ONLY 1 question how can u play Galaga on lcd must be like 2ms responce or is it a Computer monitor LCD?
I being 40 and growing up playing on 19 inch CGA screens must have the 15Khz mode complete w ROASTED contrast ,
NOT to mutch not to little Hit it just right ... from Caddy shack II....
anyway looks nice bright too!!!!!!!!!!!!!!!!!!!!!!!!!!!! also the mini LED marquee looks cool too .. and NOS sticker on Control panel looks like
you just removed the backing and just pressed it on that day you took pic!..
whole thing looks mint I would turn it off put 50˘ in then plug it back in then put a nother 25˘ in and play just to GIVE u 50˘ cause cabinet looks nice...
If i was there i would just hand the LUCK $ over...
Ps have you shot all bees down in demo tracktor mode to watch it reboot ... its cool..
also if its a REAL Arcade pcb? i forgot by now I think Mikes arcade still has HIGH score kits w dip menu on and in menu so you wouldnt have to futz w dips...
I just restored the POWER panel on my WIZ wor cabinet now a NON dedicated DEDICATED Mr. DO! cabinet... ill try to U load pics..
The whole time I thought my problem w MRdo was a chunk of solder on the z80B chip naw it was bad power going into arcade power supply so i removed
the HUGE midway transformer witch was not hooked anyway removed its fuze then relized the small one was a isolation/12v AC transformer one winding took 110V or 125V or 220V ac in to 115V Ac out for screen Wells Gardner k4616 4600 series CGA arcade monitor and the other winding gives out 12vAC for cabinet 25˘ lights! the saftey switch DOES NOT turn off the CONVIENCE outlet I was like HMM.. I found out the arcade power supply sucked it wont shut down like a compaq spare would if i shorted a chip on pcb so I swapped those. found out power AC 110V going into the arcade power supply had bad CRIMP
I called Todd from Summit amuzement and left a message YOU BETTER CHECK YOURE CRIMPS in this machine when it was a klax kit it looked like if there was a bad crimp somewhere there would be MORE shure enough .. anyway that was causeing mr do to reboot like static on line MADE me ferous I played 110 boards only to have it reboot YES i was using the free credit button on cabinet to short the rack advance dip switch but i wanted to make shure game would play . now It works like a charm.. then I mounted Compaq spare i think it was a k6II 450Mhz board i stole power supply from.. kept chip threw board..
I also replaced soldered all connections on transformer fixed a bad crimp on factory saftey switch at 1st it stumped me cause all pins on saftey door switch worked even if i pulled it out! but NO power to screen or flourecent Lamp on Marquee WTF i thought so i pulled connectors off saftey switch only to find one came out of its crimp This was AGE and A Factory 1981 crimp from Midway! I replaced crimp connector spade and replaced saftey switch now it works played 11 boards just as agressivly and hyperly w sound LOUD ;,.
I got lucky on ebay when i got the Mrdo pcb it has a Built in Sound amp!!! i think it might be running off 5v too I forget anyway even driving the 3 speakers from the WIZ wor it is LOUD ENOUGH to hurt youre ears its hard to adjust to normal V.
I also noticed since the COMPUTER power supply the compaq spare is plugged into the conveince outlet i can Run the Mrdo pcb w screen and cabinet power OFF saving $ and high score...
The Bking II in the same cabinet is A project thats off line untill i get a small RAdio shack sound amp to replace the one i have now witch is using up one of my Atari 800 power packs and now that i know its in there im taking it back! plus i should beable to find a crappy computer speaker system and chomp it to run off 5v instead of 12 if im lucky!! the cool thing about the compaq power supply or any atx power supply is it has -5v 12v 5v+ and sometimes 3.3v so if i ever need to run a It game like golded T I can just use power supply! Plus the thing i like the most is im not running lights off the compaq supply I run those off the iso transformer witch has to be on for the screen anyway... this leaves lots of 12v for things like marquee lights 12v computer fans and what not..
Pics before after huge is the WIZARDS OF WOR power supply no need then jamma jumble resting in coin box I guess Atari klax kits
figure you need 3 thousand feet of jamma wire...
now that i uploaded pics and can see what order they landed
ok pic 1 is board stripped off before I windexed it Last pic is after windex and whiped Note the cool 1970's wood grain on a REAL peice of plywood
not fiber board like todays crap Namco makes!!
2nd picture is back inside cabinet slid in note the white box on left thats the saftey switch cover i had to remove and replace a crimp on I was so happy to find out that was problem.. it took me the most time to figure out what the hell blue and brown ment vs Ac wireing I made DOUBLE DAMN shure I got that right it just didnt seem right that using a car fuse between two of the fuse inputs to get coin door to light seemed just wrong 0v was missing I finnaly found the loose crimp on saftey switch and it workd and is correct only blew one fuze That was purley a learning curve fuze anyway The windings in the isolation Transformer are totally seprate the 12v ov is NOT even close to the same as the 110v 0V besides the 110V 0V has to be different cause its a isolation one!! DUH I should have known that ... I just stole the same rating slow blow fuse from the non used HUGE transformer in pic 5.
ok pic 3 shows moved filter block... and picture 4 shows jamma jumble and power supply resting in coin door along w the $5 audiophile amp I used for
birdi king II witch i now have to replace since the compaq power supply stole the convience outlet plus I need a 12v or 5v one anyway I dont like the Atari power pack floating around anyway... and not least but last here is picture of the trackball . OK its a thumbball...
Next post i will keep my promise and show the inside of the wico control from bking so you can see the iso optolator wireing..
you know 5v+ is red and gnd is black..
then its just up down left right..
this means it has two recive infra red recivers in the up down wheel at 1st i thought there was only 1 recive led(ir recive led) there is two..
so total of 4 the transmit ones always get 5v+ the other ones get 5v+ then have extra leg for output!.......
anyway there are 2 more pics one of the control panel showing the white thumb wheel i used for bking and some crappy notes i used for joystick at one time to note the klax jamma wireing color code incase i ever replace thumbtrak w a 2nd joystick...
Next i will post pics of Wico control...
