      From: kelvin@pro-kegs.uucp              From "Cortland Custom ICs - Wayne Lowry - Preliminary notes - 19860214"       (via https://www.brutaldeluxe.fr/documentation/cortland.html)              The Mega II is the integration of several enhanced Apple II chips. The       following chips comprise the Mega II:              * MMU Custom Chip       * IOU Custom Chip       * Character Generator ROMs (8 languages)       * TMG Timing Generator       * GLU General logic Unit       * Video logic              The Mega II, shown in Figure 10, has virtually all the characteristics       of an Apple II on a chip; it supports a slotted architecture and has       built-in peripherals.              ---       It's possible that everybody, including Apple, has been wrong for 37       years but extraordinary claims require extraordinary evidence.              -------       ProLine: kelvin@pro-kegs              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
