Hello Group,
This is the forum that I have been using for my hobby, so maybe some of you can help with the following.
I need to figure out the equations of an old PLA (82S153N, https://pdf1.alldatasheet.com/datasheet-pdf/view/110789/PHILIPS/82S153A.html)
Just for context, this is used in the Ensoniq Mirage synth, but if you google it you will find that it was a staple in arcade games.
I was wondering if anybody here has experience with using our beloved Teensyduino for such purpose.
What concerns me (and this is where I do not want to waste a lof of time) is that this device's pins can be used as tristate pins, so it is not the traditional memory ROM dump.
Thankfully there are no sequential elements inside!
If anybody has already written some code for the Teensy for something like this, or has some good pointers, I'd love to hear and learn from you.
Thank you!
