Zaccaria/Associated Leisure Mr. Do! Restoration

Background

This was a game that I helped a fellow UKVAC collector buy in the 90's before I became a Zaccaria enthusiast. He left the country and the game came to me. For a long time I thought this was just an operator conversion of a Zaccaria Universal (not Universal the game company but universal as in for any game) cabinet but then a flyer with this cabinet for Mr. Do! surfaced. My game has Associated Leisure serial numbers on the parts inside it.

Zaccaria/Associated Leisure Mr. Do! - front Zaccaria/Associated Leisure Mr. Do! - front Zaccaria/Associated Leisure Mr. Do! - left

The cabinet looks basically solid. There is a small crack in the marque and the original glass was broken a while ago so it has a Quasar glass in it now (I have a Phoenix that has the star glass in it that I can swap with this one to correct both games). The cardboard monitor surround is also torn up.

Control panel Cigarette damage Universal license seal

The control panel woodwork has been so well used the paint has been worn away down to the wood on the edges. The joystick has been changed and the holes in both the wood and the overlay widened to accommodate the replacement. The player select buttons are vandalized and the control panel overlay has the worst cigarette damage I've ever seen :(

22/10/2012 - Internal assessment

Zaccaria keys

Looks like I have a full set of keys for this cabinet including the original Zaccaria stamped keys :)

Zaccaria/Associated Leisure Mr. Do! - inside, bottom Covered external degaus button Audio amplifier

As far as I can tell it looks like the internals are complete and all original. There's a wire broken off the audio amplifier and I'm not sure if it originaly had a proper connector or was built direct wired. Oddly there is a metal plate over the external degauss button (still present and wired in the cabinet but not plugged into the monitor).

23/10/2012 - First power on

Plug change over
A picture, no boot

First power on with AC only gave 125V and 210V on the monitor connector (versus spec of 128V & 220V). The marque light doesn't work and there are no coin door lights. With the DC side on, the regulated power supplies came in at +11.97V and +4.71V, looking reasonable. The +5V will probably go up with some light cleaning of the connectors. With the monitor on there was a picture of a few sprites. The game PCB doesn't boot. After a few minutes the monitor vented an acrid smell - capacitor failure.

25/10/2012 - Wiring

Edge connector, front Edge connector, side Terminal block

The edge connector is missing a pin (top right) and looks like it may have been changed once already judging from the solder on the unusued eyelets and the lack of shrink tubing. It needs replacing again I think. The fan has probably been replaced - it's not the metal caged one that I usually see in Zaccaria cabinets and it's connected via a terminal block.

Control panel, back side Marque light tube

The back of the control panel shows the "modern" joystick and notes written on the back of the wood by whoever changed it. The two shoot buttons appear to have been wired together though it should only have one button. I wonder if this cabinet was converted to JAMMA at some point? Likely reason the marque light doesn't work is because the tube is floating around in the cavity.

Fan wiring tidied up Amplifier wiring tidied up

Though I'm not going to reconnect the fan (I always disconnect them because they're almost always shot and this one is no exception) I still replaced the terminal block with a proper splice and neatly tied up the excess cable. I also fixed the broken wire to the amplifier and secured the cabling for it. It doesn't look like the amplifier ever had a proper connector on it so I've left it direct wired as is for now.

Mr. Do! on the bench Mr. Do! not booting

Built a Universal to JAMMA adaptor for testing the game PCB on the bench. Still no boot, pretty much the same as it was in the cab.

Zaccaria universal

I went hunting around for a spare control panel with a good overlay and joystick All I found were a couple in the same style as the current 2-button one that's on it (both in better condition of course). Then I noticed that the control panel on my early universal cabinet (the 2nd game I ever bought and the 1st Zaccaria cabinet I bought that started it all)...

Zaccaria universal control panel Zaccaria universal joystick Zaccaria universal button

... that has a 1-button control panel that matches the Mr. Do! flyer. What else do we have here? The joystick collar has "UNIVERSAL" stamped on it :) I have no other control panels that have this type of joystick fitted. I also noticed that the control panel wood isn't blue so it doesn't match this blue cabinet. The "UNIVERSAL" joystick doesn't match the Mr. Do! flyer that shows a standard Zaccaria silver rod stick but otherwise it's a perfect match. My take is that the flyer is an early version and the "UNIVERSAL" stick more than likely did ship in the game. The 1-button overlay is just a slightly modified print of the 2-button overlay but with one button covered over with a gold splat.

