issue you are having is with the RGB frequency.  Unless you have an older monitor that supports 15khz, you will not get a clean signal.  That is why you must use a RGB to VGA signal converter from 15khz to 31khz so your newer monitor can accept the signal.

A couple members on this discussion have such a converter board, but do not know how to hook it up properly to the machine (especially the Sync portion).

[dougskenya]

thanks stoli.....we are all sailing in the same boat,,,,,,,i will try to work on the mpu board video frequency oscillator and
see whether its possible to double up the FREQ from 15khz to 30KHZ AND ABOVE..I BELIEVE there is a way.

thanks

[jay]

I like the way this boat is sailing....    would love to do this with out having to add in a video convertor..... keep up the good work and postings.

[knagl]

About the DIP SW, I will give you the configuration later.

Hopefully you'll re-visit this topic and let us know what you have your dip switches set at, and more importantly, how you have the wires for the monitor hooked up to the CGA -> VGA converter.  We need to know how the sync wires attach to that unit.  Thank you!

Hi everyone, this is my first post on this forum.

Like all of you, I have been trying to get my IGT video poker to work with an LCD (since the monitor up and died)
Well I am happy to report I got it to work!!!  Its onlt a rough bench test but it is working!!!
I know the big question is how did you do it?

We all know the video is inverted, so I found this:  http://www.mikesarcade.com/cgi-bin/store.pl?sku=NININVAMP
Its ment for Nintendo arcade boards since they also did inverted video.
Then I needed to fix the sync since it also is inverted, and I found this:  http://www.twobits.com/RGB/sync.html
and of course I needed an GBS-8220 CGA to VGA converter.
OK, now to hook it all together:
The red,green.& blue go to the video inverter board; the Horizonal & Vertical I tied together and ran thru the 7404;
the output from the 7404 goes to the video inverter board (it expect normal sync not inverted sync. Ironic huh);
Then the output from the video inverter board goes to the VGA converter.
And what do you know I almost had a perfect picture; I ended up adjusting (on the VGA converter) the clamp st=100 and the clamp sp=00.
Now I have a perfect piture, with the exeption on a little rolling from some interferance but seeing how I have wires all over the place it's expected.
Next I have to clean everything up with short wires and perf-board.

I really like the fix that nousmeme brought up for the colors, I may try that to compare results.

Welcome to NLG Big_D    and  for your first post. 
Hopefully your information will help the members who have been trying to get this to work for quite some time.

Hello Big D

Thats a great first post - Welcome to NLG and K+ for that info. Now that we know what setup works we can test the on board colour inverting mod and possibly also do a on board mod for the synch.

Still trying to source on of those VGA converters here in South Africa with no luck. Hopefully some of the othere members that have these already can hook theirs up and get it working..

Regards
Ian

[stayouttadabunker]

That's pretty awesome work Big_D !  
When you get a chance, you think you could make up
a diagram of how this is all hooked up?
It's been so long since I've worked on
it that I've forgotten how...lol

It would be pretty neat if you could show us a short
video clip or photo of the LCD powered up and running...

[dougskenya]

hae to all,,,
Congratulation to big-D FOR getting things done..this is all what we wanted..
Mine i got halfway in that i was able to get a good signal onto the LCD using the inversion style
NOUSEME had posted,,remember the u45 modification(inter marry 74HC540 WITH 74HC574) [/color]
but my video was half the screen,I AM BACK TO BOOKS NOW for more research,Is there anyone
with an idea as to how much it WOULD cost to get the original LCD CONVERSION kit from CERONIXS
right away/does it require any board modification/,]we might be spending more than what we can spend
when buying...what is the ease of getting the inversion cards-would like ten pieces if proven working please.
It would be pretty good if Big d posted some diagrams,,won't mind sketches or well enough a video clip.
i can post the photos of what i managed incase there is anyone interested,
