As some of you know, I have a batch of Magnum STs that I had made. I have had the MACH210s programmed succesfully as the TOS 2.06 upgrade works. The Magnum ST driver doesn't recognize the device though. I tried several versions. I need to make sure my current SIMMS are not the problem before I get into verifying my design and traces.
Does anyone have a known working SIMM on a Magnum ST I could buy or borrow?
