ok thats seems crazy. so they do a lot different M1 versions by the way ....

I can only talk about mine Rom Version 755-16 2-21

look at following code:

Code: [Select]

00CA 04 D6     LODI R0 D6        Load 6 in Register0
00CC B0          WRTC R0         write this to the display (winmeter) : 100006
00CD F0          WRTD R0         write this to the Debuggerconsole
00CE 3F 04 F6 BSTA UN 04F6      jump to the memory test Subroutine
----------------------------------------------------------------------------------------------
00F6 ......
0567 77 02    PPSL              02 1D 01 FE 00 00 00 22 63 01 00 00 00 00 06 
056D DB 78    BIRR R3 0567      01 1D 01 FF 00 00 00 22 63 01 00 00 00 00 06 
0567 77 02    PPSL              01 1D 01 FF 00 00 00 22 63 01 00 00 00 00 06 
0569 8F FE 16 ADDA R3 1DFF * #  00 1D 01 FF 00 00 00 22 23 01 00 00 00 00 06 
056D DB 78    BIRR R3 0567      00 1D 01 00 00 00 00 22 23 01 00 00 00 00 06 
056F 75 09    CPSL              00 1D 01 00 00 00 00 22 22 01 00 00 00 00 06 
0579 FA 6C    BDRR R2 0567      00 1E 00 00 00 00 00 22 42 01 00 00 00 00 06 
057B 17       RETC UN           ; this returns from subroutine to the calling part from 00CE
------------------------------------------------------------------------------------
00D1 20       EORZ R0           ; Clear Reg0
00D2 CC 1E 2F STRA R0 1E2F      ;write 0 to 1e2f (ram)

This memorycheck goes from 0000-1dff all M1,m2,m3 and P1 but not the rams , the rams will be tested at 100002
Thats all at the moment I can see in my Debugger.

So if you look at the sequence:

04 D6 B0 XX 3F AA BB

then you look at the command to write 6 to the display and call romcheck.
xx something (F0 ... write to debugger)
AA 04
BB F6

AA BB is the adress to jump to the romcheck and 3F means JUMP to Subroutine

whenever you see this sequence you found the romcheck in your M1 rom
we change here 3F AA BB to C0,C0,C0
this means No Operation (NOP) if the microprocessor see this 3 Nops he does exactly Nothing ( so it will *NOT* check the ROMs)

Could somebody confirm my findings please ?

My machine is still not running. Proms are rebuilt and 100% working after I recode the Gal equations manually.
Still debugging the TTL stuff.. (very boring..)

ramegoom · « **Reply #42 on:** October 26, 2014, 01:46:57 PM »

Sent you a PM.

So its wintertime and I have more time to debug the summerproject again.
I forgot to check the Powersupply because i was naiv and think "when the MPU is booting.. power has to be ok" but this is unlogical, especially
with this grandfather of CPU technologies.

so I connect the scope on c9 (smoothing cap) on the e2000 MPU

C9 Capacitor in front of Power Regulator

Here I measure the voltage to the mpu board
so its 12 V dc with an 2 volt ripple overlayed (Sawtooth waveform)

AC Coupling shows the 2 Volt ripple on the supply.
I think its too much for a cpu System, what you think ?
has anybody same measurement on the E2000 MPU ?

Question 2:

what does it mean if half of the connector J2 is cut off (upper aera in the middle)
and for what is the greeen Dil 16 Connector (lower right corner)

So *please help my* (and others with similar problems with my experience)

cheers

dhellis · « **Reply #44 on:** January 22, 2015, 11:37:40 AM »

I checked my E2000 MPU board and found 0.818 volts of ripple @120 hz. 2 volts ripple is to much as that would
be almost 50% of the 5 volt supply.

The missing wires do not appear to be cut off just missing and this could be because your machine does not use
any of the bits on this particular IO port (input port 0)

The other socket is for other options such as a sound card.

antichrist · « **Reply #45 on:** January 22, 2015, 12:18:07 PM »

thank you Dan !
0.8v seems ok with the bridge diode forward voltage.
time to rip up the supply pcb.

cheers

Could you be so nice and send me a picture of a bally Soundcard please ?
if I had one could I plug it in and it playing melodies or do I need additional Eprom swap with sound progam inside ?

Do you know why I get this message when I click NLG File System?

dhellis · « **Reply #46 on:** January 22, 2015, 12:36:40 PM »

I will have to see if I have a picture of a sound card but someone on this forum must have one. I also don't
think you would be able to use if even if you had it because your game does not support it and you need a
P1 and P2 chip that would support it.

The message you are seeing stating that you are not allowed to view the download area is because
that board is reserved for members that have donated or are paying. I'm not certain if donations alone
will open up the access so perhaps one of the moderators can tell you for sure.

Here is what the sound system looks like:

GOS · « **Reply #48 on:** January 22, 2015, 04:12:29 PM »

sound is provided by the P1 only - P2 is not for sound. The P1 has to have the ES option.

Good info, thanks.

antichrist · « **Reply #50 on:** January 23, 2015, 06:54:32 AM »

wow thank you very much Ramegoom and Gos

So finally i measure the voltages :

ZC (zerodetect) goes from 0-12V that makes perfekt sense, cause MPU can detect Low voltage and 60Hz frequency (mains)

Next the UR voltage (unregulated)

The ripple 2V is really hard on top of the 12Volt approx.

