completely untested and incomplete implementation of the SD card interface of the MULTICOMP
use SD interface in MulticompMachine and lift the speed limit on the ACIA device to better match the experience on the real machine
NPE fix and reset position on every command
more accurate emulation of the SD controller
rework SD controller emulation to work with Input- and OutputStreams (no longer load the image into a byte array)
Merge remote-tracking branch 'upstream/master'
Merge remote-tracking branch 'upstream/master'
email address update
some cleanup in the SD card controller
finer grained synchronization in TraceLog. Profiling indicates that this speeds up adding log entries quite considerably.
get writing to a certain position in a file somewhat more correct
proper status value when SD controller is in write mode
Merge remote-tracking branch 'upstream/master'
