[Oberon] FPGA - Save / Restore OBERON.FS

[Tomas Kral]

Hi Christopher,

EDIT, need $((256*1024+1)), as it is 262144+1 where OBERON.FS starts and
1st block is not used, modulo 29.

I have in the end resorted to: 
$ dd if=/dev/sdc of=OBERON1.FS bs=1K skip=$((256*1024+1))
count=65K

`System.Watch' reports 921 sectors used, so I tempted to try
$ dd if=/dev/sdc of=OBERON1.FS bs=1K skip=$((256*1024+1))
count=921, instead.

Which goes very fast on RPI here.