The 5 Volt Testpoint inÂ´t better, here the ripple Voltage is 0.8V and thats not perfect too, expecially if you look at the waveform,
the voltage regulator isnÂ´t working correct (should be a line in theory and almost in reality)

finally a pticture of my supply pcb:

11700 uF is really a big can !

[blink]Are you measure the same like me on your pcb ?[/blink]
IÂ´ve got the feeling that the bridge recifier is damaged ...

Cheers

ramegoom · « **Reply #51 on:** January 23, 2015, 02:55:47 PM »

I have several of these machines, and the power supplies on many of them have given me all kinds of problems, but it seems mostly related to the solder joints on the pin connectors. These factory pc boards are single-sided, and are pretty unreliable because of that.

Although it's not too big of a deal to refurbish the original supplies, I found it was better to re-design the board, so I stepped up and replaced all of them on the machines I own. Also, the 2.2uF cap has been replaced with a higher value cap, bridge rec has been replaced with a larger, 25 amp part, and the big electrolytics have a higher temperature rating on the new design. Added an LED for good measure. Also, plated-thru holes were a big improvement to reliability.

Anyway, check the solder joints first, and check the full wave rectifier for leakage - or better yet, replace it. I believe it's an 8 amp part. Current rating doesn't really matter, they all run about the same temperature regardless of current rating, so use a good heatsink with silicone paste.

Old:

and new:

Ramegoom

You left out a couple of features of your board. First though not visible in the picture due the 5 volt regulator
heat sink is a small bridge rectifier that replaces then 4 single diodes. Should that part need replacing or if
the owner wishes he can use individual diode as you have already allowed for this. Next is that you have the
ability to use 2 large capacitors in parallel. 11,200 Mfd is somewhat hard to find but finding 2 6,000 Mfd is not
that difficult at all. Personally I like the flexibility of your design.

ramegoom · « **Reply #53 on:** January 23, 2015, 03:26:41 PM »

Ha! Yeah, you're right Dan. I couldn't decide on the diodes, DIP or individual, so I put them both on it.

And the big cap, yeah, they're not so popular these days, so two smaller ones will work just fine.

antichrist · « **Reply #54 on:** January 24, 2015, 12:47:32 PM »

BJUTIFUL

really nice work Ramegoom.
the pcb looks perfect.
My pcb has dual bridge recifier, one with the heatsink (you can use an NTE53000 bridge) for the main power supply of the Mpu and other pcbs.
and 4 diodes forming an discrete bridge rec. for the ZC function.

unfortunately my multimeter are diying so I canÂ´t ohm the diodes out. very sad.

I follow your hint and re- solder the Bridge and Connector. after that I put it back in the machine.

now I get the following after Switch on:

so I switch off and after 2 seconds , on again,

now:

wow ! the 100002 Error seems gone :-))

enough for today, I rip the pcb out of the machine and will check all components tomorrow , with another multimeter...
think I get RANDOM results here on the Winmeter. They make no sense to me (compared with the manual)

@GOS
What and where can I choose to have an "ES" Option in the P1 ROM (jumper? )

Cheers

GOS · « **Reply #55 on:** January 24, 2015, 12:54:22 PM »

the P1 program has the sound built in - what is the P1 number i can check and see if it has es. program 6 digit code written on the p1 label or do a test 6 and it will display on the win meter.

ramegoom · « **Reply #56 on:** January 26, 2015, 07:46:16 AM »

I have about 20 E-series machines, and I know one of these machines has the sound system. The P1 is 585490 on an E-2090 machine. There is no P2 chip, and the M1, M2 and M3 chip part numbers are -80, -47, and -133 respectively.

Since you're into disassembling the chip data, I can send the binary for you to dissect, maybe find the ES data and graft it into your current P1 program. This could be an interesting project...

GOS · « **Reply #57 on:** January 26, 2015, 07:58:48 AM »

the P1 you mention 585490 does not have sound - requires a P2 and uses reel strips 241-13,14,15

ramegoom · « **Reply #58 on:** January 26, 2015, 08:06:35 AM »

Thanks for the lookup, GOS. I got these machines from a defunct casino, after being in storage for 15 years, and it may have a mix-and-match set of PC boards in it. When I boot the machine up, I get the alarm for the first five seconds (door open alarm), but no error codes present and the game plays normally, along with the reel spin sound and the win sound when it pays. Once it's booted up, it plays normally as far as I can see.

Do you know what P2 chip should be in it to match the P1 585490?

I have dozens of P1 chips and several P2 chips, maybe 6 different ones used between the other machines. All these different machines follow some sort of pattern for the M chips - mostly the same between them - but once you get to the higher M3 part numbers, seems to have use of both P1 and P2 chips.

GOS · « **Reply #59 on:** January 26, 2015, 08:15:44 AM »

the M1 2 and 3 are reel spin and error handling - the higher numbers are only new versions replacing others - have nothing to do with P2 (these are for special options - progressives etc). if you post a list of the P1 I will tell you what strips they use and p2 etc. looks like a 701 p2 will work - 2401 too.
The M1 80 replaced the standard 46 for added security and eliminate 7X tilts M2 47 original - M3 133 eliminates 9X errors.
