    Quoted from wiredoug:

    wow i didnt know you did one.. if its half as good as your gottlieb one i would pay for..

    Thanks Doug, you've got some email.....

    For everyone who wants to try the Williams testrom, please send me a PM with your email address. The video above is obsolete as I tweaked the testrom over the years a few times. Compared to Leons' testrom it has some more reliable memorytests, it tests the IRQ generator, it has an input test for the switchmatrix PIA, it has a PIA init test and it can test the U14 and U20 rom sockets with an additional testrom. In a nutshell. Due to the additional tests it might be a bit more difficult to work with.

    Andre's testrom is also a nicely programmed testrom for Williams which can obtain good results.

    Nice! Thanks for your feedback. Certainly a lot of work but really worth it!
