A curious but interesting piano appeared on eBay.  It appears to
be children's size [61 keys], but is an actual electric player.
The seller lists it as an expression piano, but declares it not to be
Duo-Art, Ampico nor Welte.  I believe Ben & Mary Lilien had a similar
piano (or this might be their instrument).  It would be fun to explore
the system to try to identify the extra ports on the tracker bar.