Mr. Do! instruction card

Scanned in a Mr. Do! instruction card I found in the bottom of the EU Money Money. Alas, the size and style is not the same as the one on the flyer but it might be adjustable to fit the window on the bezel until the "real" one turns up.

A simple cut and paste yields something that might fit when printed at the right scaling.

30/10/2012 - PCB work

Bad 74LS138 out Bad LM324 replaced Mr. Do! working

The game doesn't appear to use a watchdog so I set up my pulse injector to do 400pps on the Z80 reset line to keep the CPU trying to run. Looking at address and data showed all the signals active on the Z80 but the data bus looking a bit mushy on the scope. Moved on to see if the A/D looked OK on the EPROMS (they did) but found pin 22 CE always low on all the EPROMS. Tracking back to the 74LS138 found all outputs low/floating but the inputs looking OK. It was dead. Replacing it allowed the game to boot and run but with no sound. The sound is output via an LM324 preamp. The first stage of the preamp looked OK but the last stage had no output. Replacing it brought the sound back and it's all working now :)

01/11/2012 - New edge connector

Pre-linked edge connector Replacement in progress Replaced edge connector

I put in the various links for the power and player 1 and player 2 and pre-cut three sizes of shrink wrap (single, double link and quad link) in advance. With that done transferring the wires from the broken connector over to the new one was straight forward. I'll leave the shrinking for after everything is working.

First power on with working board

The new edge connector worked fine for all controls and both players. The monitor has problems - degauss is not working (manual or automatic), the focus is off and won't adjust out but seems to get better as it warms up, the picture is not that bright even with the contrast and brightness both up full and one or more caps are still venting an acrid smell :(

03/11/2012 - Odds and ends

Odd wires Access panel off Cardboard surround

There were a couple of odd wires on the wiring loom that traced back to the control panel connector and were unusued on the control side so they just need to be tidied up. Removing the access panel allowed the marque light assembly, cardboard surround and marque to be removed. Looks the a whole new surround is needed as the one that's in there has large tears and is missing the lower portion. It's plain black so should be straight forward to reproduce.

Cutting a screw head Slicing the nut Marque light working

Of the six marque bolts only one was seized but it was really seized - the usual trick of cutting a screw head didn't work so it needed the nut cutting off. The marque light worked with the tube refitted.

04/11/2012 - Monitor work

Hantarex 900 chassis out Fuse and holder corrosion
Missing East-West PCB Bad capacitor

The monitor chassis fuses are heavily corroded and the one that protects the degauss circuit had the wire inside corroded off so I'm hopeful this is why the degauss isn't working (the fuse hadn't blown). The east-west PCB is missing but I should be able to find one off a scrap chassis. The same cap appears to have gone bad as the Zaxxon chassis so a cap kit is needed. Some work to do.

07/11/2012 - Retest

Hantarex 900 running

Cap kitted, fuses & holders replaced and some other miscellaneous minor work got a useable picture out of it. When cold the focus is way off but settles down when when it warms up. Will leave that as is for now.

08/11/2012 - Control panel work

1 and 2 button control panels side-by-side 1 and 2 button control panels back to back The two connector formats

The 1 and 2 button overlays are indentical execpt for the gold splat that covers the 2nd button hole. It looks like Zaccaria added the splat layer first and then applied the remaining 2 button paint layers on top - up close the 2nd button artwork can be faintly seen underneath the gold splat.

One other variation I didn't notice before is that the two control panels have different wiring connectors. The right Mr. Do! control panel I found on my other cabinet has the wrong connector for this Mr. Do! cabs wiring :(

Attempting to polish out the cig burn As far as I was willing to go with it The donor panel stripped down

This spare control panel I found from a mini cabinet will donate it's overlay and joystick to replace the ones on the universal. The universal overlay and joystick will go on the Mr. Do! cabinet. The overlay has some serious cig burn that I tried to polish out. It's still not great but better than it was.

The existing control panel has the joystick hole drilled out to make it bigger however the original joystick still fits. The overlay and Universal joystick collar cover the hole nicely.

Chrome stick spring, horizontal size Chrome stick spring, vertical size

The donor control panel is fitted with a spare two button overlay and standard chrome shaft joystick so it can go back in the cab it came from (it'll need a blanking button in the hole as it's only wired for a single button). The spare joystick has a broken spring that I need to find a replacement of.

