Since I happen to have an official Motorola manuel on this chip, I can tell you this. Interfacing the chip to a COCO will require extensive modification to the motherboard and to the 40 pin extension bus (assuming that you have a plugin that can use DMA). Plus you'll have to add some "glue" logic to get the correct signal syncronization!. Not an impossible, but certainly not easy job to undertake! -- Thomas Kocourek KD4CIK :UUCP on an OS9 system, UUCP: dragon!westgac3!tomk :Multitasking & windows in INTERNET: tomk@westgac3.dragon.com :512Koctlets COCO3 INTERNET: tomk@westgac3.atl.ga.us :Lotteries are STUPID TAXES, IMHO.
