after 3 (in words: THREE) hours on the phone this afternoon with joerg and a lot of probing, pulsing, measuring, wire hacking and schematic reading we THINK to have narrowed the problem down to the coin door and its wiring. if joerg wants to chime in and explain a little bit further, please do so ... Wink i can't thank him enough for his help so far!

I can try to explain a bit what we found out Grin The coinage on the JK board is a little more advanced that on other pcbs. On the poinout of the board there are three pins for each coins slot responsible for coinage. First there is the coin signal itself, coming from the coiner, on the second pin comes the coin lock signal, which goes to the lockout coils and third pin on the pcb edge connector is the one for the coin meter. If any of these are not connected or functioning right, no coins are accepted. Problem now was that Ullys coindor was not an original one ... missing counters, hacked wiring and stuff. So the pcb failed to work properly. That's a long story short. Very short. Grin

Btw. it was great fun to work with Ully ... I had some of these phone support sessions with other people and it was a real pita because they simply didn't follow the instructions. This time it was great and after an hour we got in that "tunnel" completely focused on the schematics, finding ideas and trying out stuff. That was great fun although Mrs. Caveman was a bit "irritated" that I spend the whole afternoon on the phone Wink

We think skype comes from the devil here in germany ... it's rarely used, at least not from people who wear shoes while eating their breakfast. Grin

SKype or MSN could come in more handy, since you can use a webcam then..
Or do you guy's have videophones ?  Grin

Hmmm .. Ully was very busy just holding the probe in one hand, wire to bridge some pins in the other. I think a webcam would have killed him or at least gave him a terrible neck injury.

Webcam ain't such a bad idea and using a headset with a microphone ain't that bad either - we need to think about this the next time we do this! Grin

Just stumbled across this by accident:

"OK, another titbit related to Taito SJ Hardware
I found a fix for Elevator Action that wont coin up execpt using the service switch.

I found that after I converted a Tin Star back to Elevator Action using the bootleg roms, the coin inputs wouldn't work. Looking at the schematics made me realise that the link from the Counter Drive wasn't connected. All I had to do was add a link between the common and 2 and all is well."

I have no clue what he is talking about but maybe it's of any help? He also mentions a pic that he posted but there is none  Grin

I haven't got anything to contribute on the tech discussion here, sorry. But my, this is surely one of the coolest - if not _the_ coolest restoration thread I've ever read. Deeply impressed by your paintwork a few pages back.

thx man, but i'm pretty sure scr33n's paint jobs are nicer / smoother than mine, but then again i have the better color combinations Tongue

regarding the tech stuff: problem has been located and fixed, just can't update the thread yet because i'm still missing a crucial piece which should hopefully arrive soon!

while waiting for the "tech stuff" to arrive, i'm concentrating on another aspect of the artwork: the monitor bezel! in case you don't remember, i wasn't able to find a nice glass bezel for my cab (most of them are badly flaking), so i grabbed an art file from joemonkey and had it printed arrow



while it looked ok at first, there was some stuff which didn't make me happy, for example the masks and the tarzans at the top not "reaching" into the visible area. have a look at an original bezel to get an idea what i'm talking about arrow



additionally, the colors were off (too dark) and it had the instruction card "included" in the artwork, the original bezel came with a seperate card which was fixed to the bezel from the back - have a look arrow



because of that, i got together with our vector king etienne who kindly agreed to take on the task of vectoring the entire bezel for later reproductions. there's nothing available in the usa, although a jungle king bezel is probably one of the most desired pieces of art out there. so for a couple of weeks / months, etienne and i exchanged tons of emails about the progress he made and some corrections from my side. here's what such a file looked like after etienne had sent it to me and i had added my remarks arrow



etienne was almost done with the bezel (and the instruction card) when i was contacted by a guy from KLOV about an original jungle king bezel in ok condition. i was totally torn about what to do, because etienne had spent endless hours on this and now that the end was near an original piece came along. so i contacted etienne and asked him what to do and without any hesitation he told me to go for it! i was still hesitant because i somehow felt i betrayed the vector king, but of course an original bezel is somewhat nicer than a reproduction PLUS it was much cheaper than having etienne's version printed, so i decided to get it. who knows, perhaps etienne will finish the art and make it available for possible reproductions later!

enough said, a huge box arrived through "personal delivery" Wink at my doorstep one day



good news: everything seems to be in one piece!



a first careful peek inside already reveals some flaking art Cry



let's inspect the worst spots a little bit closer arrow









as you can see, some serious flaking going on - and of course i can't leave it like that, so first of all i'm taking out my black "glass pens" ...



... for some first minor corrections!





after that, i'm bringing out the heavy artillery: my touch-up colors!



which shade of blue fits the best?



here's the bezel after touching up the art, first two photos are against-the-light shots, last two bezel lying flat on the table. doesn't look too nice, does it?









let's see how this "nastiness" turned out on the visible side





as you can see, close to perfection in the lower section, in the upper section the blue came out perfectly, but unfortunately the green color - which was an almost perfect match when applying - darkened after drying and so you can clearly see the spots where i touched up the art. however, this is going to be almost invisible once the bezel is installed and it looks so much better than when i got it, so i'm really happy with the results!





it's not perfect, but good and original! note that the flash increases the color differences



now that i'm done with touching up the art, i want to seal it to prevent the bezel from flaking any further. here's what i'm using arrow



setting up my personal "paint booth"



while "shooting", i'm protecting the visible glass areas with cardboard



still missing: the instruction card!!! stay tuned ... Cool
