    Quoted from G-P-E:

    What are you doing about game ROM's?

    The board uses your original roms, or you can buy a fresh set from the copyright owners to use.

    Back from the UK Pinball Party (this weekend just gone) and now assembling boards. This one is destined for The Goonies Pinball Project.

    I'm not sure if this was asked before, do you sell just the board and parts?

    I'd love to solder one up on my own.

    Or even just the bare board, with a parts list?

    Quoted from Whysnow:

    great.
    As an owner and lover of both TX and Robowar I will be buying 1

    Same goes for me!

    Yes you can buy a full kit or just the bare board if you'd like. I have a BOM (Bill of Materials) that i can supply. Contact me directly with your email address.

    Thanks so much for the little extra love on this. The custom text for the display will be the icing on the cake for my project.

    #59 2 years ago

    Looks great. Respect for your achievements and putting so much effort in this!

    #60 2 years ago

    Just a quick update for people wanting the blank board to assemble themselves. A little autumn/winter project maybe. I have a full Bill of Materials with all part numbers for element 14/farnells. I am also happy to guide you through how best to assemble them.

    The cost here would be £60 plus £7.50 shipping standard or £15 shipping tracked to USA. I can work out a US dollar price to if that works better for anyone. (I am in the uk :)) Payment is via paypal.

    Thanks

    #61 2 years ago

    Buy with confidence from Jim. Shipping actually does not take long to the US.

    Great work again Jim.

    Goonies pinball has a pulse. Power supply tuned in and the new 80B board installed with custom ROMs. Looks great Jim!

    Didn't notice until now. There appears to be a header to replace the TC1 connector. If so, did you remember to 'swap sides' on the pins so that it would work with any DIP adapter cable? Or with a standard ribbon cable where the DIP connection was presumed?

    Pinouts, for example --
    DIP:
    Pin 1 Pin 40
    Pin 2 Pin 39
    .... etc

    Header:
    Pin 1 Pin 2
    Pin 3 Pin 4
    .... etc

    In converting from a dIP to a header, people often just tie pin 1 of header to signal that was pin 1 of DIP (DB7 for this board), pin 2 of header to signal that was pin 40 of DIP (AB4 for this board), etc. BUT - using an adapter (simple ribbon cable) does not follow conventional pin out and the left and right sides must be swapped. The result would be what was pin 1 of DIP (DB7) would be tied to pin 40 of DIP on the opposite end.

    Put through a ribbon cable DIP to header adapter without swapping:
    DIP pin 1 would connect to opposite end header pin 2.
    DIP pin 40 would connect to opposite end header pin 1.
    DIP pin 2 would connect to opposite end header pin 4.
    DIP pin 39 would connect to opposite end header pin 2.
    ... etc

    So pin 1 of header must be what was pin 40 of DIP (AB4) and pin 2 of header must be what was pin 1 of DIP (DB7).

    Lets say somebody used the TC1 connector with a cable that has a DIP plug on one end and 40 pin header (or DIP plug) on the other. If you then change this TC1 from a DIP connector to a header connector and that same person then tried to use this TC1 connector with a simple ribbon cable - it won't work The left and right sides would be reversed - you would be putting 5VDC down their reset line and vice-versa.

    I do include a header output on the board labelled 'Debug/Mod Header' which is an optional install. The premise for this is to add an option for future add ons or test cards that i may, or other people may build in the future. It is not meant as a direct replacement for the old TC1 header, but does include all the useful address, data and control signals you may need for such mods etc.

    Currently most orders are not populated with this header as people mostly just want a plug and play replacement for their dead original. Fixing of my stock boards is also a much easier job these days with the more advanced test roms available, the leon test led pre installed and the use of full sockets, so the old TC1 header isn't really needed. I have had a few boards back to repair after users have shorted voltages to the switch matrix etc. These have all been easily fixed and returned to continue their lives keeping old gottliebs running
