Namco Cyberlead LED Panel Experimentation and Documentation

I'm sure it does work with a Cyberlead display, at the end of the day the display itself is a normal DMD...
The Cyberlead setup consists of 3 parts though, the display, the control board, and the IO board and this thread is about undersanding how all 3 of those work.

Replacing the control board and the io board to attach a Pi directly to the DMD display is no different than removing a game PCB and replacing it with a Pi plugged directly into the CRT monitor and then saying you understand how the game works.
 
Bumping this thread as I couldn't find a list of Namco System 12 games supporting the DMD display, anyone cataloged this?

From what I remember from the PCB's I own, and need to re-test some;

Games displaying stuff on the DMD:
- Tekken 3
- Tekken Tag Tournament

Games NOT displaying anything specific and thus the display just goes through the standard routine like any other Jamma/JVS game:
- Paca Paca Passion
- Paca Paca Passion 2
- Paca Paca Passion Speciale

Games I'm not sure about anymore and will re-test:
- Ehrgeiz
- Soul Calibur (should work according to the YT video linked to below)

Also as a bonus I can confirm Namco System 256 (Tekken 5) does not do anything with the display.

Here are some videos I found online of the LED display for the specific games:

Doesn't Namco Museum and Mr. Driller support the LED display? Or did I imagine that in my head?

if this picture is to be believed

this picture from Highway Entertainment seems to imply that Smashcourt Pro Tournament on System 246 also supports it:

Yeah I need to pick up a Mr. Driller PCB at some point :)

Seems like the list is getting longer of supported games :D
 
if I recall someone on AO a while back claimed that Libero Grande worked as well.

I don't believe so, it requires JVS support and Namco Museum is on system ND which doesn't have JVS support.

Potential Candidates are System 12, and System 2x6,

less likely but still possible would be NAOMI (since Namco did release a number of games on it)
and System 10 as some games had an optional JVS daughter board so maybe some of those too
 
Hello,

Has anyone already made a list of the components on the Cyber Lead I/O board? If not, could someone take clear photos of the board, zoomed in on all the components (even in several pictures), so that I can identify all the components on the board, please?

Thank you.

if you're trying to make a reproduction it will be a real challenge as there is a custom chip along with some CPLDs
you can see in these images from this very thread:

c4fd1658-9faf-4830-8984-a5aabb7c2fc3-jpeg.18409


you can see the most notable chips:
IC4 - NKK N341256 - CMOS RAM
IC5 - ATMEL AT29C020 - CMOS FLASH ROM
IC6 - C77 - Custom/ASIC (CPU)
IC7 - EPSON SED1351F - LCD controller (not populated on some board)
IC8 - ??? - RAM? (not populated on some board)
IC9 - Altera EPM7064LC68-15 - CPLD

you'd have to fin another source for the C77 custom (if one even exists). we'd need to dump the Flash ROM, and then you'd have the challenge of dumping or reversing the CPLD
 
Actually, I would like very clear and well‑zoomed photos of all the components.


I noticed that the PCB on the LED DMD is exactly the same as the I/O board at the bottom of the screen, except that they are not populated in the same way.

So I would like to buy a LED DMD I/O board and populate it the same way as the lower I/O board, so I can see whether that turns the board into a “normal” I/O.


It would also allow me to repair my original one.

most likely has different code on the CPLD and Flash ROM between the two boards. chance are the CPLD label will tell you the code/revision flashed

Based on what I can see from the photos and so on... they have the same code; there’s just an extra Epson chip for the DMD LED—probably to control it—and it’s not present on the I/O. In my opinion, since it’s an FPGA, there must be logic gates that determine: if a certain component is present, then execute; otherwise, use the I/O. As far as I’m concerned, they’re the same.
 
worth experimenting with!

have you been able to find a source for the EPSOM chip?

The Epson chip is only on the DMD's I/O, so I'm going to remove it to really set it up as if it were the I/O.

Do you still have the I/O at home? Could you please take some detailed photos that I can zoom in on to identify the different transistors and resistors please ?
 
I have a few of these boards but they're all buried in storage, would take some time to get them out for photos.
