mjnurney Posted January 17, 2021 Share Posted January 17, 2021 Hi guys, do we have any Mattel Aquarius experts here? I’m not sure if I’ve asked this before? I have a unit that works, powers up fine. Keys work and it’s clean but it will not detect any expansion, RAM and external carts are not detected. cart port is in good order, clean and has been buzzed out - all of which is fine however no cart is detected.

MackJsy Posted January 20, 2021 Share Posted January 20, 2021 (edited) I had one that was the same, turns out it was a faulty Z80 - seems there was a problem with the A15 line Replacing the Z80 sorted it out.
