REX does not use any IO ports. Good luck with your project. Steve On Fri, May 10, 2019 at 4:51 PM Dan Higdon wrote: > Hello all, I'm a new M102 owner (the last two months).

[M100] Hello, and REX question
Hello all, I'm a new M102 owner (the last two months). I've been having a lot of fun messing around with my new little friend. I just recently purchased a REX chip for it, and I have a question about how the REX interacts with the system bus. Specifically, does it use any of the expansion i/o port addresses. and if so, which ones? I ask because I'm considering breadboarding the simple parallel input/output circuits in that "inside the model 100" book (probably not the actual title, but I'm not near my pdf of that book right now.). I have it in mind to generate 8 trigger/gate signals to control some analog synthesizer modules, and I don't want to accidentally corrupt data in the REX by outing values to a port that's being used for something else. (I realize the ModelT's performance may not be up to precision drum machine standards :), but these sorts of projects are fun for me.) Thanks in advance for any details, Dan Higdon
