hi

I have bought 3 PachiSlo (I think one is in fact an Okislo the coins are 3cm diameter) in a flea market. none have the door key. 2 start with Error E1 and 1 wasn't starting at all.
i was able to open the non working one (unlocked by the hole below the machine), and put in place the fuse and it actually started and seems to work. All the tokens are in the Hopper, how can i empty it in order to test the machine before i can buy new tokens ? the two others i wasn't yet able to open.

the one i opened i can see: Pioneer . Okinawa island , Siolar and looks old
the 2 non opened are : bio hazard (don't find how to unlock) and dawn of dream (i think i found the latch but the door seems blocked)

thanks in advance for your help,
