You used to be able to find a set with connector blocks
for $200 to $300
range on EBay. But I haven't seen any pop up for a couple of years now.
There are actually two individual board on eBay now, but the they are a
bit expensive, ~$250 each. The freight change is about $200 to Sweden for
each board (don't now if they combine chipping). I'll guess I have to pay
for customs as well...
Keep an eye on machines. These options were found in
the variants of E's
(F and M) and some A's. You might have to buy another machine in order to
get this option.
If I only could find one...
Remember that you are looking for what I would classify
as a fairly rare
option on machines that are becoming rare now. There are not a lot of
these machines in service anymore.
Good Luck!
Thanks, I know that those things starts to get really rare. I could live
with a broken set.
