Burgertime & Scramble Arcade PCB’s

Just my luck this weekend I stumbled across These 2 Arcade Boards of Games I used to play as a kid at the local arcade. Yea I am that Old.

These Will be Repaired and Refurbished and will assist in getting my arcade board repair section of the bench set up.

Burgertime: Burgertime Arcade Game Info. This came out of a Cocktail machine.

CPU Board

April 2023, In the midst of my Facebook Marketplace scrolling frenzy, my heart skipped a beat as I stumbled upon a rare find: an original Burgertime cocktail cabinet for sale locally. The adrenaline rush was palpable as I frantically clicked on the listing, unable to believe my luck. With bated breath, I quickly scanned through the details, verifying that it was indeed the authentic deal. Without hesitation, I reached out to the seller, eager to make this amazing opportunity mine. Could this really be happening? I thought to myself, excitement coursing through my veins.

The Seller responded later in the day, which felt like an eternity. After finally striking up a conversation, we were able to reach an agreement on purchasing just the cabinet and original controls. Knowing that these types of deals tend to go very quickly, I knew that it was now or never. Despite the late hour of almost midnight a kinda long drive and the minor setback of losing a headlight during the journey, I proceeded with the pickup and successfully retrieved the “Burgertime Cabinet” from the seller’s location about 45 min away.)

Coin Door/Mech and Counter 26,993 Whats that $6,733.25 LOL

After retrieving the “Burgertime” guts and harness from their storage area, I now have a safe place to store all of my Burger Time parts – conveniently in the cabinet. I will need to find the time to bolt them down and permanently fix them to the cabinet. But right now I know where they are at when ready off my shelf.

When I unloaded the Burgertime monitor back in October, I never really paid it much attention. However, as I recently took a closer look. I noticed some unsightly screen burn ohh well!! I examined the K4900 Chassis and noticed that it appeared to be original, with the neck board still sporting its silastic glue intact. This suggested that it had likely never been removed from the tube, which was a promising sign It’s not been hack on over the years.  While I may have a better tube that I can swap out to remedy the screen burn, First I am going to do a full service on the chassis to ensure optimal performance before placing the monitor back into the cabinet or doing a tube swap.
  
Upon closer examination, I have come to the realization that I am in possession of an untouched virgin K4900 monitor chassis. Noone has hacked on this Chassis so it being unaltered, It Will make it easier to service.

After a few days of searching, I finally located the message from the seller of the Burgertime guts in October. Once I found it, I wasted no time and immediately messaged him. To my delight, he confirmed that the cabinet is indeed the one from which the guts came out. This is excellent news! I Now have an all original Burgertime cocktail.

I’m getting ready to start the reassembly tonight. Specifically, I’ll be starting with the harnesses. Unfortunately, there’s no routing diagram to follow, so I’ll have to figure it out as I go. It’s not the most thrilling task, but I’m up for the challenge.

Need to find out ground strap Routing.

That’s It for the Night..  Ran out of Screws and Clips.

While back I was doing some in circuit ESR Testing for and Went for a cup of coffee returned to the project and Zap caps recharged the moment i hooded it up I knew I took out my lcr meter. The Imfomaus BK Precision 879B Err E02 Happened.  I did as quick Google Search and the EEVBlog as usual came up long with BK Precision Page saying check Fuse 200 Fuse 200 Was Good.. EEV Blog Post said Check th -5V Rail sure enough it was shorted.

BK Precision 879B Err E02
The Voltage Inverter U603 a TPS60400DBVT was the problem.

I orderd some then I got distracted with other jobs not nrequiring the LCR Meter and I misplaced them so had to order more thjis time i got right to it so i would not misplace the small pack again. so now it was time  Remove the TPS60400DBVT

Clean Up The Flux, and tin the small SOT23-5 pads of U603

Installed New TPS60400DBVT in U603 Chewcked the -5V TPO and checked good no short.

Install a fresh 9v and Power it on for a Function Check all Done. LCR Meter is Back to Working Order! Total time for fix about 10min waiting for parts 2 weeks.

Next weeks control boards that will be in will be a fast fix now the LCR is up and running will prob cut 3-4 days off my Mail In Repair Queue.

