I've just applied Frans' ST 1.5.5 patches. I got some patch failures and
some (offset) messages. The failures I knew about cos I'd done a little
'tuning' i.e. speeded up a few routines in stvdu.c, by replacing then with
assembly language, faster screen scrolling etc. However, the offsets
in stmain.c & stmpx.s puzzled me.
  So, I got my original MINIX 1.1 sources out, re-applied the 1.5.0 patches,
worked fine. Then reapplied the 1.5.5 patches... The patch failures, of
course, were gone, but still stmain.c & stmpx.s patched with lines that
were offset!!! I checked against Frans' crc's and lo and be-hold stmain.c
and stmpx.s failed, as did 6 files in lib/atari (no not stcatch.s).
   Has anyone else had these problems??? Or Frans' could you explain them?

On a different note, I'm very pleased with the speed improvment from 1.1
to 1.5.5, except WHY IS THE KEYBOARD SOOOOOO SLUGISH?????
1.5.5 seems okay on the PC so I presume it must be the ST's keyboard
device driver that's causing some sort of bottle-neck, anyone comment?

Also, de crashes rather strangely after about 1 minutes use. It produces that
old ST minix favourite 'segmentation violation', but rather strangely the
PC value is in the kernel??

signal=11 pid=0 pc=79E

It always seems to happen after the minute and I've never seen it happen
with any other command, kernel problem???
