Title: olymipc problems Post by: boofhead68 on July 30, 2013, 02:39:29 AM l have a Olympic Night owl that used to work fine, it used to come up with logic seal error but it would clear in service mode but now it will boot and load to the logic seal error comes up but when l turn the key nothing happens, l cant get into the service menu, the door alarm doesn't chime or the door open warning doesn't come up, checked the switches are working and the power supply has the required voltages but nothing is working.
Does anyone have any ideas? Thanks Title: Re: olymipc problems Post by: Gaming1 on August 16, 2013, 09:03:45 PM Sounds like a oa2 that needs ram clearing

So l need to replace the ram chips because the ram clear button does nothing? Will unplugging the battery do it or will that wipe the whole lot out? Thanks again I'm really keen to got it going again? Title: Re: olymipc problems Post by: Gaming1 on August 21, 2013, 07:32:51 AM They are special programmed EPROMs
Title: Re: olymipc problems Post by: boofhead68 on August 21, 2013, 07:49:40 AM So do I need to get new ones or can they be cleared?
Title: Re: olymipc problems Post by: Gaming1 on August 21, 2013, 07:52:23 PM They are like the game EPROMs you need to burn them with EPROM programmer on to 512 EPROMs
Title: Re: olymipc problems Post by: chemstar on August 25, 2013, 08:14:53 PM What gaming1 said is right except the main board reset chips use bigger EPROMs
I have a copy of the reset roms if u want to PM me. The I/O reset is a 27c512 And the game reset chips are two 27c010 that are placed in the symbols eprom sockets on the main game board. If u don't have a programer I'd burn for u if u send me the chips. Title: Re: olymipc problems Post by: boofhead68 on August 25, 2013, 10:52:28 PM whow this is getting heavy!!!!
thanks chemstar I'd like to get this machine going again and l don't have a programer and l can send you the chips but first can you give me a run down on whats going on, the machine worked fine and one day just stopped, I'm by no means a computer expert but l do understand a bit about them its just for my understanding of the machine that's all. if l post a photo of the board can you point out what chips need to be removed? Thanks Title: Re: olymipc problems Post by: chemstar on August 25, 2013, 11:32:10 PM Post pic of board then ill take it from there
Title: Re: olymipc problems Post by: boofhead68 on August 26, 2013, 12:53:32 AM cant post the photo on here as it is too big can l send it to a email address?
Title: Re: olymipc problems Post by: Mazwreck on September 12, 2013, 10:25:12 AM While machine is off take out eprom ES3
Turn machine on wait for olympic boot screen press red reset button Turn machine off put eprom back in and set machine up but you may need to use a I/O clear on the smaller pcb in the tray (somtimes i got away with just resetting with removing the eprom) If you get it to reset and buttons do nothing even after using I/O eprom then i have no idea i had a few pcbs like that could never fix them |
