Please remind me prior to the QL meeting so I bring the equipment and
FPGA data.

As I wrote at several occasions, it turned out to make a difference on
which operating system I had synthesized FPGA version 1.05. If
synthesized under Windows 10, there was a stability problem that Martyn
could reproduce. If synthesized under Windows XP, everything should be
allright. Unfortunately, I never suspected such a problem with the FPGA
toolchain, and it is now not traceable. Very unlucky.

In any case, the fast SD card speed option of SMSQ/E is not an
officially permitted way to access the cards. It should never ever be
SMSQ/E default! It is a purely experimental feature used at own risk. I
have warned about it all along.

Also I'm not aware of an "auto-slow" feature. If SMSQ/E is configured to
"fast", and for some reason there is a timing problem, card access will
fail.

A save feature to use is 16 bit access to SD cards introduced in FPGA
version 1.02 and higher. SMSQ/E automatically detects this.

If the latest Minerva and/or returning to FPGA version 1.02 does not
help, I would suspect an actual hardware problem and your Q68 should be
replaced.

All the best
