I've had this problem for as long as I've had the CT60 - If I let it complete the ST RAM check/start the TT RAM check it won't boot. It usually crashes with an access fault. I've lived with it simply by using a zero second boot delay, thus avoiding the RAM check all together. But I've had some free time over the break and I thought I would revisit it.
Anyway, I got it to boot into GEM after completing a RAM check and found that while it's in this state, it thinks it's an ST!
When I got it to boot it behaved exactly like an ST. It came up in ST Medium, I could select ST LOW but could not select ST HIGH (presumably because there was no SM124 connected). No falcon modes worked.
I've flashed on the later ABE_V7F and SDF_V7D firmwares but it didn't make much difference.
I'm using the boot firmware pm 1.03c
Has anyone experienced anything like this before? Screenshots below. Thanks!

Even when I try to boot MiNT it goes looking for the 68K kernel (which I don't have)
