Title: super Glob bootleg on Pengo hardware Post by: Zabanitu on January 15, 2012, 07:56:42 PM this bootleg superglob runs on pengo hardware with crypted roms and bootleg crypto cpu !
the board had wrong sync: the frame was stuck at mid screen and there was garbage on screen. afte checking the sync circuit i found a half faulty LS107 flip flop wich feeds 6Mhz clock to various parts of the board - replaced with a LS73 (different pinout) since i didn't have a spare 107. the fault was strange since the cpu clock (3 Mhz) worked and i could run tests with fluke 9010a, but the video part of the board simply wouldn't work. the board also has the ancient AM25LS2519 and not a bootleg replacement. to disable watchdog just ground pin 15 of the LS161 @ location 23. dumped the encrypted and decrypted roms (using the bootleg cpu adapter), very similar to superglob german running on pacman hardware, it's in english and with (c)1985 ELSYS SOFTWARE displayed.

If you ever need them I have some of the AM25LS2519 chips in stock. They are extremely hard to find. RJ |
