I had this board working about a year ago. Tried to run it yesterday and it would not boot. MAME for ref: https://github.com/mamedev/mame/blob/master/src/mame/sega/segaybd.cpp I looks like First MC68k CPU IC12 (315-5314 on MAME ascii art schematic), is stuck in a boot loop, 2 other MC68ks are...

Free for anyone who wants it and pays shipping from FL 32218. These are 2 client terminals. The system usualy has a hub and 4 terminals. So you must already have a hub or willing to search for it on YAJ/elsewhere. I personally saw this thing connected to Dissidia FF cabinets. If no one...

Considering selling this cabinet to make more space for new projects. Projection screen was refitted with DLP projector. See more details on the conversion here: https://www.arcade-projects.com/threads/sega-harley-davidson-la-riders-crt-projection-tv-to-dlp-conversion.24549/#post-367143 Very...

Located Florida 32218, pickup only. Has some minor discoloration at the bottom left of the screen (not in the photo), should be degaussed with a coil. My old project, done for myself, but didn't use it a single time in 2 years, so may be it needs a new loving home. Comes with a TV stand, if...

I really want to start picking up all those free curbside projection TVs locally, check them up, then remove and store the projection unit for future use. Like for restoring SEGA cabinets. While these things still popup here time to time. Space permitting, should be able to hoard ~20 units...

Finally ran across CRT rear projection TV with nice tubes. Modded it with RGB inputs, in case I would want to fit into some SEGA game. For now would be my primary jammaTV.

I have "upgraded" CRT projection to DLP. Everything was working when removed, just the tubes were old, dim and with some burnin. If anyone needs any parts from this to fix their own SEGA projector (not sure if it is Toshiba or Mitsubishi) - it is free, you just pay shipping from 32218. I would...

First of all I would have prefered to keep CRT, if that was possible at all. I even got huge 4:3 SONY CRT projection TV as a donor, but realized it also is not bright, as it should be, anymore. I guess with last CRT rear projectors made decades ago it is not that easy to run across one with...

21" CRT Original chassis had flyback shorted. Had the chassis replaced with a cheap chineese one. Geomery looks perfect, but the colors are completly off. Degauss does nothing. I guess the tube is way over it's usefull life? Or I'm missing smth?

No, this is not an overgrown kiddie-ride. This is (I believe) rare full motion cabinet with Cruis'n USA game. It has standard CUSA pcb, which supports motion, if correct DIP is ON and special motion handling extra boards are connected, which it has plenty. This cab has some problems with PCB...

Cruis'n USA neon topper (2 seater top marque) Cruis'n USA deluxe (motion) manuals (scans ok too!) Cruis'n USA misc parts: motor control PCBs, decal stickers, etc.

I would be posting some pictures of my current restoration project. SEGA G-Loc Deluxe flight simulator - R360's smaller brother. Got this machine with completly dead lower part, looks like sometime ago it was stored outside (rust and corrosion) and it was home for a rat family too (major parts...

I wonder if Sanwa OSBN-24 (screw in) buttons thread pitch was changed one day? Red button you see here (picture from eBay) on the throttle lever is OSBN-24, with Sanwa marks, etc. But... it has smaller thread pitch, so newer OSBN-24 won't fit the joystick. I wonder if it was some custom order...

So one of SEGA Lindbergh monitors, I have in the arcade, recently died. Problem was in the backlight driver, that would go off 10-20 seconds after beeing powered on. This seemed beoynd reasonable repair effort (and origianl monitor is crap anyway with heavily worn screen). So I have took the...

Looking for 1 or 2 original cabinets in Europe. If you know where I should look for them - let me know.

I bet this topic was raised here few times before, but I wasn't able to find it with search. Is there a list of compatible memory chips for the DIMMs? From what I see - some work, some don't. Someone already tried compiling a list? I've got some Infineon (HYB39S256800DT) based mem (512Mb total...

Good day, masters! I have recently aquired 2 nice Naomi Universal Cabs and one of them has weird monitor problems. The picture is compressed when it is just powered on, but after a few minutes, when it warms up - it becomes so wide and tall that it does not fit the screen. I have tried front...
