Hi Dan
 I have a SYM-1. You need to get a 44 pin connector ( I think it
is .153 spacing ). These were quite common until everyone started
uning 0.100 spacing. You can't have my connector though.
 I can get the pinouts for you but I don't have them here ( I'm
at work ). I can get them to you tomorrow.
 What other requirements do they have for running the games.
If it only needs the keypad and display, you can just connect
+5V and ground. If it requires a terminal, you'll need +/- 12V
as well. If you only need the +5V, you can clip onto the
protection diode that is between the two connector. The + side
it the side with the band ( Cathode ) and the ground is the
other side ( Anode ). This diode is normally reverse biased.
 Also, check to see if you need to have the BASIC ROM's. These
boards normally only came with the monitor ROM and minimum
RAM. One usually added the parts for the serial as well ( some
transistors and resistors ).
