Greetings,
I have an extremely rare Cocktail Pinball machine made by Valley in 1978. My machine is one of less than 20 that is known to still exist and one of 3 or less that acutally work. Getting my machine to work has been a long journey and I am very close to having a fully working machine. However.......
The code that was extracted from the ROM has been found to faulty either due to corruption over time or the extract process itself. It is also possible that there was a bug pre-existing in the code.
The Visual Pinball MAME group of programmers managed to dis-assemble the 6502 code and I have both the BIN file for the code and the TEXT assembler code.
I need someone who would be interested in looking at the code and helping to resolve the issues with in it. Besides myself there are several other owners of this machine who are looking for a viable code set and one we can load and use in our machine.
You can find out more information about this project through my personal webiste's projects page. Navigate to
www.rustykey.com and then select projects and then Spectra IV. You can also see information on it by searching Spectra IV on Facebook where I have set up a page for it as well. I hope to update my personal page very soon with the latest information.
Any assistance in this effort will be greatly appreciated and you will receive accolades and credit on the various websites as we proclaim the fact our machines now function correctly and who all helps us get there.
If you are interested in helping, either leave a message here or send me an email. I am not sure of the restrictions on this website (just joined) but I will try to post the binary and text files along with the other informaiton I have this evening.
Thanks in advance for any help you can provide!!