Tormach ECM1 V1.5 Control Board Repair

While Browsing the forums I frequent I  Seen Someone Post that they Burnt up their Tormach ECM1 V1.5 Milling Machine Control Board and Post was 8 Months Old.

The person posting hooked up the +24V Reverse Polarity Oops! Yep, He let the magic smoke out!  Sadly with modern electronics Tormach would only sell him a new ECM V1.5 a $625 board and not repair it.  Usual them with manufactures these days.

Since I have Repaired a half dozen or so Older Machine Control Boards PN:31045 / 301262 and more then a few dozen Tormach Leadshine Stepper Drives PN: 32000 etc. this is a perfect patient Board to explore.

I immediately messaged the poster and they responded a day or so later that they had already replaced it with another Tormcah ECM V1.5 board.

I asked if he still had his broken Tormach ECM1 V1.5 he said he did so I struck up a negotiations for the broken one.  We Came to an agreement and I sent him a USPS Label. With out delay he packaged it up and the board arrived a few days later.

People like me love saving tech form the land fill or scrap processor extending its useful life or putting it to use again elsewhere.

Tormach ECM V1.5 Board How it Arrived.

Immediately Under the Microscope it Goes. First check for physical damage!
Tormach ECM1V1.5 Control Board On the Bench.

First a Physical Inspection, Physical Damage Noted:
Missing a Relay (Not Reported), D22, D23 (1N4148WS-7-F SOD323) Blown Off Board (As Reported)

Second, Hook up Power 24V DC to the Siglent SPD-3303X PSU Not Even 1mA draw.

Third, Do Some Probing Around the Power Supply Circuit And Find U3 a RT8279 step-down regulator to Be Shorted.

So, I was Feeling Lucky and I Checked the Capacitors in the power supply circuit but the Short Remained.

After the Capacitor check, I Removed U3 and the Short is Gone. We have a Winner!

A Little Voltage Injection and we have Some Signs of Life So Not a Lost Cause Yet!!

Repair Updates for the Tormach ECM1 V1.5 Control Board will be a bit slow due to no one in the USA having stock of the RT8279? I  have ordered the chip it From China ETA October 03! If I am able to collect a donor board or two for parts I will update any progress.

Some Parts Arrived..

Price breakdown of parts is under $1.00 so far.
RT8279 at $0.73ea + ship or 0.85ea in 20 lots shipped On Aliexpress (Middle Range Vendors) If Digikey/Mouser had US stock about $2.20ea.
1N4148WS-7-F Diodes On Aliexpress about $0.04ea shipped If Digikey/Mouser US stock .09ea in lots of 100 or $0.19ea

D22 & D23 Installed.

Replaced U3 with New RT8279 Signs of life once again!

Tormach ECM1V1.5 repair step-down regulator repalced.

When Hooked to PC and Ethernet Cable I Can Ping it and get a response. Now need to figure out the required wiring for path pilot to initialize the board.

09/28 Tried a few different setups was not able to get it to talk to path pilot yet. When I get the free time I will to go thru the machine wiring schematic and make a test harness.

10/13 Tormach Released a Statement on YouTube about Them Supporting the Right to Repair.
From my inspection of the ECM1V1.5 and ECM1V1.4 Control boards it seem to use all off the shelf parts which is a good thing.

I am a Tormach PCNC 1100 Owner and I Have sent an Official E-mail Request for the Control Board Schematics.

Regardless what Tormach says Publicly In My Opinion Tormach Does Not Support The Right to Repair Audio Of Our Conversation.

Louis Rossmann Reacts.

I have been in communications with Tormahch’s CEO Rogge. My opinion has changed Tormach is now supporting the Right to Repair. Tormach Just did a Repair Document Data Dump https://github.com/tormach/Repair-Information Wow!! What I was told will take them a few days or so to get it all uploaded.

#righttorepair

Seems Tormach Went Silent and Have not Completed the Right to Repair Document Dump appreciate what they have given.

Update:11/09

This board is fully working was not a FPGA issue but a faulty 93C46 blocking Ethernet coms.

12/2022

I have repaired about two dozen of these since the schematics were released it Seems U3 is a Common Failure in these ECM1 Boards and a Few other Small items and people bricking them having to remove and reprogram the flash at U12.