29/11/2012 - PCB mounting plate

Marking the mounting holes Marking the PCB holes Plate mounted

The cabs is missing it's orginal PCB mounting plate so I ordered some replacements based on the scans of the Super Cobra plate I took a few weeks ago fron OnlineMetals.com. I ordered 16.875" x 11.4375" in 6061-T6 aluminium, 0.9" thick that fit OK but I'd go with 0.75" next time.

30/11/2012 - Cardboard surround

Marking monitor cut-out Monitor cut-out
White edging Black edging

The surround in the cab is torn and missing the bottom piece so I decided to try to repro a new surround for it. I found a thicker "4-ply" cardboard sheet at Ben Franklin that they cut to the correct size (23 5/8" x 39") in the framing department. I used the original surround as a template to mark the monitor cut out. Despite my very poor art skills the monitor cut out ended up not too bad. With a card being white with black laminate I needed to use a black Sharpie to make the edge of the cut out black. Pretty happy with the way it turned out but...

Getting the surround back in Surround in

The card was too thick to be able to easily manipulate it back in the cab and the back curve was too sharp for it so it ended up creasing :( Tried taking it out, flattening and reinforcing it for a second attempt and it still creased in a different place :( Decided to leave as is for now as a an experiment with lessons learned.

04/12/2012 - Monitor troubles

No blue No blue and almost new green
Where the cap goes TDA 3501 equals Hantarex 20620200

The green on the monitor had some intermittant brightness issue and then lost blue completely :( Replaced the colour pre-amplifier IC socket (that looked like it was the cause) and the colour pre-amplifier itself but it made no difference to either issue :( Leaving it for now as I need to build a monitor test fixture to fault find it on the bench.

06/12/2012 - Credit button

Shrink under wrap Shrink over wrap Credit button fitted

Finally remembered to order some push buttons to use as credit switches. Simple to make and fit in the coin slot.

07/12/2012 - Instruction sheet

Sizes to choose from Fitted in the window

Printed out three sizes of the instruction sheet I made above and picked a winner. I used a tiny dot of glue in each corner on the plain area to hold the sheet in place. I forgot to account for the control panel obscuring the bottom of the glass - another lession learned.

08/12/2012 - Finshed for now

Zaccaria/Associated Leisure Mr. Do!, front, flash Zaccaria/Associated Leisure Mr. Do!, corner, flash Zaccaria/Associated Leisure Mr. Do!, front, no flash Zaccaria/Associated Leisure Mr. Do!, corner, no flash

It's all done for now except for the monitor issue that I'll come back to once I have a test setup in place to work on them.

11/12/2012 - Monitor test rig

Konami Super Basketball IGR power supply (EU) Hantarex video cable splicing

I needed a game PCB to use as a video signal so I followed the the rule of old game boards - if the game is poop it'll work perfectly. No exception to the rule here, the Konami Super Basketball worked fine :) The IGR EU power supply from the old EU Money Money provides the dual power for Hantarex monitors. The video cable from the same cab spliced into the 15-D (VGA) I use on my test rig. All set.

13/12/2012 - Monitor test rig part 2

Monitor on the bench First power on After tweaking

Found a dusty old monitor in a none-standard frame (thus not easily reused) as a suitable tube to run chassis on the bench for testing. Didn't expect the chassis on it to be working but it came up and tweaked to a very nice picture. Spare working chassis are always useful. Next is to fix the Mr. Do! chassis.

03/01/2013 - Monitor test rig part 2

Diagnosis First power on R142 focus voltage 10 minutes in R142 focus voltage

The Mr. Do! chassis had two issues - the first was that the picture was out of focus on initial power on. The second was that there was no blue. Already swapped the RGB preamplifer socket and the amp itself so I knew those were OK. The whole lot just squeezed onto my bench to be able to poke around with a scope. No signal on R79 out of the preamp. Using the diode check on the multimeter indicated a fault accross BE of TR11. Took at stab at TR11 (BF871) first but was wrong. Turned out it was D18 (1N4148) that was bad and replacing it brought blue back. The focus issue was clearly a measurable drift in the focus voltage as something warmed - these sort ot warm up focus issues have often been a bad LOPT in the past but since replacement LOPT's for the MTC-900 series are no longer available it can wait for final failure.

06/01/2013 - Done!

With the monitor chassis back in the cab the picture looked very good after 10 minutes of warm up time.
